STUDIO BOX (headphone distributor/amp)
The mic module 2612 manages 3 microphone channels and 3 unbalanced line inputs (AUX). It have the
same features that the 2610 but include a stage of
microphone processor with dynamic compression
and noise gate.
Line modules (2601): Manage 2 balanced stereo inputs (LIN) and two unbalanced inputs (AUX). Main
and auxiliary gains can be adjusted using 4 trims located at the front panel, to match the levels of the different sources.
Digital inputs 2602: Modules 2602 offers direct
connection to the computer via USB. It works as
external sound card, giving to the computer 2 playing
devices and 2 recording devices (PGM and AUD can
be recorder directly).
2602 modules also allow operation with Skype or
telephone hybrids because each internally generates
its own Mix-Minus, so the "Solidyne 2600" console
has two channels "Mix-Minus" for every 2602
Brief description
Input modules
All outputs are located on the Master 2607. Line
(2601 and 2602) and microphone modules (2610 and
2612) have 3 stereo sends: PGM (program), AUD
(audition) and SEND.
All input modules of consoles Solidyne 2600 manage
the audio signal electronically, that is to say, there is
not audio signal on the switches. The faders are ultra-light touch and operate managing the audio indirectly through digital control amplifiers. All input modules are programmable from the front avoiding the
use of internal jumpers.
The Solidyne 2600 consoles have a great flexibility
since they are fully modular. This feature allows to reconfigure the console without leaving the air. Most
the input modules are double. Each module has two
faders of 100mm that manage two stereo signals,
and each channel has two inputs (Line or Microphone and Aux) commutable from a button in the
front panel. There are different modules to manage
different signals, that are:
Microphone modules (2610 and 2612): The modules 2610 manage two microphone channels (MIC)
and two unbalanced stereo line inputs (AUX). The
2610 features:
• Pan-pot
• Gain control with 30dB of range (+/- 15dB) that
allows to adjust the input levels for comfortable
operation of the main fader.
• 2 bands low/high EQ, Baxandall type, with +/15dB of rage.
The PROGRAM output is the main output, used
to send the audio signal to the transmitter.
AUDITION is used to record or to hear audio in
control monitors but not on the air.
SEND is a stereo bus. It’s used, by example, to
make a mix of all input channels, except the microphones. This mix can be sent to the studio
monitors. This way the speakers will be able to
listen a return in the loudspeakers, without headphones, still on the air.
The CUE bus allows hearing the signals with the
channel off and fader closed. The monaural audio hears through an internal speaker, located at
the right of the meters bridge. CUE can be assigned to the main monitors of Control Room.
Start devices output
This output modules present in the console (stereo
mini-jack located next RJ45) can command the Audicom computer, digital audio processors or any other
device with a remote control. Activation is performed
by opening the fader and press the AIR button on
each channel.
Broadcast mixing consoles - 2600 series
Page 5
There are several modes for the cueing:
"Solo": In this mode, when a CUE button is pressed
and then another; the second CUE turn off the first
one. If all channels are set in mode "soloist"; then
only one CUE can be on. By pressing a CUE buton
that is on, it will off.
"Mix": CUE works with independence of other channels. The CUE button turns on or off each time that is
pressed. All channels defined as "Mix mode" can
have the CUE button turned on at the same time.
"Auto-off": With independence of the modes explained above, the option Auto-off turn off the CUE
when the channel is send on-air (AIR button turned
ON and fader raised). The CUE can be turned on
once the channel is on-air, but it will turned off again
if the fader is moved.
The CUE behavior is defined in the configuration of
each module; as explains at “2.4.2. - Customizable
The level of the CUE speaker is set using a knob located at the Master Module.
At the section "Control Room", there is a button
called "CUE to Speaker" that allows to send the CUE
signal to the Control Room's main monitors and
ETM-CPU faders
The 2600 uses a new generation of slide
potentiometers: conductive ceramic with “feather
touch”. In normal use, offers more than 20 years of
duty. They have a very solid construction, as the
skate slides on two sylver-steel cylindrical axis with
teflon bushings. The fader generates a DC voltage
that controls the module's internal computer. In a
2600 mixer the audio signal never passes through a
carbon track neither mechanical switches. For more
information please visit our web site.
Main advantages of this technology are:
Eliminates noise generated by dirty faders.
Maintenance free and greater useful life.
Maintains a perfect stereo tracking (error>0,1 dB).
Allows the use of conductive ceramic sliding potentiometers which offers 2 millions of operations
On-Air mics button
Located above the main fader, this button turn on/off
the channel. The button lights when is on.
Page 6
The button ON AIR switch the signal electronically;
there in no mechanical contacts. It gives an operation
clicks & plops free, due to 2600's uses a fast slope
fading action instead of the hard switch that are characteristic on the mechanical switches.
When an AIR button is pressed, turns on the tally
light (the console gives 12 V DC as tally signal).
Also, a relay mutes the studio monitors.
A Master Microphone button is located on the 2607
Master module. The purpose of this button is switch
on/off all microphones channels at the same time.
Each channel can be linked to Master Mic button with
independence. By default, all mic channels are linked
to the Master Mic button.
Expansions & accessories
The 2600 series can be customized according to the
requirements of the radio station. The user decides
how many microphone and line modules will have.
All models feature as an option the kit of wiring and
adapters for connecting the console without the need
to assemble cables.
You can also choose to include other optional features, which are described below:

(MIC 2601, 2612;
LIN 2610, 2602)
VU and stereo phase vector
The Stereo Phase Vector allows measuring the
stereo phase relationship and therefore the grade of
stereo sensation achieved. The range is 0 degrees
(mono) to 90º (maximum stereo); with inverted phase
indication (180 grades), to prevent to the operator
that a connection’s error exists in the microphones,
or among equipment’s with analogical connections
Broadcast mixing consoles - 2600 series
The analogical section is gauged in steps of 20 degrees, with quadrant of vectors. This allows following
the quick program variations. By other hand, the digital section retains for an instant the maximum value
reached by the phase rotation.
A musical program with good stereo sensation will
have averages (analogic) of 40 to 60 degrees, with
peaks (digital) of 80 degrees. Readings of 0 and 20
almost indicate a monaural signal. The indication -0
or INVERTED implies the serious problem of inverted
phase. This must be quickly corrected because the
inverted signals ‘disappear’ when they are listen in
mono FM receivers.
Studio Box is an optional accessory which concentrates in a unique box all monitoring facilities into the
Studio. Studio Box offers the following features:
5 headphones outputs with independent control level.
Output for Studio Monitors with level control.
Timer / Clock
Talkback, to talk with the Control Room operator.
Timer / Clock
a) Provides the current time while the microphone
channels are turned-off.
b) Shows a count up (minutes: seconds) when the
microphones are on the air.
The timer mode is activated when the mics are activated using the Master On-Air button. When you turn
off the microphones, the time will be retained on
screen by 3 sec and then the display will return to
‘clock mode’. If you turn on the microphones again (in
this 3 sec window) the timer will resume.
2630-VQR module
This optional module allows partially restore the voice
quality that has been degraded by telephone transmission. Can be used with the internal telephone hybrid , or with external hybrids connected to the console via "External Hybrid" connector.
The 2630-VQR module has three 100 mm faders that
allow to the operator adjust the degree of reconstruction applied to the audio; and a LED indicator showing restoration levels. The module also features an
noise gate of variable threshold.
Refer to "3.6 Module 2630 VQR" for the operation of
this module.
AoIP output
The output "AoIP" streams the program mix to another console Solidyne 2600. This streaming also be
decoded with any streaming player software; or by
using a Solidyne ADA102 decoder.
AES-3 outputs (AES/EBU)
Optionally, models XL & XX can have AES-3 outputs
for program and audition.

Setup and connections
NOTE: in all cables the channel marked with a red label
is the right channel.
About the wiring
The consoles come with their inputs and outputs with
RJ45 connectors and are wired using multipair cable
shielded CAT-5. With the advent of audio over IP
(AoIP) various manufacturers started using RJ45
connectors and shielded multipair cable to replace
the various audio connectors, to standardize the entire installation with a single type of connector and a
unique type of cable.
Additionally, the use of structured cable for connection between remote devices facilitates the installation anywhere in the world, due to availability of components and assembly tools used in data networks.
The multipair cable end that connects to the audio
device (microphones, speakers, playback devices)
still require standard audio connectors. For this, the
RJ45 cable provides termination sections with RJ-45
female at one end and connector audio as needed at
the other.
MIC & LIN analog inputs. By each MIC or LINE channel
there are:
• One RJ45-Male to RJ45-Male; length 2,5 m + one
Adapter RJ45-Female to 2 x XLR-Female (Left & Right)
In MIC cables ONLY the Left is used.
• In line modules (2601) will be provided a half of cables
with XLR-F and the other half with RCA connector.
USB inputs: For each module 2602 are included:
• 2 USB cables; length 1,80 meters
NOTE: If using Solidyne's DH400 Telephonic Hybrids,
or another hybrid with independent mix-minus, ask
cables SOL45.
Outputs of Master 2607
2 cables RJ45-M to RJ45-M, length 2,5 meters + Adapter
RJ45-F to 2 x XLR-M (channels Left and Right) (One cable to balanced PGM output and another cable for balanced AUD).
1 cable RJ45-M to RJ45-M length 2,5 meters + Adapter
RJ45-F to miniplug stereo (SND unbal output).
1 cable RJ45-M to RJ45-M, length 2,5 meters + Adapter
RJ45-F to 2 RCA (input for external tuner).
Note 1: if the console have the optionals /VI, /AoIP each
optional includes its cable (2,5m.
Note 2: if the console have the optional /AES comes
with a cable of 2,5meters + adapter to 2xXLR (one for
AES- PGM and another for AES-AUD). Additional cables
If additional cables are needed, the options are:
Solidyne SOL45 wiring kit
Solidyne provides (as option) different kits of cables
“SOL45”, designed to make the installation of a Solidyne 2600 console in a few minutes. This wiring kits
are made using shielded multipair CAT-5.
SOL-25 /SOL-50 Cable RJ45-M to RJ45-M, flexible
shielded, length 2,5/5 meters.
Note: Longer cables can be used using CAT-5 shielded
multipair and shielded RJ45 connectors.
2. SOL-XLRM Adapter RJ45-Female to 2 XLR-Male connectors (balanced) Standard kit
The basic option is "SOL45 / 10" that connects consoles up to 10 audio channels. Consolas with more
than 10 channels will use the "SOL45/NN" kit being
"NN" the number of audio channels.
SOL-XLRF Adapter RJ45-Female to 2 XLR-Female connectors (balanced)
SOL-MINIM Adapter RJ45-Female to 1 Miniplug 1/8”

Parasitic signals
Generally, are considerate parasitic signals all unwanted signals that appear in audio lines. A common
type are denominated humming, low frequency signals (multiples of 50/60 Hertz) caused by the interaction of electromagnetic fields coming from the AC
line. When the interference source is a magnetic field
(generally originated in a supply transformer) the resultant interference will be denominated electromagnetic humming. When the interference is due to such
electric potentials as cables that take supply tensions, that are elevated in comparison with the audio
signals present in the circuit, you will be in presence
of electrostatic humming. The distinction is not
merely academic, because the resolution of a problem supposes the knowledge of the noise type to apply the correct solution.
Examples: To minimize the reception of electromagnetic
humming in the wires, remember the following rule: "THE
It implies that the cables will be tied very close, like the
shielded twisted pair audio cables. They should pass far
away from any transformer or devices that manage high-intensity currents. Is important to remember that a wire can
be good shielded, but if his conductors don’t complete the
conditions of minimum area it will be susceptible to take
magnetic humming.
Other parasitic signals are: AC HUM, RADIO FREQUENCY and CROSSTALK. As hum noises like the
radio frequency are originated by electromagnetic
fields of high frequency; the first ones are originated
by disturbances due to the connection and disconnection of equipment’s to the AC line, the seconds
ones are generated by communications transmitters
or industrial equipment. If these signals penetrate
into audio lines, with sufficient intensity, can surpass
the action of the special protection filters, and to
reach some sensible part of the input stages. In that
case, the interfering signals can be demodulated and
already turned audio signal, and will be amplified by
the rest of the system. It is fundamental, therefore, to
maintain the interference within reduced margins. It
is obtained avoiding very long audio lines, with aerial
sections or that pass near of transformers or RF
transmitters. For protection against very high frequencies is advisable to use double shielded cables,
guarantied by the manufacturer
Page 10
CROSSTALK is the reception of signals coming from
other lines of audio. This, like all unwanted noise, it
can be supposed controlled when its level is below
the level of the system residual noise. Then, all considerations mentioned for the case of buzz are valid.
RF interference
2600 consoles have numerous internal protections
against RF fields, for the AM and FM broadcasting
band. When the transmission station is installed correctly, there will be no interference problems, still
with FM equipment of 50 kW installed in the terrace
of the radio station. Nevertheless, when the antenna
is badly positioned with respect to the Studio or has
severe SWR problems, then it does not have the
minimum value of field intensity, downward. Or
maybe there is a faulty ground connection, then,
strong standing waves will appear on the cables of
the Studio that can induce high electrical currents inside the audio console.
Symptoms: If the interference takes place at the
A.M. band, the sound transmitted by the A.M. radio
will be listened in the loudspeakers on background
(or at buses PGM, AUD or SEND). In case of FM
transmissions, the interference inside the console demodulates the A.M component of the FM carrier;
(usually hum from power supply) causing background humming, because in many transmitters of
FM, the final output stage is not powered with stabilized tension. Therefore, if console 2600 presents
humming, please make a test shutting down the
transmitter a few seconds to check if the problem disappears. Sometimes, an FM transmitter with the output stage badly calibrated also produce interference
in which you can hear the transmitted audio (due to
the misalignment a part of the FM modulation is
translated to AM modulation).
Solution: 2600 consoles already have internal filters
to avoid the RF interference. Therefore, if interference’s appears, normally is caused by installation
problems on the transmission station that generate
elevated currents in the wiring of audio on the Studies, due to the standing waves. These currents circulates inside the cabinet of the 2600, and enters to the
console when overpass the barriers that impose to
this currents the built-in RF filters. The solution, then,
must be external to the console.
The solution is to acquire ferrite O-rings of 60 mm
diameter, to allow passing the cables and connectors. They will be used in each one of the D25 connectors, in the inputs and outputs. The total set of cables that goes to each connector, will have to be
twisted with a complete return around the ring (see
2.3.3 - Wiring).
Broadcast mixing consoles - 2600 series
Inputs & Outputs connections
Rear Panel
Fig.3a Rear panel– power source
Fig.3b Rear panel– connectors
At left, the console's rear panel have the on/off switch,
the main fuse (1 Amp) and the AC connector (Interlock
power-cord, factory provided). The console can be
used with 110/240 VAC 50/60 Hz, with automatic selection (switching power source).
The rear panel also contains the connectors for the
loudspeakers monitors, headphones, and telephone
lines with the associate phone sets and the output to
plug the ONAIR light (Tally).
All inputs connectors are located under the rear panel,
using RJ-45 connectors. Remember: good connections between the console and audio equipment are
very important question to guaranty a sure and free of
flaws operation. For that, we recommend you take the
necessary time to carry out the wiring of the console,
with a great care and always using high quality components. A good solution is to acquire the wiring kit
Solidyne SOL45.
The outputs "STUDIO" and "CONTROL ROOM" are of
line level, designed to be used with powered speakers. The connectors are TRS 1/4”. The output level
adjusts from Master module with the knobs “Sudio”
and “Control room” respectively.
STUDIO and CONTROL ROOM have independent
outputs, using ¼” jacks connectors. The STUDIO output allows to connect up to 8 headphones. CONTROL
ROOM output supports up to 2 headphones. The
headphone outputs have protection against accidental
short circuits.
At the console, the operator has independent level
controls for Studio and Control headphones. We recommend to install at the Studios the Solidyne Studio
Box (optional): a headphones amplifier/mixer. This unit
is placed on the table and manage up to 5 headphones with independent volume controls. In addition
StudioBox offers talk-back to the control room.
The STUDIO LIGHT output gives 12 volts / 0,3 A when
one or more microphones are on-air. This allows to
connect up to 5 LED’s lights (12V/60mA).
As alternative, the outputs “Starts Devices” can be
used to manage individuals lights for each microphone.
The electric circuit is shown in the general connections
diagram (please see the
Broadcast mixing consoles - 2600 series
Page 11
FUSE: The on-air light is protected by an internal fuse of 1A. If the
fuse blows, you must to remove the rear panel to replace it. This
fuse is located near to the tubular tally connector.
The Hybrid 2607 manages 2 telephone lines and 1 cell
phone input. Once connected, the rejection factor must
be re-adjusted to be adapted to the local telephone line
impedance (please see 3.2.1 – Hybrid 2607)
At the rear panel there are five RJ-11 connectors. Two
are for telephone lines inputs; two are for connecting
the associated telephone sets (Production Phones) and
the fifth is for the cell phone. The lines can be connected directly to the radio station's PBX or directly to
the public telephone system.
The hybrid inputs have internal filters for RF rejection,
effective in AM, FM and UHF bands. The telephone
lines have internal high tension protection using Metal
Oxide Varistors. But we recommend having additionally a good external protection.
In case of damage on the internal fuses, these can be ordered.
See Chapter 4
Phone lines protection
The telephone lines must have protection against lightning and electrical surges. Please, see general protection diagram at the end of this chapter.
Connecting a cell phone
The cell phone connects directly to “CELL” RJ-11. An
adaptation cable is required for connect the cell phone
to the console. This adaptor defers according to mark
and model of the cellular. The cellular connects to the
hybrid using the “hands free” connection. Consult with a
Solidyne dealer by this accessory. For make this yourself, please read the following indications.
Will need a special cable RJ-11 whose connection will
depend on the brand and model of the cell phone. Purchase the “hands free” accessory that correspond to
the cellular and consult the documentation to make the
connection (see next image).
Basically, which transmits the cell phone through the
“hands free” mode is the audio signal of the cell telephone: microphone and loudspeaker. The Hybrid receives, via cell phone, the remote audio (that is to say,
the audio of who is talking at the other end of the line).
On the other hand, the hybrid sends to the cell phone
the audio that originates at the studios (return signal).
Usually, microphone and loudspeaker of the cell phone
are disconnected while “hands free” mode is used.
Page 12
Connecting an external Hybrid
The female TRS ¼” labeled “EXT HYBRID” gives PGM
send (tip) and return from Hybrid (ring), to connect an
external Hybrid. The PGM send is Mix-minus: it includes all the signals of the PGM Bus, with exception of
the Return from Hybrid, to avoid a feedback loop.
The signal that is incoming by the external hybrid’s return, is routed to the same circuit of control that the signals of the internal hybrid. Therefore, the "Hybrid Fader"
will behave in the same way that it works with the telephone lines connected to the console; sending the signal to the air or to CUE according to the fader position.
When connects an external hybrid, the internal hybrid
remains active and can be used with independence of
the external hybrid.
The lines connected to console and the external hybrid
can be in conference.
Remember: once a call is on-air, the cue channel stays
disconnected, so the user must use a phone associated
with that line to speak privately with the second caller.
When make a conference between internal and external hybrid, take care with the output level of the external hybrid, so an excessive level can cause feedbacks.
The RJ45 on the right (Master Module back side)
provides connection to the accessory Solidyne Studio Box. Studio Box is the solution for sending all
monitoring signals to the study. Includes distribution
amplifier to connect up to five headphones, connection for speakers, and Talk-back system for commu-

The line inputs are stereo, electronically balanced
(transformerless). It allows the connection of high-level
signals, balanced or unbalanced. Input gain adjusts
from the frontal panel with the GAIN trims (L & R). In order to unbalance this inputs, connect the negative (-)
pin to GND and positive pin to signal (see “2.3 – Connectors and wiring”).
AUX inputs are unbalanced stereo. It manages
-10dBu / 10KOhms and +4/+8 dBu line levels. Input
gain adjusts from the frontal panel with the GAIN AUX
trim (L&R).
The impedance of LINE and AUX input is bigger than
10 Kohms (Bridging inputs). This is compatible with all
current equipment (sound cards, CD-player, audio interfaces, etc.). But if you need to adapt the input to 600
ohms, place inside the connector a 680 ohms resistor in
parallel with the input.
Use professional tuners with outputs of low impedance
(600 Ohms). In case of use consumer tuners, you must add
a line amplifier between the tuner outputs and the “Air” input
of Master 2607. This line amplifier is for adapt the tuner output to low impedance.
CUE input: Master 2607 have a CUE input, designed to connect an output of a computer. This way
is not necessary to use additional speakers next to
the computer.
This input requires a special cable that connects to
the Master's RJ45 “On air in/Cue In” (see “2.3.3 –
Additional signals of Master 2607”).
Connectors and wiring
General recommendations
a) Consider to buy the wiring kits SOL45 (2.1.1
“Solidyne SOL45 wiring kit”).
b) To arm the cables, use shielded RJ45 and cable
of good quality. Remember to join the connector's shield with the shield of the cable.
c) Avoid the cables are hanging from the connector.
Use cable guides to distribute cables.
d) Avoid to mix cables with audio with AC cables.
Use different ways for each case.
e) If you hear background hum, it can be produced by RF stationary waves, induced from
the FM antenna. In this case, you must install
ferrite o-rings (60mm diameter) in all input &
output cables like shows the left image (see
2.1.2 – RF interference).
Microphone inputs
Microphone inputs are electronically balanced. The
gain adjusts from the frontal panel with a trim control
with 30dB of range. The pan-pot allows change the microphone position in the stereo image. AUX inputs are
similar to line modules, but don't have gain presets. The
MIC modules use RJ45 connectors for mic and aux inputs. Please see connections at 2.3 ‘Connections and
The Master Module
PGM and AUD outputs are electronically balanced, with
a high reject to common mode signals. To unbalance a
balanced output, only connect the positive pin (+), and
leave unconnected the negative one (-). SEND output
is stereo, unbalanced.
The nominal output level is: 0VU = +4dBm. When a
balanced output is connected to unbalanced input, its
level is reduced in 6 dB, therefore 0VU= -2dBm. Notice
that if some nonprofessional equipment connects to the
2600's output, possibly the level will be too high and
some clipping will occur. In this cases use a resistor attenuator to reduce the level.
ON-AIR input: This is a stereo input to connect an external tuner. Both the studio and control room, must be
heard the tuned air transmission, because the transmitted audio is processed and therefore sound levels
change with respect to the signal on the console.

The 2602 module connects directly to the computer via
USB. Each channel is recognized by Windows© as USB
external sound card. In this way, the audio is send directly
from the computer to the console, without leave the digital
domain. In addition, the 2602 provides two analogical balanced inputs. Balanced inputs are available on RJ45

Brown Mix-minus to use with Vo-IP software
2602 modules have the ability to cancel its own signal on sending PGM USB (mix-minus). This allows to
use the console with any VoIP communication software (eg Skype). In the VoIP software is assigned as
the audio source (mic) USB device containing PGM
signal. As output device USB device module 2602
(USB-1 or USB-2 as you want to use channel A or B
module) is assigned.
In order to the channel operates in mix-minus mode
jumpers must be placed in the circuit board (next to
RJ45 connectors). The following figure shows the location of the jumpers. To mix-minus on Canal-A
place jumpers JP1 and JP2. To mix-minus on CanalB place jumpers JP3 and JP4.
The level of the digital signal is set according to the standard K-15. The 0 VU (+4 dBu) corresponds to -15 dBfs at
USB output. There are 15 dB of headroom before clipping
(above +4 dBu).
USB connection
Each USB channel is independent and can connect
to a same computer or two different computers. Both
channels are compatible with USB 1.1 and 2.0.
Connect the module “2602” to any USB port of a
computer running Windows©. When connecting it,
Windows© recognizes the “2602” and install the drivers. Additional drivers are not required. Each channel
will appear on Windows like one stereo USB audio
device and one stereo USB recording device.
When a USB channel is plugged, the display on the
module will show “PC4” indicating that one stereo
play channel and one stereo recording channel are
active. If the second USB channel is connected, the
display will change to “PC8”; indicating that the eight
channels were recognized (2 stereo outputs and 2
stereo inputs).
To check the available sound devices, go to “Windows Control Panel > Sound devices > Audio”. Here
the default sound devices are defined. Remember to
update the settings on the audio applications.
In addition, the module 2602 offers two sends by
USB that appears on Windows as “USB recording
devices”. 2602's Channel-A gives the program signal
(PGM) and the 2602's Channel-B sends the Audition
signal (AUD). The USB-PGM out can be used, for
example, for web-casting.
Before connecting the USB cable to the computer, make sure that
both the console and the computer have an effective ground by
power cords. For safety, connect a tester in the range of 25VAC between the chassis of the PC and console and verify that the voltage
is zero. Only then connect the USB. If there are differences of tension, the USB port on the console or the computer may result damaged.
We recommend do not change the USB cable to other USB ports, to
avoid that Windows change the order of USB devices.
Windows 7: Verify that the audio recording device was properly recognized. If Windows 7 recognized it as "microphone device", the
recordings will be mono (the same signal in both channels). To correct this: Control Panel → Sound → Record → choose the USB device (shown as USB microphone) and click [Properties]. Then select
the tab "Advanced", display the menu of formatting options and
choose a format for stereo recording (2 channels, 16 bits, 44100Hz).

Customizing the modules
Configuration mode
According to the connections and use, some console's modules can require a customized configuration. This configuration is programmed into each
module as follows:
1. Switch off all assignments and close the faders
A and B in the module.
2. Press and hold any of the buttons AIR. After 5
seconds the module enters in mode "setup"
and several buttons start flashing.
3. Each button enables (on) or disables (off) one
function (see 2.4.2).
4. To confirm the changes, up and down any
fader of this module. The module flashes and
returns to be operating (with all the buttons off).
By default, all microphone modules are switched-on
when master MIC button is on-air, but this feature can
be disabled for each channel. That’s very useful for
Dj’s and showman's who talks on-live from the control
room. In this case, the microphone located in the control room will not be on-air by the Master On-Air button.
Radio stations in which studio and control are the same room
can connect the monitors directly to “Studio speakers” output.
In DeeJay mode, that is, when the speaker operates
itself the mixer console and talks from the Control
Room; the Control Room speakers monitors are
muted when this mic is on-air, to avoid feedback; and
“auto-cue” feature (that allows cueing the microphones after pressing the Talkback button) is disabled
to that channel.

can be active at the same time. If another CUE-SOLO
buton is pressed it will turn off a previous CUE-SOLO;
but will not take effect over other channels which working
in CUE-standard mode. If all channels are set as SOLO,
only one CUE can be active in the console.

A widely used combination is: the microphone channels
in CUE-standard mode; and line-level channels CUESOLO mode.
48V Phantom power
Built-in 48V phantom powering is standard; to operate with condenser microphones. When a 2600’s MIC
module connects to the phantom voltage, the voltage
is applied to all channels of these module. Conventional dynamic microphones can be connected without
problems to a phantom powered channel, since this
kind of microphones are designed to decouple the DC.
CUE Auto-off: [Set: is enabled with the button CUE Link to 'Master Mic' (mic channels only)

There are two features that must be changed to be
able to use a microphone at the Control Room:
a) Unlink the channel from the “Master Mic” button.
b) Enable the DeeJay mode.

used (alone or standard) the auto-off feature turns the
CUE when the channel is on the air (ON AIR button on
and fader open). CUE can be turned on again while
the channel is on the air (it will shut down again if the
fader is moved).
Link the channel to the "Master Mic" button, located in
the 2607 Master Module. By default all mic channels
are linked to "Master Mic". If this feature disables, the
channel only can be switched from its own AIR button.

The circuit “priority” of the hybrid attenuates the audio coming from the telephone line when the studio
speaker talks. This way to give priority to the speaker
in a debate (when both speak simultaneously, the
speaker is listened on whom calls) and to improve
the audio quality of the local voice. In some uses, like
sport transmissions, this effect is undesired (it is not
desired to attenuate the atmosphere of the stage
when the speaker from studies reads an announcement). The priority can be disabled quitting the
jumper JPRIORITY located in Master circuit board.
External control of Master MIC button
Connector EXT MIC CONTROL allows to turn-on remotely the “Masters MIC” button. By the other hand,
sends a positive voltage when Master button is ON.
“Master MIC” can be remotely switched joining terminals 3 and 4 of this connector (for example using a
relay). When the Masters MIC button is on, there are
15 VCC in pin 1 of the connector.

2.5 Adding modules to console
2.5.1 USB 2602
The USB 2602 digital module requires connection to
the 2607 Master module, to enable the recording on
the PC of Audition and Program signals. When you
buy this module separately, you receive a ribbon cable with 10-way connector pins.
If you do not connect the ribbon cable to the Master, the 2602
module works well, but only as playing device. When connects the USB cable, the module is detected by Windows and
the USB devices will be available, but if you try to record audio, the computer will record silence.
Broadcast mixing consoles - 2600 series
At the module
The fig.14 (see 2.4.2 – Jumpers on the modules...)
shows the 2602 module circuit board side. The connector labeled 'JD' must beconnected to the Master
with the ribbon cable supplied with the module.
When you screw the module, be sure to attach the
lock washers (star washers) in the top screws of the
module, as these washers ensure electrical continuity between the plate of the module and the console
cabinet. You can use the washers removed from the
blind panel or replace new washers.
At the 2607 Master
You must remove the Master module to connect the
ribon cable; but you don't need to unplug the Master. Locate the 10-pin connector 'JD' and plug in the
ribbon cable.
When replacing the Master module into her position,
be sure to attach the lock washers (star washers) in
the top screws of the module. These washers ensure electrical continuity between the plate of the
module and the console cabinet.
Once available the space for the 2630 module you
need to retire the Master, to connect the cable that
will join it to the 2630 VQR. This cable provides with
the module. The previous figure shows the location
of connector VQR in the rear side of the Master.
This is a 6-pins polarized connector, so that the cable can be plugged only in one way.
The module 2630 VQR has identical connector, to
which the other end of the VQR cable is connected.
This is the only connections that the module requires. The 2630 VQR DON NOT connects to the
main bus like others modules.
Place the fixation screws and power on the console.
By pressing the on/off button on the 2630 VQR
module, this stage is enabled and the NOISE CONTROL indicator lights (it trigger due to the absence
of signal from the phone line).
Solidyne “Studio Box”
MIC (to control room)
2630 VQR module
This optional module adds to the console a processing stage for improve the audio quality of telephonic
communications. If you acquire this optional module
after purchase the console, proceed as follow to
mount it into the console.
The 2630 VQR requires one simple-module space
available in the mainframe (it has the same wide of
a 2610 module)
Since it requires connection to the 2607 Master
module, must be placed beside the Master.
If your console does not have free space next to the
Master, considers moving all the modules that are
necessary to leave a place beside the Master. Is
easy to do it since the modules are interconnected
by a ribon cable with polarized connectors. In order
to retire a module of the cabinet, remove the subjection screws.
Modules and blind panels have a washer type star in the
superior screws that assures electric contact between the
module and the body of the console; in order to guarantee a
correct grounding. Does not omit to return to place these
washers after move a module.
StudioBox is an optional accessory which groups in a
single box to all signals that are needed into the Studio. It offers the following features:
5 headphone's outputs with independent level control.
Output for Studio Monitors with level control.
Tally light
Talk-back, to talk with the Control Room operator.
Usually the Studio Box is placed on the table into the
Studio; but depending on Studio architecture, a good
choice is fix the Studio Box to the wall when the table
is next to the Control-Studio window.
Broadcast mixing consoles - 2600 series
Page 21
The StudioBox connects to the Solidyne 2600 mixer
console using a shielded twisted pair CAT-5, with an
RJ45 T568B connector (5 meters length cable is included with the console). Through this cable, the
console sends to the Studio the signals for headphones and loudspeakers
At the Studios, the headphone outputs uses ¼”
stereo jack plug (TRS). Any combination of impedance can be used (16; 32 and 64 ohms).
Loudspeakers output are for the Studio monitors,
and use a 1/8” stereo TRS (minijack). This is a line
level output, so powered speakers are needed.
About Timer/Clock
The display shows the current time (when the mics
are off-air) or the time lapsed on air (when microphones are on). This function operates like the accessory “TIMER” for 2600/TM consoles. Please see
1.4.3 – Timer / Clock for more details.
In the StudioBox, the “counter mode” can be disabled
by removing an internal jumper. For make this, open
the back cover of the Studio Box and remove the
jumper (there is only one jumper). This will disable
the lapsed time on-air mode, being always the current time on display.
Using the Studio Box
About Studio Headphones
Although each headphone has its control of level; the
maximum level reached is determined at the console.
As you can suppose, what's listening also depends
on the selection done in console.
About Studio Monitors
Like happens with the headphones, the loudspeakers
output has its own level control; but the maximum
level and what you hear depend on the set done on
the console.
About Studio Talkback
The white button has two functions:
When the microphones are off-air, press the
button to speak to the Control Room. The StudioBox has a built-in microphone for this purpose.
At Control Room, the operator will hear directly
by the CUE speaker. The volume is controlled
with the trim “mic gain” located at the StudioBox. The knob “CUE level” of the la consola
2600 don't take action over the StudioBox talkbak signal. To answer, the operator at the
Control Room will use the standard talk-back
circuit of the console.
When the microphones are on-the-air, the
white button illuminates to indicate that microphones are “on-air”. Obviously, in this condition the talk-back feature is disabled.
Page 22
The trim located below the MIC allows to adjust the microphone gain, so it adjust the listening level on the Control
Set the inputs gain
These adjustments are necessary to calibrate the
input module gain, so that equal positions of faders
represent equal outputs levels in all modules. In order to set the input gain for each channel, use a sinusoidal tone of [email protected] or a calibration CD.
To adjust the input gain, play the test tone and calibrate the presets with the screwdriver provided with
the console. Left and Right presets at the front
panel, must be calibrated to obtain a measurement
of 0VU, with the faders at the center of the gray
zone (-15 dB).
To calibrate the PC channel, proceed in the same
way playing loud music or voice from the PC. Proceed the same way to calibrate other sources.
The audio equipment handle different signal levels:
The professional audio level, with balanced outputs operates at +4dBu or + 8 dBu, whereas home equipment
with unbalanced outputs manages -10dBu levels.
0 VU refers to the nominal output level. When the VU meter reaches 0 VU, the output level is +4dBu.
Use the balanced inputs of the console for professional
devices, and the AUX unbalanced inputs for home
quality devices.
USB channels don't have input gain trims. The input level
manages from the computer.
2.7 Models 2600 /IP
These models include RJ-45 output that sends
streaming. It allows:

2.7.1 STL link
In studies, the 2600 /IP console works as encoder to
establish a bidirectional link (full-duplex) between
Studios and Transmitter Plant. In the transmitter
plant, the streaming receives using a hardware like
Solidyne ADA102 or 562dsp audio processor. Set the IP
2. In the URL field defines the DNS name or IP
address, and the destination port to which
the console sends the streaming.
The setings options are accessed using any web
browser. By default the unit uses "Dynamic IP", so
that when connected to a LAN, gets an IP address
via DHCP (the router assigns an IP). The procedure
is as follows:
Step 1
Connect the mixer to the network via a standard
cable. The network must have a router, so that the
mixer obtains an IP address via DHCP. The mixer
can also connect directly to a modem-router, as it
usually also assign an IP via DHCP.
Once the console gets the IP, is ready to start working.
The green LED on the rear panel (RJ45) is blinking.
Can not find a DHCP server then the 2600/IP scans the network
for a free IP address (this can take a few minutes).
Step 2
To know the IP assigned to the console, the user
must run the application “Discovery_AoIP”, which is
available at the following link:
3. Press "Apply" to confirm the settings.
The configurations listed below require knowledge in network
The destination IP address is the external address of the
network in the Transmitter Plant, where it is connected
DECODER (static IP assigned by your ISP). When the
data packets reach the router / firewall on the other end,
should be re-directed to the DECODER IP (eg
As the 2600/IP transmitted to a specific IP address and
port, in transmission plant all packets arriving at that port
on the router address should be forwarded to the
DECODER, or a particular computer, which will turn into
audio. Identify which packets should be sent using port
forwarding. Audio settings

The file IP.exe is a self-extracting ZIP. When the user runs this file, a
folder “Solidyne IP Discovery” will copy to the HD. This folder contains the apps and instructions needed to obtain the 2600's IP address. Look for leame-readme.txt and follow the indications according the case.
Step 3
Open a web browser (eg Firefox, Internet Explorer)
and enter the IP address announced. The Control
Panel of 2600 will appears.

Using a microwave digital link
A 2600/IP console connected at the studio to a
broadband Internet can cover any distance from the
studios and the transmitter plant.
For short distances an option is point to point RF link
transmiting uncompressed audio (PCM 16 bit/48 KHz). It
uses a microwave link for 5.8 GHz (or 2.4 GHz in some
countries) using the standard 802.11.x. This band is
available in all countries and does not require special
authorization. It can cover up to 27 miles if there are no
obstacles between the extremes. Logically encoded
audio can be transported and for special applications
supports bidirectional connection.

Using the mixer
You can discriminate different areas in the console:
the input channels; the monitoring levels control,
phone hybrid and talk-back (master 2607); and the
VU-meters panel.
The audio signals coming from the PC, Satellite,
DAT, Mini-disc, Microphones, etc, enters to the console through the input channels that amplify them.
You can control all sources levels using the main
faders, and to listen the signals before send to the
air pressing the CUE buttons.
To send a channel on the air, press the AIR button
and open the main fader until reach the desired
level. The buses assignments button’s (PGM, AUD,
and SND) sends the channel’s signals to the Master
Each input section can receive signal of two different sources: Microphones or stereo Line. The
source is selected by a switch located at top of the
module. Remember that the modules are doubles:
each module has two faders that manage two inputs. Depending of the model this inputs can be:
2610 Microphone module manages 2 microphones (MIC) and 2 stereo unbalanced inputs
2612 Microphone module manages 3 microphones with EQ and processing, and 3 stereo
auxiliary inputs.
2601 Line modules manages 2 balanced
stereo line inputs (LIN) and 2 unbalanced
stereo (AUX.)
2602 modules manage two USB digital inputs
and two analog auxiliary inputs
The 2607 master module manages the monitoring
circuits, Talk-back, and telephone lines.
The turret contains the level meters that show the
program level; and a speaker for CUE.
Meter bridge
Audio meters
The last scale LED (red) has a dual function: if occasionally ligths, indicates +5 VU in the scale of average level. But if the level drops and the last LED
is retained (5 seconds), it indicates CLIPPING. The
fact that the level meter reaches the full scale does
not always mean that digital clipping occurs; only is
clipping if the last LED is retained. Take in mind that
when Vumeter is at full scale, dBfs peak reading is
lost because the peaks are "covered" by the average level indication.
The headroom is 15 dB (0 VU = -15 dBfs as AES
recommendation K15).
The 2600XL models also features level indicator for
AUDITION bus while 2600XD models incorporate
meters for the SEND bus.

To adjust the time there are three buttons: MODE,
UP and DOWN.
Pressing MODE button the adjustment

Telephone line Mini-Central
The Master 2607 manages 2 telephone lines and one
cell phone, operating as multi-line system. It allows
conferences between a journalist and 3 phone interviewees. The four peoples can be on the air, in conference, at the same time.
When finishing private conversation, release the
PHONE button and use HOLD position of the Hybrid
ON-AIR command to send the program signal to the
telephone line. This mode, named waiting mode, allows sending the program signal to the caller.
Cell phone connects to the console using the "free
hands" connector (see "2.1.5 Telephone Lines"). The
cell phone also supports conference with the lines.
Finally, when you open the ON AIR fader, the telephone
call is sent to the air, and the audio program returns to
the caller so that he can dialogue with the journalist.
The CUE return is disconnected automatically.
The operation is easy and safe against operation errors, due to its logic of security and automatic control
circuits. In spite of being an advanced call center system (and not a simple Hybrid), we will continue denominating it hybrid from now, due to their habitual denomination.
A telephone communication not necessarily must arrive at
0 VU to equal the loudness of the voices of the study.
Have in mind that the LF, that carries greater energy, is
not present in the telephone line, but in the voices of the
study. The lows are those that produce greater deviation
in VU METERS. Nevertheless, for the ear the loudness is
defined by the mid rage frequencies. So that if you note
that VU Meter “peaks lower” with the telephone line that
with the voices of the study, this not necessarily means
that “it is listened lower”. On the other hand, the audio
processor of the radio will be in charge to equal both signals. Conclusion: you do not leave the VU deceives to
you when mix voices of the floor with telephone calls.
The 2607 Hybrid must be connected as is indicated in
the Chapter 2 of this manual. The operation procedures are the following ones:
When a call is incoming; press the line button with the
blinking LED. The ‘ring’ will be listened on the CUE
speaker (this volume adjusts with the RING knob).
You can answer the call in two ways: a) From the
telephone set associated to that line or b) from the hybrid of the console. To answer from the console, press
the blinking button, the hybrid will take the line and a
pilot light will indicate that the phone line has been
taken by the Hybrid.
The ON AIR Hybrid fader must be closed so that the
communication will be routed through the CUE circuit.
Under these conditions, you will listen to the caller in
the CUE speaker. The level is adjusted using the CUE
knob. To dialogue, use the Talk-back microphone, by
pressing the button PHONE. This button is retained, so
you must press it again to listen the answer at the
CUE speaker, since it’s a half-duplex communication.
But you can dialog in full duplex and free hands,
staying pressed the button PHONE. In this mode, the
Control Room loudspeakers are muted to avoid loopbacks, so you must use headphones to dialog with the
caller (when the two lines are taken, the talk-back MIC
sent signal to both lines).
 If you listens high return with boosted basses of your own voice
in headphones; the rejection of the hybrid badly is fit. It can directly fit maintaining it the communication in “free hands” mode,
and varying preset NULL until finding the point in where the return of your own voice is smaller. This adjustment is equivalent
to the explained previously.
 If the communication listens saturated, with high background
sound, the level of preset CUE is too high. Diminishes this level
until obtaining an optimal listening. With the console a small
screwdriver is provided to make these adjustments.
Please do not exaggerate with the level on-air of a communication. Due to the analogical hybrids are not perfect,
a part of the audio sent to the line, that is the voices of the
study, is not cancelled and returns through hybrid, adding
itself to the direct voices of the study (this is what fits the
rejection). Working with normal levels this effect is not noticeable; but using the hybrid at high levels, the voices of
the study can be soiled (coloration).
To retake the communication in private mode, close
ON AIR fader and press the line button. The line will
be addressed to the associated telephone set. If the
telephone is hanged, the communication ends.
This button allows to assign the hybrid’s to PGM
or AUD bus. Sending the hybrid to AUD you can
record a communication without it leaves on-air (one
line channel assigned to PGM with music; MIC’s, hybrid and monitors assigned to Audition). Note that
when hybrid is assigned to AUD, it only receives signal
from channels assigned to AUD buses.
Return to phone line
Most of the existing telephone hybrids on the market
today, were designed over 30 years ago for analogue
telephone exchanges (PBX) Solidyne hybrids, however, have been recently designed for private or public
telephone exchanges today, which are fully digital. The
new technology Hybrids are recognized because they
have no control of air return level to phone line. This is
because inside the hybrid Solidyne uses an audio processor for return signal that includes AGC, peak limiter
& audio signal filtering. Therefore the return is auto-
Broadcast mixing consoles - 2600 series
Page 27
matically adjusted during the transmission and its level
is the maximum allowed by the modern digital telephone exchanges.
If you want to check the return level to phone line, you
must use an oscilloscope to be placed in parallel with
the telephone line and must verify that the signal is 2
volts peak to peak.
Please note that above this level the return can produce problems that will cause intermodulation distortion in the audio signal that goes to air. So in Solidyne
hybrids we use a processed return channel, to avoid
distortion at the on-air signal. There are hybrids manufacturers that maintain the return control level as they
did in the past. This allow operators to adjust "by
hunch" this critic level. This makes the voices of the reporters and interviewed people distorted or with coloration.
In Solidyne we keep a high grade of excellence in the
audio quality of the hybrid on-air sound. And that quality do not depend on the operator settings.
Note that the Solidyne Hybrid on- air audio quality of
the local journalists is ever perfect and without any coloration.
To achieve this level of quality we use a narrow-band
return filter. Then the return signal is limited to the
band 400 – 2.200 Hz in order not to distort the signal
to the air. This narrow band intelligibility remains high
(due to processing) but occasionally may seem to the
remote people that it "has little volume" because his
band is narrow. This should not worry because it is a
subjective sensation that does not affect the intelligibility of speech.
If you need to call from the cell phone, you can
make the call and next to plug the hands-free cable
to the cell-phone. Or you can make the calling with
the cell-phone connected to the console, hearing
by CUE speaker and pressing PHONE to dialog
(hybrid fader in CUE position).
Hybrid rejection adjustment (NULL)
The rejection factor expresses the capacity of the hybrid to avoid that the transmitted signal returns to the
system. Whichever greater it is the rejection factor
“more clean” will be the audio quality of the studio
voices. In order to fit the rejection, proceed as follow:
a) Establish a phone call through the hybrid. Listen it in
the CUE speaker, closing the ON AIR fader. b) Press
and hold the TEST button using a pencil c) adjust the
preset ADJ until minimizing the audio level (PGM) that
you hear on the CUE speaker. Increase the CUE level,
if needed, to hear well this minimum level.
Another method is to adjust the rejection factor
while a calling is answered in free hands mode,
turning the preset ADJ until obtain the minimum
level of your own voice at the headphones (see
Make a conference on the Air
The conference must be done previously, calling from
the associated telephone sets and sending them to the
air by pressing the line 1 and line 2 buttons. Let us
suppose that the speaker is dialoguing with an interviewee that called (or it was called) by the line number 1;
and we want to add to the chat to another person. We
make the call from the line number 2, with the associated telephone set. Once the communication has been
established, we press the Line 2 button to send it to
the air.
Using a cell phone
The work-flow is the same one that used for standard
phone lines. The difference is that the call is not taken
from the console, but from the cellular phone (you
don’t need to press the line buttons in the console).
When you answer the call from the mobile, the audio
enters to the console through "ON AIR" fader. We can
listen who calls in previous and engaging in a dialog
pressing PHONE (CUE); to leave the call in WAITING
(AUDIO SEND) or to send the call to the air (AIR).

Monitors and headphones
The Master 2607 monitoring section has two sections:
“Studio Monitor” y “Control Room”. Here you find the
monitoring selection (what signal do you hear) and the
volume control for monitors and headphones of Studio
and Control Room.
Monitor options at the Studio are:
PGM: to listen directly the main output of the console (the signal that is sent to the transmitter).
AUD: Allows you to hear only the channels assigned to AUD bus. This way, assigning only a
channel to the AUD bus, you can hear the audio
of that channel in the main monitors and headphones, while the console remains on the air.
Usually this bus output is connected to the recording system.
AIR: Switch to an external output, typically connected to an AM/FM receiver, in order to hear the
real transmission of the radio station. This is the
recommended method for all radios.
Broadcast mixing consoles - 2600 series
For the Control Room all previous options are available, in
addition of the following ones:
SND: Allows hearing only the channels that are
assigned to the SEND output.
CUE to SPK (cue to speaker): Allows to send the
CUE signal to main monitors. When this button is
pressed, being CUE pressend on one or more
channels, the “CUE” will be listened by the Control Room main monitors and headphones, while
the PGM signal remains attenuated in background.
Although this button remains pressed, it will not
produce no effect if does not have audio signal in
CUE. “CUE to Speaker” acts by audio detection
on the CUE bus, so that it only attenuates Program when audio is present on CUE bus.
Although the final level regulates from the loudspeakers and
headphones level knobs; the level with which CUE is sent to
monitoring is fixed, that is to say, it depends on the own input
signal. By such reason CUE can sound higher than the PGM
signal. If you are monitoring at a high level, agree that you lower
the level of the loudspeakers (or headphones) before pressing
“CUE to SPK” (or CUE if “CUE to SPK” is already pressed).
Into the Studio we recommend to install a headphone
distributor; like the Solidyne Studio Box. Studio Box
brings 5 headphones outputs with independent control
MIC channels can be customized (by jumper) to disconnect them from the Master MIC button. This way,
the channel only can be activated from its own AIR
The talkback system allows the operator to dialogue
with the speaker, located into the studio. The talkback
controls are located at the 2607 Master module. Solidyne uses a proprietary AutoSwitch system
To make a communication, press the Studio button;
the Control Room monitors will be muted to avoid signal feedbacks and the operator will be listened into the
Studio at the loudspeakers. The Program is attenuated
staying in background. This is made for not losing the
air program reference. Otherwise, if the order is too
long, they will lose the listening to a correspondent that
speaks from a stadium or reporting news.
When the talkback button is released, the AutoSwitch
system activates during 3 seconds CUE on all MIC
modules, to listen to the speaker's answer. Pressing
the TBK button again, this time lengthens. The operator hears the sum of all the microphones. Then, still
when the speaker is far from one microphone, be
taken by another.
Remember that when microphones are on-the-air; Studio monitors are muted, to avoid feedbacks.
If one of the microphones is used at the control room
instead the studio, you must use a microphone with
on/off switch. Make sure that the MIC switch will be at
off position, to avoid acoustic feedback. On modules
2612 you can modify the jumpers to avoid auto-CUE
on talkback in that channel.
In this way you get the dialogue by pressing only one
The unit has a built-in loudspeaker for previous listening. Each channel has a button named CUE, that allows to listen the signal present in that channel leaving
off-air (button “AIR” off and main fader closed). If you
press CUE in several channels, the CUE signals are
mixed. At the Masters, CUE knobs manages the level
of previous listening in loudspeakers or headphones
according to correspond.
CUE signal can be sent to the Control Room main
monitors (and headphones), as was explained previously.
The level of the talk-back microphone is calibrated in factory, and usually isn’t necessary to modify it. If you need to
change it, there is a preset located above the Talkback
If you have the Solidyne Studio BOX, you can talk at any
time with the Control Room (using the Talkback button of
Studio BOX); without having to hope that the operator is
watching trough the window.

The MASTER MIC button (located at the 2607 Master

Special features of 2602
The 2602 line modules offer two USB connections to
connect directly to two computers (see Connecting the USB 2602 module). There are not
operative differences respect the 2601 line modules,
but 2602 have an extra feature: the ability to use the
computer to make communications using VoIP
software (eg Skype).
They also allow the management of digital hybrid
conference, as each module generates its own output Mix-Minus. In particular using hybrid Solidyne
DH-400; Module 2602 can remotely command them
allowing an unlimited number of simultaneous telephone channels.
3.6.1 Operation with Skype
The USB connection can be used to make
communications running a VoIP software on the
computer (Skype or similar). The VoIP software must
confugured as follows:
In the VoIP software, assign the desired USB
channel as the output device.
In the VoIP software, assigned as input
device (microphone) the output of the 2602
channel-A or channel-B (which appears in
Windows as USB recording device). See the jumper settings at DB25.
correspondent jumpes, becomes mix-minus sends.
This allos to manage a grat number of channels
working with VoIP of telephone lines simultaniusly.
Audio that delivers VoIP software directly enters to
the console by a 2602 module channel.
Private comunication using VoIP
To talk privately proceed as follows:
To listen to the caller without be on-the-air,
press CUE in the VoIP channel. The audio
from the PC will be heard in the CUE
To talk, press and hold the CUE button. This
enables the talk-back microphone in the
2607 Master. Take in mind that this
communication is half-duplex, so you can not
listen to the other people while you speaking.
When you release the CUE button, talk-back
mic is muted and the CUE turn on.
To send the comunication on-the-air, press
AIR button and open the main fader.
Page 32
Jumpers into 2602's connector
In order to enable the private circuit, you need to plug a
DB-25 connector in the 2602 module. This connector
must joint pins 5-15-17 if VoIP is used over the Channel-A; and pins 6-19-20 if used over the Channel-B.
2630 VQR
Hybrid’s processor module
If you acquired this module after purchase the console,
please see “Chapter 2 – Installation” to connect it.
Solidyne VQR (Voice Quality Restoration) is a type
of audio processing that allows improving the audio
quality of a telephone communication. This technique
bases on the reconstruction of the spectrum lost due
the transmission.
As you know, the bandwidth transmitted through a
telephone line reduces approximately to 300 Hz –
3.000 Hz, because this is the range of the human
voice. Therefore, the components of low and high
frequency, presents in the original signal, are lost in
the transmission. These components, although are
not important for the understanding of the words,
ARE VERY IMPORTANT FOR THE AUDIO QUALITY, because they give “weightiness” and “presence”
to the voice. System VQR really reconstructs the
bass of the voice, reaching the frequencies of up to
50 Hertz, being able also reconstructing component
of high frequency to recreate the highs that are of extreme importance to obtain the presence sensation.
In addition, stage VQR has a third control to improve
to the dynamic range, obtaining values of up to 70
dBA in a telephone transmission.
This processing is applicable as much to calls by terrestrial lines, like a calls made through the mobile
telephony. Although the reconstruction reaches to
callings made using the internal microphones of the
cellular or the fixed telephones, the best results are
obtained using a portable audio console and dynamic microphones of good quality.
For details on VQR, you can consult the information
available in the section “Technical Documentation”
on our Web site.
3.7.1 Using the VQR
Module 2630 VQR works as much with the internal
hybrid of the 2600 console like with any external hybrid; connected to the Master 2607 using the “External Hybrid Send & Return” connections.
Broadcast mixing consoles - 2600 series
The module has a complete panel with luminous
level indicators that shows:
Degree of restoration for low frequencies.
Degree of restoration for high frequencies.
Action of the Noise Cancel
Manages the level of lows added to the original
signal. With the fader closed there is no reconstruction for low frequencies.
The level of reconstruction, or the amount of low
frequencies that is possible to add to the signal,
depends on the audio quality of the telephone
line (all communications don’t transmit the same
bandwidth) and the telephone or microphone
used at the other end. Obviously, same results
are not obtained using the small microphone of a
cellular telephone or a microphone of good quality
with a portable console. at least quality has the
transmission (smaller bandwidth) smaller will be
the action of VQR processing.
Make sure to listen to the processing in the main
monitors of the control room, to avoid an excessive reinforcement of lows in the processed signal; that can take place if you are monitoring the
communication using small headphones or loudspeakers of bad quality.
Hi band
It controls the level of high frequencies added to
the original audio coming from the telephone line.
With the fader closed the high processing deactivates.
The action of this control is much more critical
that the Low Band, since an excess of highs processing will generate an “artificial” sound; and in
extreme case “crashed high” sound can take
place, that will be annoying to the listener.
The VQR processing can be enabled or bypassed
pressing the on/off button on the module. By pressing this button the VQR stage activates and the
MID BAND indicator lights, (or NOISE CANCEL if
the fader NOISE is open, due the absence of audio
signal). With the button up the module is bypassed and the audio of the calling is sent on the
air without processing.
The user adjusts the amount of processed signal
using the faders “Low band” and Hi Band”.
Both controls even have an ample rank of work,
making possible the processing in telephone signals whose bandwidth is very restricted.
Low band
On the other hand, consider that an A.M. radio
can require more emphasis in high frequency than
a FM; to obtain a well-known improvement on the
air; therefore the control Hi Band has an ample
rank of action.
The reconstruction level -or amount of highs
added to the signal- depends on the quality of the
transmission. This stage will be affected, mainly, if
the line has much background noise.
 The optimal level of work is obtained when the indicator
MID BAND lights with the signal peaks. Lower audio levels can affect the behavior of the VQR processing.
NOISE Control (expander)
This control is used to reduce the background
noise present in the phone line. It acts only during
the silences in the conversation, attenuating the
level of the signal to suppress the noise. This is
Broadcast mixing consoles - 2600 series
Page 33
quick action gate reason why its effect is imperceptible with normal levels of noise, not affecting
the word.
The NOISE fader acts changing the threshold of
the expander/gate. When de background noise is
under this threshold the expander/gate works attenuating the noise.
Closing the fader the expander/gate is turned off.
When opening the fader increases the threshold, that is to say, the signal level below which
the expander/gate goes off. The action of the expander/gate is showed in the display by the
NOISE CONTROL indicator.
Remote control
Models with Ethernet controller (option /VI) can be
managed remotely via LAN, using any web browser
on any operating system.
The console connects to a LAN from the RJ45 connector labeled "IP Control", located at rear panel of
Master 2607. This connection uses a standard Ethernet cable. By default the console is set to work with
DHCP. When the console connects to a
router/switch, it will assign an IP address.
How use this control
Increase the threshold raising the NOISE fader
until eliminating the background noise. An insufficient level will do that the noise remains, although
reduced. An excessive level will cause that the
audio appears “intermittent”.
Next some important tips to take in mind when
use this control:
 If the background noise in the communication is very high, will be always over the maximum threshold (fader at top) with which the
expander/gate will not work correctly.
 Consider that the expander/gate releases
whenever the audio signal is below the
threshold. If the background noise is very
variable in level (noise from a street, for example), it agrees not to use the NOISE CONTROL to avoid that during the pauses it activates and deactivates generating an intermittent background sound. In these cases it is
preferred to leave the ambient noise.
 Also can happen that the background noise
is very notorious (a strong humming or buzz)
and although the gate can attenuate it during
the pauses, the effect “appearance” and “disappearance” of the noise is more annoying
than the own noise, due to a psycho-acoustic
phenomenon according to which the ear “is
accustomed” to the floor of constant noise
when concentrating the attention in the word.
According to these advice, the good criterion of
the operator will determine when it will make use
of the noise gate and in which cases it will prefer
not to use it.

Once the 2600 / VI is connected to the router, the
user accesses the Virtual Interface Control from any
computer on the LAN, using a web browser and typing in the address bar the following:
If the connection is successful the login screen
of the 2600 / VI appears. See "3.8.2 - Virtual Interface" on instructions from the Virtual Control
If the login screen does not appear:
a) Check the connection of the console to
the router on the LAN and try again.

In order to obtain great results with the 2600 consoles
that Solidyne guarantees with its design and manufacture, we recommended following the indicated operative procedures in this manual.
the reverse side. This unique protection technology allows for a full protection from hands abrasion. The
2600 console will remains unaltered after a full life of
The unit have a main fuse (1A) located at rear panel.
The phones lines have a circuit to protection against
discharges of high voltage. This circuit is mounted in a
separated plug-in board, to facilitate its replacement in
case of damage.
On console’s temperature
The rear panel of the VU-meters turret is made in aluminum and dissipates the heat produced by the power
supply and audio amplifiers.
In models XS and XL the value of overheating with respect to the atmosphere is of around 68º F. That is to
say, with a normal atmosphere of 77º F the back panel
normally will work at 113º F.
In models XL with 16 channels working with 110 V AC
(the extreme condition) the temperature can reach
131º F (with 77º atmosphere) in the back panel. This it
is a safe value and the console is designed to work at
these temperatures, so you don’t worry about it.
Preventive maintenance
The preventive maintenance is carried out during the
normal operation of the console to avoid flaws. The
2600 console is manufactured using hi-tech integrated
circuits and heavy-duty electronic components, that
guarantee an excellent reliability and allows eliminating the routines of preventive maintenance.
The linear faders manage only DC current. Under normal conditions, the useful life of these faders exceeds
200.000 full cycle operations. Use carefully: don’t’ kick
the faders and don’t’ push them with excessive force.
Special models are provided with the new ESF electrostatic fader technology, without moving contacts,
that lasts 25 years.
Parts Replacement
All modules are assembled using connectors. The inputs modules can be disconnected and reconnected
while the console stays on the air (Hot Swap technology). The main faders have connectors too. They are
mounted to the chassis with two screws, so its replacement is very easy.
Maintain the room clean and free of dust. The surface
of the console can be cleaning using a very smooth
detergent (like are used for painted walls) and a
sponge or fine cloth hardly humid. NEVER USE alcohol, benzene or petroleum derivatives.
Take this rule: NO SMOKING at the control room. The
cigarette ashes are LETHAL for the faders and affect,
in addition, to other equipment of the radio (CD players, minidisks, etc.). By the same reason, don't drink
or eat while you are working on the equipment.
If after using the console for a long time, you note that
the faders become difficult to handle (hard to move) or
fails, probably they are dirty. In order to clean it consults with the technical department of your radio. They
will have to use special products. If after cleaning the
faders the faults remain, consults with your Solidyne
dealer to acquire the corresponding spare parts.
Service Manual
You can obtain a service manual of this equipment,
free costs. For it the Director of the radio must send by
FAX to Solidyne a signed Agreement of Confidentiality
(the text is available in our Web). You will receive a
link to download the service manual, which include
schematics; components layouts and technical information. The document installs in a PC that will be
used in the Technical Office of the radio. Downloaded
manual only can be viewed in that PC.

Specs & Measurements
General Measurements
The radio stations that have their own Engineering Department sometimes needs to carry out measurements
when receiving the console. Also some engineers estimate convenient to carry out every five years a general
inspection of the console to verify if the specifications
continues being perfect.
The following methods and comments refers to Technical
Specifications that figure at the end of this chapter.
Before starts any measurement, make sure that all modules
present the following conditions: PAN POT at the center position.
PGM, AUD, and SEND buttons released; AIR and CUE must be
off. Be sure the console is properly grounded and no RF is
present at the measurement Laboratory.
Connect an audio generator to a microphone input.
Connect an audio level meter and an oscilloscope to the
PGM left output (then repeat with the right). Connect a
600 ohms charge to the output.
Set the audio generator to 1 kHz -80 dBm. Select MIC
and PGM on the channel which the generator is connected. Enable the channel pressing the AIR button.
Move the main fader from this channel to the maximum.
Increase the gain of the module until obtain +4dBm at
the output.
Page 40
Move GAIN to the minimum. Change the generator to
-45 dBm. Move the fader until you verify that can obtain
+4 dBm without clipping at the output.
Change to the right input of this channel (or to another
module) and repeat the procedure.
Connect the generator to left input of a line channel, with
a level of -20 dBm at 1 Khz. Verify that the oscilloscope
and audio level meter are connected to the left PGM
output. Select LIN and PGM in the channel under test.
Enable the module by pressing the Air button; move to
the maximum the GAIN preset and move the main fader
until you verify that can obtain +4 dBm at the output.
Change the gain control to the minimum; and increase
the input level up to +18 dBm; move the fader until obtain +4 dBm at the output without visible clipping.
Increase the gain with the main fader until obtaining +15
dBm at the output. Use this value like reference. Connect the balanced input in common mode joining both
signal terminals. Then, verify that the output level decrease at least 40 dB. Change the test frequency to verify the common mode rejection specification.
Repeat for the right input of this channel or for another
Broadcast mixing consoles - 2600 series
Aux Input
Connect the generator to the AUX left input. Select AUX
and repeat the procedure explained for the line channels, with levels of -25 dBm and +4 dBm. Take in mind
that the common mode rejection isn’t applicable for this
Balanced Outputs
All the measurements must be carried out in the same
way that the unbalanced outputs, but disconnecting of
GND the instrumental used and connect it between the
two balanced terminals.
Another possibility is to measure all in unbalanced mode
(only one pin), adding 6dB to the results.
Unbalanced Outputs
Connect the audio generator to line left input; adjusted
at +4dBm/1KHz. Connect an audio level meter and the
oscilloscope with a charge of 600 ohms, to the SEND
left output (pin 9 of the master connector).
In the channel under test, select LIN and SEND. The
other buttons must be out.
Enable the channel by pressing the AIR button. Open
the main fader up to -10 dB. Change the generator level
until reach the limit of clipping. Verify that the oscilloscope shows a greater or equal level +18 dBm.
Repeat for the right channel (terminal 10 of the Master
connector). In the previous condition, repeat the output
measurement for mono PGM output.
Connect the microphone input to an audio generator.
Connect the audio level meter and the oscilloscope to
the output. Charge this output with 600 ohms.
Adjust the generator to 1 kHz / -80 dBm. Select MIC and
PGM in the channel. Enable the module by pressing the
AIR button. Take the main fader and the gain control to
the maximum position. The difference between the obtained output level and -80dB is the gain of the console.
Frequency Response
Connect the generator to a microphone input. Connect
an audio level meter and an oscilloscope to the output.
Load it with 600 ohms. Change the audio generator to 1
kHz / -50 dBm. Select MIC and PGM in the channel.
Enable the module pressing the AIR button. Move the
main fader to the value -10 dB. Change the gain of the
module or the generator output until obtaining +4dBm at
the output. Change the frequency between 20 and
20.000 Hz and verify the frequency response.
Staying the conditions of the previous item, connect the
generator to both microphone inputs (right and left).
Connect a digital phase meter to the channels left and
right of the program output. Load each channel with 600
ohms. Change the generator’s frequency to measure
the phase. The variation will be smaller than 2 degree
between 50 Hz -15 KHz.
Stereo Tracking
Maintain the conditions of the previous item. Change the
generator frequency to 1 kHz. Take the main fader to
the maximum. Adjust the Pan-Pot to obtain the same
level in both channels (L & R) of PGM output. This level
will be in order of +10 dBm. Now, move the fader between 0 and -30 dB and measure the difference among
the levels of both program outputs. This difference will
be below +/- 0.2 dB
Harmonic Distortion (THD)
Connect the audio generator at 1 KHz / + 4 dBm, to a
left line input. Connect a Harmonic Distortion meter and
the oscilloscope to the left program output. Load this
output with 600 Ohms. Then, select LIN and PGM in this
channel. The other switches should be out.
Enable the module by pressing the AIR button. Take the
fader to the maximum level (0 dB). Then, change the
preset line level until obtaining +4 dBm on the left output. Measure now the total harmonic distortion. Change
the frequency between 30 and 15,000 Hz and to check
if the distortion is below the specification. Repeat for
right channel.
Reduce now the level from the generator to -50 dBm
and connect it to the microphone input. Take the fader
to 0 dB position. Select MIC; change the level from the
MIC preset gain, until obtaining + 4 dBm at the output
and to proceed like in the previous item.
It is necessary to keep in mind so that this measurement has validity,
the following conditions must be verified:
1. The measurement chain must have a distortion smaller than 0,002%.
2. The distortion components, just as they are seen at the oscilloscope
screen, connected to the output of the THD meter, must be clearly distinguished from the residual noise and buzz.
Equivalent Input Noise
Connect the audio generator to a microphone input.
Load it with 600 ohms. Connect to PGM output an audio
level meter with A-weighted filter. Change the generator
output to 1KHz / -45 dBm. Select MIC and PGM in the
channel under test. Enable the module by pressing AIR.
Set the main fader to -10 dB. Change the gain control
until obtaining +4 dBm at the console output (this is the
reference level: REF).
Broadcast mixing consoles - 2600 series
Page 41
Now, replace the audio generator by a resistor of 150
ohms placed inside the D-25 MIC input connector. Measure the residual noise in the audio level meter with “Aweighting” filter. We will denominate it Vn(dBm). Verify
in the oscilloscope that there is not any buzz; only random noise signal. In order to eliminate buzz, reconnect
the grounds of the measurement instruments so that the
buzz disappears. The level of equivalent input noise will
EIN = Vgen + Vn-REF; that is to say:
EIN (dBm) = 49 + Vn (dBm)
Waited value: 133 dBm
If the “A- weighted” filter is not available, a simple RC filter
will be used, that attenuates 3 dB in 15 KHz. The measured
noise will be between 5 and 7 dB above to the real one.
Signal/Noise ratio
In the same outline of the previous point, connect the
audio generator at 1 kHz / + 4 dBm to the line input.
Connect to the output an audio level meter with “A”
weighting filter and an oscilloscope. Load the output
with 600 ohms.
Move the fader to -10dB position. Adjust the line level
preset until get +4dBm output and use this value as reference for the measurement of noise. Replace the generator by a resistor of 600 ohms and measure the new
output level. This value plus + 4dBm is the S/N ratio.
This measurement result is the noise level in dBA.
Connect the audio generator (+4 dBm; 1kHz), to an left
channel of a line input. Connect an audio level meter
with “A” weighting filter, an oscilloscope and a load of
600 ohms to the left AUD output. Connect another load
of 600 ohms to the left PGM output. Select all buses
(LIN, PGM and AUD) in the module. All buses in others
modules must be out. Enable the module pressing AIR.
Move the fader to the maximum. Change the level of the
generator until obtaining +15dBm in the AUD output.
Change the position of the audio level meter from AUD
to PGM output. Verify that the audio level is +15 dBm
+/- 0,5 dB. Release the PGM button and measure the
residual level of the signal. This level, referred to +15
dBm, is the crosstalk between left audition and left program. Repeat for all the combinations of left and right
program with left and right audition. In the same way,
the crosstalk on PGM bus can be measured. Check it
with the console specifications.
