WEEE & RoHS Directives - Sonifex Statement
The Waste Electrical and Electronic Equipment (WEEE) Directive was agreed on
13 February 2003, along with the related Directive 2002/95/EC on Restrictions
of the use of certain Hazardous Substances in electrical and electronic
equipment (RoHS).
Sonifex Ltd will be happy to give you information about local organisations that can
reprocess the products, or alternatively all products that have reached “end of use” can be
returned to Sonifex and will be reprocessed correctly free of charge.
Sonifex Ltd has phased out the use of certain hazardous substances identified in the
European Union’s Restriction of Hazardous Substances (RoHS) directive. The RoHS directive
limits the use of certain hazardous substances currently used in EEE manufacture, including
lead, mercury, cadmium, hexavalent chromium, and halide-containing compounds PBB
(polybrominated biphenyl) and PBDE (polybrominated diphenyl ether). Elimination of these
substances will result in more environmentally friendly recycling of electronic equipment.
For the products which Sonifex manufacture, the main area where products were affected
was in the use of lead for manufacturing and assembling electronics circuit boards.
Sonifex Ltd practices lead-free (LF) manufacturing processes. LF solder is used on the
surface-mount PCB manufacturing processes and for hand soldering. The printed circuit
boards (PCBs) used are either gold plated, or immersion tin plated, both of which use no
lead. Historically the PCBs were hot air solder levelled (HASL) PCBs which used tin/lead
based solder.
The manufacturing processes include the assembly of purchased components from various
sources. Product is offered as RoHS compliant, or LF, only after sufficient evidence is received
from the component manufacturers that their components are RoHS compliant. Sonifex
Ltd relies solely on the distributor, or manufacturer, of the components for identification of
RoHS compliance. Thus whilst every effort is made to ensure compliance, Sonifex Ltd makes
no warranty, or certification, or declaration of compliance concerning said components.
WAR R A NT Y & S AF E T Y IN F O R MAT I O N
The Waste Electrical and Electronic Equipment Directive (WEEE) aims to minimise the
impacts of electrical and electronic equipment on the environment during their life times
and when they become waste. It applies to a huge spectrum of products. It encourages
and sets criteria for the collection, treatment, recycling and recovery of waste electrical and
electronic equipment. All products manufactured by Sonifex Ltd have the WEEE directive
label placed on the case. It gives a contact for individuals who are unsure about the correct
procedure when the product has reached its “end of use”.
Sonifex Ltd defines “Lead Free” as pertaining to any product, which has been manufactured
by Sonifex Ltd using components which have been declared by the manufacturers as
“Lead Free”. All statements by Sonifex Ltd of RoHS compliance are based on component
manufacturer documentation.

1 Introduction
S2 is a new breed of radio broadcast mixer. Using the latest technology components,
S2 offers digital audio quality with analogue reliability in a modular format. S2 has both
digital and analogue input channels, together with simultaneous analogue and digital
outputs.
INT RODU C T I O N
Following on from the Sovereign range of audio mixers, S2 combines all the features needed
of a radio broadcast mixer in a stylish, flush-mounting chassis: a wide range of input and
output channels, PFL/Cue, fader-start operation of equipment, automatic monitor muting
on mic-live, light switching remote outputs, optional EQ on input modules, gram amp input
options and 2 main audio buses, allowing you to broadcast on the PGM bus while recording
on the AUD bus, with bus output selection on each module.
Fig 1-1 : S2-15 Chassis Complete with Channels.
Innovative Design
•
The S2 chassis is available in 5 channel width sections, allowing 5, 10, 15, 20, 25
and 30 channel width mixers. This means S2 can be used for small newsrooms or
large on-air situations. The following table shows the model number along with the
total channel width.

INTRODUCTION
The Script Space (S2-7SS) occupies an area of 7 channel widths, and is designed to
hold documents / scripts for the Mixer operator when desk space is at a premium.
It is most commonly placed in the center of the mixer, although it can be positioned
anywhere within the mixer chassis. A 10 channel Script Space (S2-10SS), is
also available.
INT RODU C T ION
•
Fig 1-2 : S2-7SS Script Space.

•
Blank channels (S2-CB) can be used to fill spaces in the chassis not occupied by
active channels.
•
Modular “pop-up” input and output channels means that the mixer can be maintained
simply and quickly. Input channels can be individually removed and repaired whilst
still on-air.
•
The angle of the meterbridge can be varied and set for best viewing position.
•
Any channel can be in any position so that customizing the mixer for your own
purposes is easy.
•
Large backlit buttons allow you to see the status of the mixer at all times.
•
The fitted rear panel hides all cable connections but can be simply removed for
maintenance.
•
The modular design of the desk gives you the flexibility to expand it at a later date.
You can even add another S2 mixer and link them together with a bus connector
cable to allow for split desk configurations.

Superb Audio Quality and Unquestionable Reliability
The S2 uses the latest Crystal semiconductor technology to allow input and output of
digital audio signals up to 24 bit, 96kHz sample rate.
•
The analogue signal paths use low noise circuitry to provide superb audio
performance well capable of satisfying radio listeners worldwide.
•
The high reliability and build quality of S2 minimizes the chance of failure, avoiding
lost air-time. Each channel is individually checked twice before being assembled into
the finished chassis and the whole unit is tested before shipping.
•
ALPS long throw 100mm faders give a smooth, repeatable response and the Neutrik
XLR connectors used are an industry standard.
•
The use of VCAs controlled by the faders ensures tight stereo tracking and eliminates
mechanical and electronic noise.
•
S2 has a separate 2U power supply providing regulated, ripple-free power to
the mixer.
•
High quality stainless steel is used for the chassis and screws to prevent corrosion in
high humidity environments.

2 Installation Notes
Atmosphere
The S2 mixer should be installed in an area which is not subject to excessive heat or cold.
Also, you should avoid installing it in atmospheric conditions which are dusty, smoky, or
dirty, or where there is moisture or vibration.
I N S TA L L AT I ON NOT E S
Do not use any liquids to clean the fascia of the mixer: a soft dry brush is ideal. Use a clean
cloth moistened with water or ethyl alcohol to clean the trim and scribble pads. Other
solvents may cause damage to paint or plastic parts.
Electromagnetic Radiation
Avoid using the S2 mixer close to strong sources of electromagnetic radiation such as, video
monitors or high power electric cabling. This may cause degradation of the audio quality
due to induced voltages in connecting leads and chassis. The S2 power supply should also
be sited at least 1 metre from the mixer.
In all cases the S2 mixer and power supply should be installed and serviced by qualified
personnel.
Dimensions and Cut-Out Sizes
The S2 mixer consists of a stainless steel chassis with plastic side and top mouldings and
aluminium front trim. The dimensions for the mixer below include the mouldings and trim.
The cut-out size is for reference only and should be checked with your mixer.

Fig 2-2 : Mixer Cut-Out Details.
Channel Configuration
Each of the channels can be re-configured by jumpers, which are displayed in the “Channel
Options and Jumper Settings” section of each chapter. You should ensure that you are
thoroughly familiar with the settings available for each channel before attempting
installation of the mixer. This is because some options may involve moving jumpers on
several channels to change the configuration of the mixer.
Connectors and Cabling
Many of the problems associated with installing and maintaining a mixing console are due
to the use of poor cables or faulty connections. It is recommended that, wherever possible,
pre-wired cables are purchased from recommended manufacturers. If you need bespoke
cables making, please ensure that a qualified engineer carries out the work.

Applications
This section of the handbook provides examples of how to configure the different types of
modules for typical applications:
Controlling an On-Air Light Using the Output Modules
The On-Air light, also known as Mic Live, is used to indicate to everyone inside or outside of
the Control Room and/or Studio that microphones are live and on-air.
Shown below is an example of connecting one of the latching relay contacts on the PGM or
AUD modules to a Sonifex RB-LC3. The remote connection on the LC3 is active low.

On-Air light and Studio On-Air light respectively. See the Remote Connector pin-outs of the
relevant modules for details.
Pin 14

Control Inputs
Fig 2-12 : Using the Sonifex RB-LC3 to control an On-Air Light.
Controlling a Mic Cue Light using the Input Modules
The mic cue light is used to indicate to a guest, etc, situated in a talks studio, that they
should speak. The cue light is usually green, and there is usually one per microphone. This
should not be confused with a mic live light, which is red and there is one per studio or
control room, also known as “On Air light” (see above).
Opto-isolated outputs for a mic cue light are provided on the remote connectors of the
Mic/Mic and Mic/Line modules. See the Remote Connector pin-outs of the relevant modules
for details.
NOTE: It is vital that mains voltages are NOT connected to any of the connectors
on the mixer. If your On-Air light is to be mains operated then you should use a suitable
opto-isolated solid-state mains relay. The Sonifex Redbox RB-LC3 Light/Power controller
is a suitable unit that will control up to three On-Air lights and/or Mic cue lights.

Enabling Talkback On Mic Modules
Talkback is used for off-air communication between studios, or between the Presenter,
the Studio guests and callers on the telephone line. The presenter’s microphone module
can be configured to be the talkback source to the studio guests and telephone callers
by connecting pin 9 to pin 7 on the presenters Mic/Mic or Mic/Line modules remote
connector. This talkback audio also appears on the talkback output connector on the control
room monitor module as a continuous feed. It can be used for routing talkback to other
destinations.
Cough Switch and Talkback On Mic Modules
A cough switch is used to momentarily mute the output of a live microphone channel
when you wish to clear your throat. Closing pin 8 to pin 7 on a Mic/Mic or Mic/Line modules
remote connector performs the cough function when the module is live, i.e. when the
mic input is selected, the channel is routed, the channel is ON and the fader is up. This
function can be used for the presenters mic but is more usually only provided for the studio
microphones.
The cough switch performs the function of talkback to the presenter when the module is
not live. In this case, when a studio guest presses his cough switch the microphone module
is put in to PFL, which routes the pre fade mic signal to the control room monitoring where
it can be heard by the presenter via his headphones or monitor loudspeakers. The presenter
can talk back to the studio by using the Studio T/B button situated on the studio monitor
module. For the presenter to hear the talkback from the studio automatically, either or both
the control room monitor loudspeakers and the headphones should be set to Auto Cue/PFL.
While the Cough switch is enabled, if PGM and/or AUD are enabled then they will flash
quickly to indicate that Cough is enabled.
Using Voice Processors On Mic Channels
The Insert point on Mic input channels is useful for hooking up an outboard effects unit
to be used with the microphone, for example, a voice processor. The insert send signal
is always available as a line level balanced output. The insert return signal is enabled by
placing jumper J10 on the channel, over pins 1 & 2. The insert return function is disabled in
Line mode except when jumper J5, Mic on Line Input, is set.
Remote Start and Stop
When an input module is being used in line mode (e.g a Mic/Line on input 2 or a Dual Stereo
module) it is usually necessary to control external equipment by means of the remote start
and stop functions. See the relevant modules for pin out details.
If your equipment has a remote facility for “Fader Start” then this normally requires a
latching contact to start, opening the contact will cause the equipment to stop. In this case
it is only necessary to use the start remote, but you will need to make the contact latching
by setting a jumper (See the relevant module for jumper settings).
12
S2 User Handbook
I N S TA L L AT I O N N OT E S

If your equipment has remote facilities for “Play”, “Stop”, “Re-Cue”, it will be necessary to
use both start and stop remotes. In this case you will need a momentary start. It should be
noted that pins 2 & 5 on the input modules remote connector is common to start and stop
and should be connected to the common pins on your equipments remote connector. Pins
1 & 4 on the remote should be connected to the “Play” pins on your equipment, and pins 3 &
6 should be connected to the “Stop” pins. Sometimes it may be useful to connect the mixer
stop remote to the “Re-Cue” pin.
The jumpers J11 and J12 on the Telco channel determine which of the two true cleanfeed
busses the channel uses. There can only be a maximum of two telco channels in each mixer
and they must not share a cleanfeed bus. If you have only one telco channel, the jumpers
are fitted over pins 1 & 2 of J11, using cleanfeed bus 1. If a second telco channel is present in
the mixer, then this second channel will have the jumpers fitted over pins 2 & 3 of J12, using
cleanfeed bus 2 only.
INSTA L L AT I O N NOT E S
Adding Telco Channels
When adding a Telco channel to the mixer there are certain requirements that need to be
met for the correct operation of the cleanfeed busses. Depending on whether you have 1,
2 or no telco channels fitted, you may have to alter the cleanfeed bus termination on the
digital PGM and AUD Output channels. If the console is supplied without Telco channels
then both cleanfeed mix busses will need to be terminated. With one Telco channel, only
the unused cleanfeed bus will require termination. With two Telco channels no termination
is required. Please refer to that section of the handbook for further info.
Removing & Replacing Channels
When installing the mixer it may be necessary to change certain characteristics of a channel
to suit your specific needs, e.g. jumper settings, internal gain pots, etc. To do this the channel
must be removed from the chassis to gain access to the jumpers and pots. Particular care
must be taken when performing this procedure.
To remove a channel, first disconnect any attached cables from the rear of the channel, and
remove the two screws from the front panel of the channel. The channel should now be
lifted slightly from the chassis with the aid of springs situated at the two fixing points, with
enough room to grab both ends of the channel, so that you can carefully lift it from the
chassis. Be careful not to lay the channel across the mixer, as the underside of the channel
PCB may cause scratching.
Once the necessary changes have been made, ensure that the main bus cable is still firmly
attached and carefully position the channel directly above the space where it was removed
from, holding it at a tilt, so that the fader end of the mixer will make contact with the
chassis first. Slowly lower it down into the mixer, making sure that the main bus cable is
formed correctly and the slack does not get trapped beneath the channel. Once the fader
end has made contact, continue lowering the rear end of the channel down until that also
makes contact, ensuring that it is flush with the channels beside it. Replace the screws, and
reattach the cables to the rear of the channel.

Connecting A Split Desk
I N S TA L L AT I ON NOT E S
There are three cables used when connecting an S2 mixer split desk configuration. A 16
way IDC cable which connects the two meterbridge distribution boards, A 60 way jacketed
IDC cable which connects the two main mixer bus cables and an earth braid cable which
connects the two chassis’. When shipped, these three cables will already be attached to
one of the mixers and will require attaching to the other mixer. The procedure to do this is
described below.
Connecting The Mixer Bus Interconnect Cable
On the under side of the mixer chassis are two slots at each end. These are where the
mixer bus interconnect cable feeds through (Fig 2-13). The first thing to do is to remove
the channel from the end of the mixer where the cable is going to be connected. If the
interconnect cable is to be connected to the left handside mixer then this will be the
right most channel of the mixer. If the interconnect cable is to be connected to the right
handside mixer then this will be the left most channel.
Fig 2-13 : Mixer Bus Cable Slots.
Once the channel has been removed,
pull the cable through the slot making
sure that the cable has not twisted
coming from the first mixer. Pull it
through so that about 2 inches (5 cm) of
the cable jacketing is inside the chassis.
Connect the screening wire to one of
the clamping plate screws and screw in
the plate to the underside of the chassis
to secure the cable, and stop it from
moving (Fig 2-14).
Fig 2-14 : Mixer Bus Cable Screen Connection.

Then loop the cable back over itself and connect the 60 way IDC plug to the main mixer bus
(Fig 2-15). Now reconnect the channel that was removed, to the free 60 way IDC socket,
using the procedure described on page 13 for removing and replacing channels.
Connecting The Meterbridge Interconnect Cable
To connect this cable some of the panels on the meterbridge will require removing to locate
the meterbridge distribution board. Once located, find the IDC header labelled on the
distribution PCB as “From Output Module”. At the back of the mixer chassis there is a slot
just above where the output modules sit. Feed the Meterbridge Interconnect cable through
the slot and plug it into the header. Once this has been done, replace the meterbridge
panels that were removed earlier to locate the distribution board.

Fig 2-16 : Meterbridge Interconnection.
Connecting The Earth Braid
As with the other cables, this will already be connected to one of the split desks. Simply
connect the other end of the cable to the other desk, by unscrewing the outer M4 nut and
removing the shakeproof washer. Then place the solder tag of the earth braid cable on the
bolt and then replacing the shakeproof and M4 nut.

3 Power Supply
S2-PSU Power Supply
POW ER S U PPLY
Each S2 is shipped with a separate power supply in protective packaging and should be
inspected for damage before use. Where an item is found to have transit damage, notify the
carrier immediately with all the relevant details of the shipment. Packing materials should
be kept for inspection.
Fig 3-1 : S2-PSU Front Panel.
Front Panel
The S2-PSU is a 2U high rack-mount unit, which can supply power to the entire range of S2
mixers. A lead with a special 9 pin D-Type socket (see Fig 2-9) on each end is used to connect
the power supply to the mixer.
The power supply should be installed where there is adequate ventilation for heat to
circulate from the rear of the unit. The mixer has a heat sink attached to the rear panel,
which radiates some heat.
Four LED’s on the front of the unit indicate whether the power to the four voltage rails is
being supplied correctly. If one of the LED’s fails, then there is a problem with the power
supply unit.

Rear Panel
It is important to connect the mains supply in accordance with the information given.
Ensure that the rear panel mains voltage statement on the separate power supply indicates
that your equipment is suitable for your mains supply voltage and that the mains supply
fuse is correctly rated. The fuse as supplied is correct for the voltage setting.
Safety of Mains Operated Equipment
This equipment has been designed to meet the safety regulations currently advised
in the country of purchase and it conforms to the safety regulations specified by
use of the CE Mark.
This equipment will operate in a horizontal position.
WARNING: The power must be switched off at the supply or the power lead must be
disconnected before attempting to remove the panels or cover. Removal of the panels
and cover can expose dangerous voltages. The cover is connected to the chassis ground
of the equipment by means of fixing screws. It is essential to maintain this earth-ground
connection to maintain a safe operating environment.
POWE R S U PPLY
The power cable supplied carries an EARTH conductor, which is connected internally to the
equipment chassis ground. This connection through a properly wired power Connector
is essential for safe operation. Disconnection of this earth connection may render the
Equipment unsafe, with a consequential possible electrical shock hazard from exposed
metallic parts.
In addition, to provide an Electromagnetic Shield, contact between the cover and the
chassis must be maintained when in use.
The power supply is switchable between 230V & 115V.
Warning: There are no user serviceably parts inside the machine. If you should ever
need to look inside the unit, always disconnect the mains supply before removing the
equipment covers.
The rear panel of the equipment carries the Serial Number of the machine. The operating
voltage of the S2 power supply is selectable at the fuse carrier on the power inlet port of
the S2-PSU unit. Ensure that the machine operating voltage is correct for your mains power
supply.
The safety specification of your S2 power supply complies with local requirements and must
be earthed through the mains connector.

S2-PSUS Dual Power Supply Switcher
POW ER S U PPLY
The S2-PSUS is a passive power switcher which takes the power feeds from 2 x S2-PSU units
and switches between them in the event of failure. Two trailing leads 0.5m in length connect
to 2 x S2-PSU units. With LED failure indicators and GPI alarms, the S2-PSUS is the perfect
dual redundant power supply module.
Fig 3-3 : S2-PSUS Front Panel.
Front Panel
As an intelligent unit, the PSUS detects changes in the DC levels supplied to the S2. A
failure in any one of the power rails, defined by calibrated limits, results in switching to the
secondary power unit.
Two indicator LEDs on the front of the unit are used to display which power supply is current
supplying the mixer. There are also eight LEDs that display the status for each of the rails.
The LED will stay illuminated when the rail is stable. If the LED flashes quickly, then the level
is too high on that rail or if the LED flashes slowly, then the level is too low on that
particular rail.
Fig 3-4 : S2-PSUS Rear Panel.
Rear Panel
There are alarm outputs on the rear of the unit, created using opto-isolator switches.
These alarm outputs mimic those on the front panel and there is also an alarm relay which
operates as a warning for total unit failure. This will come on if the both power supplies
have failed.

INPUT CHANNELS
4 Input Channels
There are eleven different input channels available for installation in the mixer as well as a
blank channel and script space.
The channels are each covered in the following chapters, but a summary follows:
I NPU T CHA N N E LS
S2-CML Mic/Line Input Channel
The Mic/Line Input channel is a mono input with a button switch to select either Mic or
Mono Line. If the Mic input is used for the presenter’s mic it can also become the talkback
mic. The talkback function will be retained when the channel input is switched to Line.
Equalisation is fitted as standard on this channel and is enabled by the EQ button, providing
7dB cut and boost at HF (6.5kHz) and LF (100Hz). The Mic input has a jumper selectable high
pass filter to remove low frequency intrusions. A Pan control is available to facilitate stereo
imaging. A balanced line level insert send and return is available for the Mic input but is
disabled in Line mode.
Channel coarse gain is set by internal presets for mic and line – fine gain is trimmed by the

Selecting the PGM, AUD buttons routes the channel audio output to the PGM
and/or AUD mix busses. The buttons are illuminated in green to indicate the
routing status. Changing the status of the PGM button is inhibited when the
channel is “live”.
Equalisation Controls
The HF and LF controls are used to adjust the equalisation of the signal. The
HF control boosts and cuts the signal by ±7dB at 6.5kHz. The LF control boosts
and cuts the signal by ±7dB at 100Hz. The EQ button places the equalisation
in and out of the signal path. The button is illuminated in yellow when the EQ
is active.
TRIM Control
The Trim control provides an additional ±12dB of gain to fine tune the input
signal level.
BAL/PAN Control
The Bal control is used to pan the mono input signal in the stereo image.
Full anti-clockwise pans the signal to the left and increases the signal by 3dB
(right channel reduces by 70dB); full clockwise pans the signal to the right
and increases the signal by 3dB (left channel reduces by 70dB).
CUE/PFL Selection
Selecting the CUE/PFL button routes the pre-fader input signal to the
monitoring system where the signal can be heard via headphones and/or
loudspeakers. The level may be checked on meters and adjusted via the TRIM
control and panned via the BAL/PAN control. The button is illuminated in
green when CUE/PFL is active. There is a jumper option to cancel the CUE/PFL

Remote for Mic Cue Light
The remote output for the Microphone input (Input 1) can be used to operate a Mic Cue
light when the channel is ON and the fader is up. This should not be confused with a Mic
Live light. The Mic Cue light is used for indicating to presenter or guest that they should
talk into the microphone. Jumper J1 is placed over pins 1 & 2. This is the default setting and
produces a latched remote output.
Remote for Line
The remote output for the Line input (Input 2) can be used for starting a machine such as
a CD or MD player. The default setting produces a momentary remote output. If a latched
output is required then a jumper should be placed over pins 1 & 2 of J2. The remote stop
output for the Line input is always momentary.
Continuous Momentary Start
The continuous momentary start function is rarely used on the Mic/Line channel and
therefore J3 should be left in the default setting.
CUE/PFL Cancel
The CUE/PFL function is normally an alternate action. Press the button to select and press
again to de-select. However it may be desirable to have the fader up signal cancel a Cue/PFL
selection. Placing a jumper over J4 pins 1 & 2 will enable a previously selected Cue/PFL
function to be cancelled when the fader is up and the channel is ON. The default setting is
none (not fitted).
S2-CML MIC/LINE CHANNEL WITH EQ
Fig 5-1 : S2 Mic/Line Input Board Layout.
Mic on Line Input
In certain circumstances the microphone signal may be at line level, for instance, when used
with an external pre-amp or effects unit. The microphone can therefore be placed on the
line input but will require the control room or studio muting function to be enabled. Placing
jumper J5 over pins 1 & 2 will enable the muting functions on the line input. The default
setting is none (not fitted).
S2 User Handbook

S2-CML MIC/LINE CHANNEL WITH EQ
S2-CML MIC/LINE CHANNEL WITH EQ
Phantom Power
If you will be using a phantom powered microphone, jumper J6 must be placed over pins 1
& 2. If a normal microphone is used the jumper should be left over pins 2 & 3. With phantom
power selected a voltage of +48V is applied to pins 2 & 3 of the XLR connector. The voltage
is applied through 6k8 resistors limiting the current to 14mA. The default setting is with the
jumper over pins 2 & 3.
Microphone LF Response
The default setting of J7 is with the jumper over pins 1 & 2 which gives a full LF response to
the microphone. However, if your studio is acoustically poor and suffers from a lot of low
frequency rumbles the LF response of the microphone can be rolled off at 125kHz, 6dB
per octave, to reduce these acoustic problems. This is achieved by removing jumper J7.
Jumpers J8 and J9 are not fitted to the Mic/Line channel.
Enabling the Insert Point
The Insert point is useful for hooking up an outboard effects unit to be used with the
microphone, for example, a voice processor. The insert send signal is always available as a
line level balanced output. The insert return signal is enabled by placing jumper J10 over
pins 1 & 2. The insert return function is disabled in Line mode except when jumper J5, Mic
on Line Input, is set. The default setting of J10 is none (not fitted).
Jumpers J11 and J12 are not fitted to the Mic/line channel.
Mic Live Muting
The microphone input can be set to mute the control room or studio monitors. The default
setting of J13 over pins 1 & 2 will enable a live microphone to mute the control room
monitors. If it is required to mute the studio monitors the jumper should be shifted to pins
2 & 3. If no muting is required, the jumper should be removed. When a line level mic is used
on input 2, J15 sets the muting function. A jumper over pins 1 & 2 will mute the control
room monitors and over pins 2 & 3 will mute the studio monitors. Line input (input 2)
muting is only enabled when jumper J5, Mic on Line Input, is set. The default setting of J15
is none (not fitted).
Timer Auto Start
The dual timer in the meterbridge can be set to start automatically from a fader open/
channel On signal. Jumper J14 determines which timer is set to auto-start. A jumper over
pins 1 & 2 will start Timer 1, shifting the jumper to pins 2 & 3 will start Timer 2. The default
setting of J14 is none (not fitted).
Presets
Two presets are available for adjustment of the input gain for the mic and line levels. The
mic preset, P1, provides 59dB of gain adjustment, allowing an input range of –7dB to –66dB.
The preset should be adjusted to give 0dB output for the chosen microphone in use. The
level is preset for –50dB input when shipped.
The line preset, P3, provides 16dB of gain adjustment, allowing an input range of +6dB to
–10dB referenced to 0dB output. The preset should be adjusted to give 0dB output for the

chosen source, and will cater for professional equipment with nominal output levels up to
+4dB and non-professional equipment with nominal output levels down to –10dBV. The
level is preset for 0dB input when shipped.
Presets P5 & P6 are for altering the audio waveform symmetry (i.e. distortion). They are
factory set on final test and should not be adjusted further.
A third preset, P9, sets the VCA fader gain to 0dB when the fader is fully open. This is preset
on final test and should not require further adjustment, unless it has been found necessary
to replace the fader or other VCA components.

power selected a voltage of +48V is applied to pins 2 & 3 of the XLR connector. The voltage
is applied through 6k8 resistors limiting the current to 14mA. The default setting is with the
jumper over pins 2 & 3.

Mic 1 LF Response
The default setting of J7 is with the jumper over pins 1 & 2 which gives a full LF response to
the microphone. However, if your studio is acoustically poor and suffers from a lot of low
frequency rumbles the LF response of the microphone can be rolled off, at 125kHz, 6dB per
octave, to reduce these acoustic problems. This is achieved by removing jumper J7.
Mic 2 LF Response
The default setting of J9 is with the jumper over pins 1 & 2 which gives a full LF response to
the microphone. However, if your studio is acoustically poor and suffers from a lot of low
frequency rumbles the LF response of the microphone can be rolled off, at 125kHz, 6dB per
octave, to reduce these acoustic problems. This is achieved by removing jumper J9.
Enabling the Insert Point
The Insert point is useful for hooking up an outboard effects unit to be used with the
microphone. The insert send signal is always available as a line level balanced output. The
insert return signal is enabled by placing jumper J10 over pins 1 & 2. The default setting of
J10 is none (not fitted).
Jumpers J11 and J12 are not fitted to the Mic/Mic channel.
Mic Live Muting
The microphone inputs can be set to mute the control room or studio monitors. The default
setting of J13 over pins 1 & 2 will enable a live microphone on Mic 1 input to mute the
control room monitors. If it is required to mute the studio monitors the jumper should be
shifted to pins 2 & 3. If no muting is required, the jumper should be removed. Similarly, J15
sets the muting function for the microphone on Mic 2 input. A jumper over pins 1 & 2 will
mute the control room monitors and over pins 2 & 3 will mute the studio monitors. The
default setting of J15 is none (not fitted).

Phantom Power Mic 2
If you will be using a phantom powered microphone, jumper J8 must be placed over pins 1
& 2. If a normal microphone is used the jumper should be left over pins 2 & 3. With phantom
power selected a voltage of +48V is applied to pins 2 & 3 of the XLR connector. The voltage
is applied through 6k8 resistors limiting the current to 14mA. The default setting is with the
jumper over pins 2 & 3.
Presets
Two presets are available for adjustment of the input gain for mic 1 and mic 2 levels. Mic
1 preset, P1, and Mic 2 preset, P2, provide 59dB of gain adjustment, allowing an input
range of –7dB to –66dB. The presets should be adjusted to give 0dB output for the chosen
microphones in use. The level is preset for –50dB input when shipped.
Presets P5 & P6 are for altering the audio waveform symmetry (i.e. distortion). They are factory
set on final test and should not be adjusted further.
A third preset, P9, sets the VCA fader gain to 0dB when the fader is fully open. This is preset
on final test and should not require further adjustment, unless it has been found necessary
to replace the fader or other VCA components.

Continuous Momentary Start
The continuous momentary start function can be used for equipment that only ever
requires a remote start but not a stop. Placing a jumper over J3 pins 1 & 2 enables the
function. When enabled the operation of the ON button is changed to a continuous start
button. With the fader down, the button shows red. With the fader up, the button shows
green and each press of the ON button will trigger a momentary start from the remote
contacts. The default setting for J3 is none (not fitted). It is not possible to configure a
latching remote start output when the continuous momentary start option has been
selected.
CUE/PFL Cancel
The CUE/PFL function is normally an alternate action. Press the button to select and press
again to de-select. However it may be desirable to have the fader up signal cancel a CUE/PFL
selection. Placing a jumper over J4 pins 1 & 2 will enable a previously selected CUE/PFL
function to be cancelled when the fader is up and the channel is ON. The default setting is
none (not fitted).
Jumper J5 is not fitted to this channel.
Timer Auto Start
The dual timer in the meterbridge can be set to start automatically from a fader open/
channel On signal. Jumper J6 determines which timer is set to auto-start. A jumper over pins
1 & 2 will start Timer 1, shifting the jumper to pins 2 & 3 will start Timer 2. The default setting
of J6 is none (not fitted).
Jumpers J7 to J10 are not fitted to this channel.
Presets
Four presets are available for adjustment of the input gain, left and right, for the two line
inputs. Presets, P1 (left), P2 (right) adjust the levels for Line input 1 and P3 (left), P4 (right)
for Line input 2. They provide 16dB of gain adjustment, allowing an input range of +6dB to
–10dB referenced to 0dB output. The presets should be adjusted to give 0dB output for the
chosen source, and will cater for professional equipment with nominal output levels up to
+4dB and non-professional equipment with nominal output levels down to –10dBV. The
levels are preset for 0dB input when shipped.

Presets P15 & P16 are for altering the audio waveform symmetry (i.e. distortion). They are
factory set on final test and should not be adjusted further.
A seventh preset, P17, sets the VCA fader gain to 0dB when the fader is fully open. This is
preset on final test and should not require further adjustment, unless it has been found
necessary to replace the fader or other VCA components.
The setup procedure for configuring the pins is described in the following steps. Since the
settings are stored in non-volatile RAM, this only needs to be done once.
•
To initiate setup, press and hold down the PGM button while pressing the AUD button
five times. Once completed, all the buttons will turn off and after a short while will
display the current setting for GPIO 1’s function (pin 8 on the remote connector).
•
Using the PGM button, cycle through the following options (shown in the table
below) until the desired setting is selected. For example to set GPIO 1 to a latching,
active high input, press the PGM button until only the CUE/PFL button is illuminated
ON. This setting is then applied by pressing the ON button. The PGM button will flash
quickly for about a second to indicate that the setting is stored.

S2-CSGE/S2-CSG STEREO LINE AND
GRAM CHANNEL WITH & WITHOUT EQ
The RIAA Gram input level (Input 2) is fixed.
Presets P15 & P16 are for altering the audio waveform symmetry (i.e. distortion). They are
factory set on final test and should not be adjusted further.
S2-CSGE/S2-CSG STEREO LINE AND
GRAM CHANNEL WITH & WITHOUT EQ
A fifth preset, P17, sets the VCA fader gain to 0dB when the fader is fully open. This is preset
on final test and should not require further adjustment, unless it has been found necessary
to replace the fader or other VCA components.
General Purpose I/O
Two I/O pins are available on the remotes connector that can be configured for general
purpose use. Currently they can be used to either turn the channel on and off remotely or
used as an indication for when the channel is live. They are completely configurable and
can be set as inputs or outputs, latching or momentary and active high or active low.
The setup procedure for configuring the pins is described in the following steps. Since the
settings are stored in non-volatile RAM, this only needs to be done once.
•
To initiate setup, press and hold down the PGM button while pressing the AUD button
five times. Once completed, all the buttons will turn off and after a short while will
display the current setting for GPIO 1’s function (pin 8 on the remote connector).
•
Using the PGM button, cycle through the following options (shown in the table
below) until the desired setting is selected. For example to set GPIO 1 to a latching,
active high input, press the PGM button until only the CUE/PFL button is illuminated
ON. This setting is then applied by pressing the ON button. The PGM button will flash
quickly for about a second to indicate that the setting is stored.

PGM and AUD Selection
Selecting the PGM, AUD buttons routes the channel
analogue audio output to the PGM and/or AUD mix busses.
The buttons illuminate green to indicate the routing status.
Changing the status of the PGM button is inhibited for a
“live” channel.
INP 1/INP 2 Selection
Selecting the INP 1/INP 2 button changes the channel input
connection between Input 1 and Input 2. The digital inputs
can be configured by internal jumpers to be either AES/
EBUor S/PDIF. The button is illuminated in red to indicate
when Input 2 is selected. The operation of the button is
inhibited for a “live” channel.
Equalisation Controls (S2-CDSE only)
The HF and LF controls are used to adjust the equalisation of
the signal. The HF control boosts and cuts the signal by
± 7dB at 6.5kHz. The LF control boosts and cuts the signal by
±7dB at 100Hz. The EQ button places the equalisation in and
out of the signal path. The button is illuminated in yellow
when the EQ is active.
TRIM Control
The TRIM pot provides an additional ±12dB of gain to fine
tune the input level.
BAL/PAN Control
The BAL/PAN control is used to balance the stereo image.
Full anti-clockwise shifts the signal to the left and increases
the signal by 6dB (right channel reduces by 6dB); full
clockwise shifts the signal to the right and increases the
signal by 6dB (left channel reduces by 6dB).
CUE/PFL Selection
Selecting the CUE/PFL button routes the pre-fader input
signal to the monitoring system where the signal can be
heard via headphones and/or loudspeakers. The level may
be checked on meters and adjusted via the Trim control and
balanced via the Bal control. The button is illuminated in
green when CUE/PFL is active. There is a jumper option to
cancel the CUE/PFL selection when the fader is raised.

The 100mm VCA fader provides unity gain when fully open. The channel input signal is
routed to the outputs whenever the fader is open, the ON button is selected and either or
both of the routing buttons are selected.
The illumination in this case toggles between unlit, channel OFF and green, channel ON.

The ON button works in conjunction with the fader and is used to control channel remotes,
routing, timers, etc. The button shows various states. When unlit the channel is off. Flashing
green indicates that there is no valid digital input. Flashing red indicates that the channel
has been selected to ON but remains unrouted i.e. neither PGM or AUD is selected. Flashing
red and green indicates that both of the above states are valid. Steady red indicates that the
channel is ON and “armed”, ready for the fader to be raised. Raising the fader changes the
illumination to green indicating that the channel is live. Alternatively, with the button unlit
the fader may be raised and the channel can be operated simply by selecting ON.

Remote for Digital Input 1
The remote output for Input 1 can be used for a start and stop function wired to other
studio equipment such as CD or MD players. The default setting for J1 is none (not fitted),
which produces a momentary remote contact. If your equipment requires a latching contact
for remote start then a jumper should be placed over pins 1 & 2 of J1. The remote stop for
Input 1 is always momentary.
Remote for Digital Input 2
The remote output for Input 2 can be used for a start and stop function wired to other
studio equipment such as CD or MD players. The default setting for J2 is none (not fitted),
which produces a momentary remote contact. If your equipment requires a latching contact
for remote start then a jumper should be placed over pins 1 & 2 of J2. The remote stop for
Input 2 is always momentary.
Continuous Momentary Start
The continuous momentary start function can be used for equipment that only ever
requires a remote start but not a stop. Placing a jumper over J3 pins 1 & 2 enables the
function. When enabled the operation of the ON button is changed to a continuous start
button. With the fader down, the button shows red. With the fader up, the button shows
green and each press of the ON button will trigger a momentary start from the remote
contacts. The default setting for J3 is none (not fitted). It is not possible to configure a
latching remote start output when the continuous momentary start option has been
selected.
CUE/PFL Cancel
The CUE/PFL function is normally an alternate action. Press the button to select and press
again to de-select. However it may be desirable to have the fader up signal cancel a CUE/PFL
selection. Placing a jumper over J4 pins 1 & 2 will enable a previously selected CUE/PFL
function to be cancelled when the fader is up and the channel is ON. The default setting is
none (not fitted).
De-emphasis
Placing a jumper over pins 1 & 2 of J3 will decode 50/15µs emphasis when indicated by
certain channel status bits in the incoming digital audio data.
Disabling PFL When no Input is Detected
When J11 is fitted, if a digital input is not detected on the selected input, then PFL is
disabled/muted.
Timer Auto Start
The dual timer in the meterbridge can be set to start automatically from a fader open/
channel On signal. Jumper J6 determines which timer is set to auto-start. A jumper over pins
1 & 2 will start Timer 1, shifting the jumper to pins 2 & 3 will start Timer 2. The default setting
of J6 is none (not fitted).
Jumpers J7 to J10 are not fitted to this channel.

AES/EBU, S/PDIF Select for Input 1
Input 1 can be either balanced AES/EBU or unbalanced S/PDIF. The default setting for J7,
pins 1 & 2, is AES/EBU input via XLRs. Shifting the jumper to pins 2 & 3 enables the S/PDIF
input on phonos.
AES/EBU, S/PDIF Select for Input 2
Input 2 can be either balanced AES/EBU or unbalanced S/PDIF. The default setting for J8,
pins 1 & 2, is AES/EBU input via XLRs. Shifting the jumper to pins 2 & 3 enables the S/PDIF
input on phonos.
Presets P15 & P16 are for altering the audio waveform symmetry (i.e. distortion). They are
factory set on final test and should not be adjusted further.
A fifth preset, P17, sets the VCA fader gain to 0dB when the fader is fully open. This is preset
on final test and should not require further adjustment, unless it has been found necessary
to replace the fader or other VCA components.
General Purpose I/O
Two I/O pins are available on the remotes connector that can be configured for general
purpose use. Currently they can be used to either turn the channel on and off remotely or
used as an indication for when the channel is live. They are completely configurable and
can be set as inputs or outputs, latching or momentary and active high or active low.
The setup procedure for configuring the pins is described in the following steps. Since the
settings are stored in non-volatile RAM, this only needs to be done once.
•
To initiate setup, press and hold down the PGM button while pressing the AUD button
five times. Once completed, all the buttons will turn off and after a short while will
display the current setting for GPIO 1’s function (pin 8 on the remote connector).
•
Using the PGM button, cycle through the following options (shown in the table
below) until the desired setting is selected. For example to set GPIO 1 to a latching,
active high input, press the PGM button until only the CUE/PFL button is illuminated
ON. This setting is then applied by pressing the ON button. The PGM button will flash
quickly for about a second to indicate that the setting is stored.

always momentary. It is not possible to configure a latching remote start output when the
continuous momentary start option has been selected.
Presets
Two presets are available for adjustment of the input gain, left and right, for all six line
inputs. Presets, P1 (left), P2 (right) provide 16dB of gain adjustment, allowing an input
range of +6dB to –10dB referenced to 0dB output. The presets should be adjusted to give
0dB output for the chosen source, and will cater for professional equipment with nominal
output levels up to +4dB and non-professional equipment with nominal output levels down
to –10dBV. The levels are preset for 0dB input when shipped.
A third preset, P5, sets the VCA fader gain to 0dB when the fader is fully open. This is preset
on final test and should not require further adjustment, unless it has been found necessary
to replace the fader or other VCA components.
Presets P3 & P4 are for altering the audio waveform symmetry (i.e. distortion). They are
factory set on final test and should not be adjusted further.

PGM and AUD Selection
Selecting the PGM, AUD buttons routes the channel audio output to
the PGM and/or AUD mix busses. The buttons are illuminated in green
to indicate the routing status. Changing the status of the PGM button is
inhibited when the channel is “live”. Selecting the PGM button also routes the
channel to one of the two true cleanfeed busses. When selecting the AUD
button only, a cleanfeed is generated via the channel mix-minus system.
When both PGM and AUD are selected the channel operates in the true
cleanfeed mode, sending the PGM signal to the cleanfeed bus.
Equalisation Controls
The HF and LF controls are used to adjust the equalisation of the signal. The
HF control boosts and cuts the signal by ± 7dB at 6.5kHz. The LF control
boosts and cuts the signal by ± 7dB at 100Hz. The EQ button places the
equalisation in and out of the signal path. The button is illuminated in yellow
when the EQ is active.
TRIM control
The TRIM control provides an additional ± 12dB of gain to fine tune the input
signal level.
BAL/PAN Control
The BAL/PAN control is used to pan the mono input signal in the stereo
image. Full anti-clockwise pans the signal to the left and increases the signal
by 3dB (right channel reduces by 70dB); full clockwise pans the signal to the
right and increases the signal by 3dB (left channel reduces by 70dB).
CUE/PFL & T/B Selection
Selecting the CUE/PFL & T/B button routes the pre-fader input signal to the
monitoring system where the signal can be heard via headphones and/or
loudspeakers. The level may be checked on meters and adjusted via the TRIM
control and panned via the BAL/PAN control. In addition, talkback is routed
back to the caller via the cleanfeed system. This enables the presenter/
technical operator to communicate with the caller prior to putting the caller
live to air. The button is illuminated in green when CUE/PFL is active. There
is a jumper option to cancel the CUE/PFL selection when the fader is raised.
This button works with both a momentary and latched operation. If held
down, the selection is cancelled when released, otherwise the button is
alternate action.

Fader
The 100mm VCA fader provides unity gain when fully open. The channel

changes the illumination to green indicating that the channel is live. Alternatively, with the
button unlit the fader may be raised and the channel can be operated simply by selecting
LINE HOLD button (Note though that this will cause dial tone and the dialling of the call to

Remote for Hybrid Hold
The remote output of the Telco channel can be used to hold the line on a telephone hybrid
when the channel is ON and the fader is up. The hybrid is also put on hold when the Cue/
PFL & T/B button is selected. Jumper J1 is placed over pins 1 & 2. This is the default setting
and produces a latched remote output. If your hybrid requires a momentary contact then
shift the jumper to pins 2 & 3.
Jumpers J2 and J3 are not fitted to the Telco channel.
CUE/PFL & T/B Cancel
The CUE/PFL & T/B function is normally an alternate action. Press the button to select and
press again to de-select. However it may be desirable to have the fader up signal cancel a
CUE/PFL & T/B selection. Placing a jumper over J4 pins 1 & 2 will enable a previously selected
CUE/PFL & T/B function to be cancelled when the fader is up and the channel is ON. The
default setting is none (not fitted).

Cleanfeed Bus Output Select
The jumpers J11 and J12 determine which of the two true cleanfeed busses the channel
uses. There can only be a maximum of two telco channels in each mixer and they must not
share a cleanfeed bus. If you have only one telco channel, the jumpers are fitted over pins
1 & 2 of J11, using cleanfeed 1. If a second telco channel is present in the mixer, then this
second channel will have the jumpers fitted over pins 2 & 3 of J12, using cleanfeed 2 only.
Presets
The line input preset, P3, provides 16dB of gain adjustment, allowing an input range of
+6dB to –10dB referenced to 0dB output. The preset should be adjusted to give 0dB output
for the chosen telephone hybrid, and will cater for professional equipment with nominal
output levels up to +4dB and non-professional equipment with nominal output levels down
to –10dBV. The level is preset for 0dB input when shipped.

use. The level is preset for 0dB output when shipped.
Presets P5 & P6 are for altering the audio waveform symmetry (i.e. distortion). They are
factory set on final test and should not be adjusted further.
S 2 - C T T E LCO C H A N N E L W I T H E Q
Two presets are used to set up the cleanfeed mix-minus null when the channel is routed to
AUD only. With the channel routed to AUD only and a signal of 1kHz applied to the input
and adjusted to register 0dB on the console output, P7 (left) and P8 (right) are adjusted for
minimum signal at the cleanfeed output connector.
68
A further preset, P9, sets the VCA fader gain to 0dB when the fader is fully open. This is
preset on final test and should not require further adjustment, unless it has been found
necessary to replace the fader or other VCA components.
Terminating The Cleanfeed Busses
Depending on whether you have 1, 2 or no telco channels fitted, you may have to alter the
cleanfeed bus termination on the digital PGM and AUD Output channels. Please refer to

Remote for Line Input
The remote output for the Line input can be used for a start and stop function wired to
other studio equipment such as CD or MD players. The default setting for J1 is none (not
fitted), which produces a momentary remote contact. If your equipment requires a latching
contact for remote start then a jumper should be placed over pins 1 & 2 of J1. The remote
stop is always momentary.
CUE/PFL Cancel
The CUE/PFL function is normally an alternate action. Press the button to select and press
again to de-select. However it may be desirable to have the fader up signal cancel a CUE/PFL
selection. Placing a jumper over J4 pins 1 & 2 will enable a previously selected CUE/PFL
function to be cancelled when the fader is up and the channel is ON. The default setting is
none (not fitted).
Jumper J5 is not fitted to this channel.
Timer Auto Start
The dual timer in the meterbridge can be set to start automatically from a fader open/
channel On signal. Jumper J6 determines which timer is set to auto-start. A jumper over pins
1 & 2 will start Timer 1, shifting the jumper to pins 2 & 3 will start Timer 2. The default setting
of J6 is none (not fitted).
Jumpers J7 and J8 are not fitted to this channel.
Cleanfeed Output Selection
The default setting for jumpers J9 and J10 is over pins 1 & 2 which gives stereo cleanfeed
outputs. There may be a situation where only mono cleanfeed is required with a continuous
feed of talkback from the studio. Placing jumper J9 over pins 2 & 3 places mono cleanfeed
on the left cleanfeed output and placing jumper J10 over pins 2 & 3 places the continuous
talkback feed on the right cleanfeed output.
S2-CSMM STEREO MIX MINUS CHANNEL WITH EQ
Continuous Momentary Start
The continuous momentary start function can be used for equipment that only ever
requires a remote start but not a stop. Placing a jumper over J3 pins 1 & 2 enables the
function. When enabled the operation of the ON button is changed to a continuous start
button. With the fader down, the button shows red. With the fader up, the button shows
green and each press of the ON button will trigger a momentary start from the remote
contacts. The default setting for J3 is none (not fitted). It is not possible to configure a
latching remote start output when the continuous momentary start option has been
selected.

Change the routing to AUD only and repeat the set up using presets P9, P10 at 1kHz and
P11, P12 at 100Hz. This will be set up during final test and should not require further
adjustment, unless the channel position changes within the frame when minor adjustment
may be required to maintain best performance.

Two presets are available for adjustment of the Cleanfeed gain, left and right. The presets
P13 (left), P14 (right) should be adjusted to give 0dB output for the chosen source.
Presets P15 & P16 are for altering the audio waveform symmetry (i.e. distortion). They are
factory set on final test and should not be adjusted further.
A further preset, P17, sets the VCA fader gain to 0dB when the fader is fully open. This is
preset on final test and should not require further adjustment, unless it has been found
necessary to replace the fader or other VCA components.
General Purpose I/O
Two I/O pins are available on the remotes connector that can be configured for general
purpose use. Currently they can be used to either turn the channel on and off, indicate
when the channel is live, or control Talkback enable. They are completely configurable and
can be set as inputs or outputs, latching or momentary and active high or active low.
The setup procedure for configuring the pins is described in the following steps. Since the
settings are stored in non-volatile RAM, this only needs to be done once.
•
To initiate setup, press and hold down the PGM button while pressing the AUD button
five times. Once completed, all the buttons will turn off and after a short while will
display the current setting for GPIO 1’s function (pin 8 on the remote connector).
•
Using the PGM button, cycle through the following options (shown in the table
below) until the desired setting is selected. For example to set GPIO 1 to a latching,
active high input, press the PGM button until only the CUE/PFL button is illuminated
ON. This setting is then applied by pressing the ON button. The PGM button will flash
quickly for about a second to indicate that the setting is stored.

OUTPUT CHANNELS
13 Output Channels
There are six different output channels, available for installation in the mixer as well as a
blank channel and script space. The channels are each covered in the following chapters,
but a summary follows:
OU T PU T CH A N N E LS
S2-ODP Digital PGM Output Channel &
S2-ODPF Digital PGM Output Channel With Master Fader
This channel is common to every mixer and provides a digital and analogue stereo output
from the PGM mix bus and a mono analogue output. The digital output is available as a
balanced AES/EBU signal via standard XLRs or as S/PDIF on phono sockets. The sample
rate can be set automatically or by internal jumpers from 32 kHz to 96 kHz and the output
sample size from 16 to 24 bits. The balanced analogue PGM output and mono output is
available on a 15 way D type connector.
Button switches at the top of the channel select the mono output source. The S2-ODPF
version has output faders for production use.
S2-ODA Digital AUD Output Channel &
S2-ODAF Digital AUD Output Channel With Master Fader
This channel is common to every mixer and provides a digital and analogue output from
the AUD mix bus. The digital output is available as a balanced AES/EBU signal via standard
XLRs or as S/PDIF on phono sockets. The sample rate can be set automatically or by internal
jumpers from 32 kHz to 96 kHz and the output sample size from 16 to 24 bits. The balanced
analogue AUD outputs are available on a 15 way D type connector.
Button switches at the top of the channel select the monitoring source to the meterbridge.
The S2-ODAF version has output faders for production use.
S2-OMC Control Room Monitor Channel
The Control Room Monitor channel is used for the monitoring of various sources on the
control room loudspeakers and (presenters) headphones. A suitable power amplifier
connected to the channel monitor output must be used to drive the loudspeakers. A front
panel control is used to vary the monitor level. Headphones can be driven directly from the
channel headphone connector on the front or rear panel via the level control.
A 4 way electronically interlocking switch bank selects the source routed to the speakers
and headphones from either of two external inputs, the PGM, or AUD output. “Auto PFL”
buttons adjacent to each level control allow the monitoring of PFL when an input channel
has been selected to CUE/PFL. In addition, Split PFL can be selected to the headphones,
which will place the selected source in mono in one ear and PFL in mono in the other.
This channel controls the signal conditioning for the talkback input and output and routes
these signals to and from the talkback bus. Internal jumpers can be configured to allow
talkback to replace or dim the selected source. A Global Talkback system can be configured
to allow every contribution point in the control room and studio to communicate with each
other via their microphone and headphones.

Cleanfeed Terminations
If the console is supplied without Telco channels then J1 and J2 will be fitted to terminate
the cleanfeed mix busses. With one Telco channel only J2 is fitted and with two Telco
channels no jumpers are fitted. There is no default setting.
Synchronisation Mode and Sample Rate
The following jumpers, J3 to J9, are used for setting the Sync Mode and Sample Rate of the
digital output.
In Master mode, the digital output sample rate is simply set by, and locked to, the internal
on-board clock generator. No sync signal is used or required.
In Auto mode the sample rate follows the sync input. When the sync signal is not present
the sample rate will be set by, and locked to, the internal on-board clock generator at a
frequency determined by the jumpers.

detected the output will lock to the on-board clock generator at 32kHz.
In Slave mode, the sample rate follows the sync input. When the sync signal is not present
the digital output is muted.

Presets
Presets P1 & P2 are for altering the audio waveform symmetry (i.e. distortion) through the
VCA stage. They are factory set on final test and should not be adjusted further.
Preset P3 sets the VCA fader gain to 0dB when the fader is fully open. This is preset on final
test and should not require further adjustment, unless it has been found necessary to replace
the fader or other VCA components.
Presets, P5 (left) and P4 (right), set the peak digits through the conditioning circuits to the
analogue to digital converter. This is preset on final test and should not require further
adjustment.
Preset P8 sets the gain through the limiter that feeds the analogue to digital converters.
Preset P9 sets the threshold. Presets P6 & P7 are for altering the audio waveform symmetry
(i.e. distortion) through the limiting stage. They are all factory set on final test and should
not be adjusted further.
ADC Calibration
For optimum performance, the module should be calibrated when it has been powered up
for approximately 10-15 minutes. The circuitry and chipsets contained in the module will
warm up during this time and the performance will deteriorate unless calibrated (the noise
floor and dynamic range will be 1-2dB down on their best). The calibration cycle calibrates
the gain and the zero reference of the A/D converter.
To calibrate, hold down the PGM button and press the AUD button 5 times. The lock LED on
the front panel will flash quickly for 2 – 3 seconds and will return to it’s previous state. The
calibration procedure is now complete.

Jumper J12 selects the digital output mode between AES/EBU, pins 1 & 2, and S/PDIF, pins
2 & 3. The default is AES/EBU.
Preset P3 sets the VCA fader gain to 0dB when the fader is fully open. This is preset on
final test and should not require further adjustment, unless it has been found necessary to
replace the fader or other VCA components.
Presets, P5 (left) and P4 (right), set the peak digits through the conditioning circuits to the
analogue to digital converter. This is preset on final test and should not require further
adjustment.
Preset P8 sets the gain through the limiter that feeds the analogue to digital converters.
Preset P9 sets the threshold. Presets P6 & P7 are for altering the audio waveform symmetry
(i.e. distortion) through the limiting stage. They are all factory set on final test and should
not be adjusted further.
Gain can be altered using P4 and P5 on board versions S2-OP-04 and above, as P8 is no
longer fitted on these boards.
ADC Calibration
For optimum performance, the module should be calibrated when it has been powered up
for approximately 10-15 minutes. The circuitry and chipsets contained in the module will
warm up during this time and the performance will deteriorate unless calibrated (the noise
floor and dynamic range will be 1-2dB down on their best). The calibration cycle calibrates
the gain and the zero reference of the A/D converter.
To calibrate, hold down the PGM button and press the AUD button 5 times. The lock LED on
the front panel will flash quickly for 2 – 3 seconds and will return to it’s previous state. The
calibration procedure is now complete.

Three styles of dual meter panels, for displaying signal levels, are available for mounting in
the meterbridge: Dual VU panel S2-MVU, dual PPM panel S2-MPPM, and dual true PPM
panel S2-MPPT. The S2-ML53 is an LED meter for displaying both VU and PPM scales.
Illuminated LEDs on each meter panel indicate the monitoring source.
A meterbridge panel, S2-MPH can be linked to a dual meter panel and used to display
phase information on the selected source.
A meterbridge loudspeaker panel, S2-ML, can be used to monitor PFL and Reverse Talkback
via separate level controls. The speaker will mute in a “mic live” situation.
A comprehensive dual timer display, S2-MT, is available for timing events triggered from
mic or line input modules. The timer can also display the real time and date synchronised to
a standard time broadcast.
Two talkback panels are available. The S2-MTB6 can be used for communicating with up to
6 other mixers or dedicated talkback systems, and the S2-MTBS is used for interfacing with
a Sonifex Station Master.
A 3 button switch panel, S2-MSB3, is a meterbridge panel, 1 channel wide, with 3 buttons

modules. Six connectors on the board provide power and various signals to the meterbridge
modules and it is therefore possible, where space permits, to install 1 x S2-ML, 1 x S2-MT,
and up to three of your chosen style of meter panels. Meters can be configured to display
PFL, PGM, or Monitor, which is the signal selected by the buttons on the PGM output
module. The sixth connector provides power only for customer option meterbridge units.
When the S2 is used for a split frame installation, a meterbridge distribution board is fitted
to each meterbridge section.

G LO S S A R Y
Glossary
The reduction of a signal level. Attenuation is usually measured in dB.
AES
Audio Engineering Society.
AES/EBU
Professional digital audio standard covering frame format, connections
and interfaces. Interface is usually on XLR sockets and plugs.
Balance
The relative levels of the left and right channels
of a stereo signal.
Cleanfeed
A cleanfeed is the signal produced by the telco module, which is used
as the output to be fed back to a caller on a telephone line. A true
cleanfeed is the sum of all the other signals, which constitute the
programme output, except for the caller’s audio.
Clipping
The onset of severe distortion in the signal path, usually
caused by the peak signal voltage being limited by the circuit’s
headroom.
CMRR
Common Mode Rejection Ratio. This is the ratio of the extent to which
a differential amplifier will cancel noise, which is present on both
inputs, compared to its ability to amplify the wanted signal.
Cross-talk
This is the amount of an unwanted signal which appears,
or is induced, on a different or unassimilated signal. The problem is
usually most prevalent with adjacent channels.
CUE
See PFL.
dB (decibel)
A ratio of two voltages or signal levels, expressed by the equation
G LO S S A RY
Attenuation
dB=20LOG(V1/V2)
Adding the suffix “u” denotes that the signal is relative to 0.775V RMS.
Adding the suffix “v” denotes that the signal is relative to 1V RMS.
De-emphasis
Pre-emphasis and de-emphasis are techniques used to improve
the overall signal to noise ratio in communication channels.
The frequency response of the channel is weighted with a 6 dB per
octave slope prior to transmission (pre-emphasis), and then the
inverse of this weighting is applied at the receiving end (de-emphasis)
to restore a flat frequency response.
EIN
Equivalent Input Noise. It is the ratio of output noise to the gain. It
describes the level of noise which would need to be fed into an ideal
amplifier to produce the measured output noise.
EQ
EQualisation. This is the method of cutting or boosting selected bands
of frequencies in the signal.
S2 User Handbook
119
G LO S S ARY
G LO S S A R Y
120
Gain
The degree of amplification, or attenuation applied to a signal.
Hybrid
A device that allows a telephone line to be connected to a broadcast
desk in such a way that the caller may hear the programme output
without the caller’s voice being re-introduced onto the phone line.
Essentially a two to four wire converter.
LED
Light Emitting Diode.
Mix-minus
Another method of producing a cleanfeed, except that the caller’s
voice is removed from the signal electronically. Due to phasing
problems at the signal band edges, the mix-minus method often
produces a lower grade signal to the true cleanfeed method.
PAN
This controls the levels (usually of a mono signal) sent to the left and
right outputs and is an abbreviation of “panorama”.
PFL (CUE)
Pre Fade Listen, also called CUE. A function that allows the operator to
monitor the pre fader signal independently of the programme output.
Pre-emphasis
see De-emphasis.
S/PDIF
Sony/Phillips Digital Interface. Domestic digital audio interface
standard using phono connectors or optically using fibre-optic
connectors.
TBU
See hybrid.
T/B
Talkback (and reverse talkback, Rev T/B). This is the ability for two or
more studios to communicate with each other off-air.
Telco
TELephone COmmunication. The telco module is used by the
presenter to talk to telephone callers via a hybrid or TBU.
THD
Total Harmonic Distortion.
