Introduction

1 Introduction
The Sonifex S1 Mixer is a compact, low cost,
fixed format radio on-air mixing console
designed to cater for a wide and far reaching
broadcast market. On the surface, it is simple
and easy to use but it also has hidden layer
of variety and flexibility for those who like to
get into the heart of their products, tweak
the engine so to speak. Using the latest
technology components, S1 offers digital
audio quality with analogue reliability. S1 has
both digital and analogue input channels,
together with simultaneous analogue and
digital outputs.
Innovative Design
• The S1 can be rackmounted or used as a
desktop mixer
• The back panel connections can be rotated
onto the back of the unit or onto the base
of the unit
• Large back-lit buttons allow you to see the
status of the mixer at all times.
Superb Audio Quality &
Unquestionable Reliability
• The S1 uses the latest semiconductor
technology to allow input of SPDIF
& Toslink digital audio signals up to
24bit,192kHz, and the output of AES/EBU
and S/PDIF digital audio signals up to 24
bit, 96kHz sample rate.

Introduction
• 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 the S1 minimises the chance of
failure, avoiding lost air-time.
• ALPS long-throw 100mm faders give a smooth, repeatable response and
the XLR Neutrik connectors used are an industry standard.
• The use of VCA’s controlled by the faders ensures tight stereo tracking
and eliminates mechanical and electronic noise.
• The S1 has an internal power supply providing regulated, ripple-free
power, to the mixer.
• High quality anodised aluminium is used for the chassis to…
Progress
Following on from the Sonifex Sovereign range of audio mixers, the S1
combines all the features needed of a radio broadcast mixer in a stylish,
flush-mounting chassis: a wide range of input and output channels, CUE/
PFL, fader-start operation of equipment, automatic monitor muting on
mic-live, light switching remote outputs, EQ on input modules, two auxiliary
busses,two external inputs and a main program audio bus.
Flexible
The S1 is a highly configurable unit and has been designed to be jumper
free, allowing the user to alter the configuration quickly whilst still on air
rather than having to take apart the unit armed with a pair of tweezers and
a magnifying glass. The majority of the desk can be setup and controlled
using the Sonifex SCI Software. This opens up a world of options:
• Producer Controlled Environment – SCi allows the producer or engineer
to control all settings and parameters reducing the required skill set of
the Presenter and leaving them to focus on their broadcast.
• Remote Control – Control external equipment using the dedicated
remote control ports. These are great for starting or stopping CD players
and other external equipment and are fully configurable to suit most
manufacturers and remove limitations.
2
• Global Talkback – Allow all your guests to hear each other through their
headphones, alleviating the risk of Mic/ Headphone feedback. (for more
details refer to page 19.
• Automation Tally – Give a visual indication of an impending event to a
presenter using the versatile GPIO system.
• Many more examples covered in the user setup section.
Installation Notes
Atmosphere
The S1 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.
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 S1 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. In all cases the S1 mixer should be installed
and serviced by qualified personnel.
Dimensions and Cut-Out Sizes
The cut-out size is for reference only and should be checked with your
mixer.

The Stereo Cleanfeed channel has one
balanced stereo input and a balanced
stereo cleanfeed input, on XLR connectors.
The channel is intended for use where a
remote stereo source, such as another
studio connected via ISDN, requires a
stereo cleanfeed return. The cleanfeed is
generated by a separate stereo cleanfeed
bus which follows the PGM output routing
matrix.
External Inputs
Two external inputs are available to the S1
through a 9 pin D-Type connector located on the
rear panel. The external inputs are used for audio
which should be heard in the control room but
not on air. The pin out for this connector can be
found in Appendix B.

Channel 7 and 8 – Stereo Line / RCA
Inputs
Channels 7 & 8 have one balanced stereo
input and an unbalanced RCA stereo input.
Channel 7 also has DROP IN connector
which allows for an input from a a 3.5mm
jack connector.
Fig 2-8: Channel 6 – Stereo Line /

Channel 9 and 10 - Stereo Line /
Digital Inputs
The Digital Stereo Input channel has
one standard stereo XLR Analogue Input
channel & one 24-bit 192kHz digital inputs
with a button switch to select between
them. The digital input is auto sensing
& can be connected via either SPDIF or
Toslink. The digital signals are converted
to analogue and from this point the
channel functions are the same as the Dual
Stereo Line Input channel.

Input Selection
Selecting the button changes the channel input
connection between Input 1 (Mic) and Input 2
(Line). The button is illuminated in red to indicate
when input 2 is selected. When the channel is
routed, so that the ON button glows green, the
input selection cannot be changed.
Fig 2-12: Input
Selection
Channels 3 and 4 have three selectable inputs;
Mic, XLR Mono Line, ¼” unbalanced stereo line.
The input selection button will glow red when
Mono Line is selected and Orange to indicate
the stereo input is selected. The button can
be configured using SCi so that the button is
forced to a particular input or alternatively the
selection of either the Line input or the Stereo
Line input can be inhibited so that the button has
only two options as two line sources cannot be
simultaneously connected.
DROP-IN Jack
On Channel 7 only, there is a 3.5mm insert jack
allowing the direct connection of mp3 players

or other portable consumer equipment. When
the INSERT jack is in use, it overrides the Input
Selection Button.
the position of the faders. This is where to use
the trim pots, for level adjustment which remains
constant through the mix.
AUX Controls
Each channel is sent to both auxiliary buses at
all times. The AUX controls allow adjustment
of the level of each channel on the bus to
achieve a perfect mix. The control changes the
level between fully attenuated and unity so to
remove a mix from a particular auxiliary bus, fully
attenuate that particular channel.
PAN Control
The Pan control is used to pan the mono input
signal on channels 1,2 and 5 in the stereo image.
Fully 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).
Equalisation Controls
In some situations you made need to change
the equalisation of your audio. 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
fundamental frequency of human voice generally
sits between 100 and 150 Hz. Try lowering the LF
control on microphone channels to get rid of any
unnecessary low frequency audio while slightly
boosting the HF to add clarity.
TRIM Control
The Trim control is used to tweak the level of
the channel on the PGM output. It provides
an additional ±12dB of gain to fine tune the
input signal level. It is a good idea to set up all
your audio channels so that they are all at the
same reference level when the fader is fully up,
meaning the mix levels are determined solely by
Fig 2-14: AUX
Controls
Fig 2-15:
Equalisation Controls
Fig 2-16: TRIM
Control
Balance Control
The balance control is used to alter the stereo
image of a stereo input source on channels 3, 4,
6, 7, 8, 9 and 10. Turning the potentiometer fully
anti-clockwise shifts the signal to the left and
increases the signal by 6dB (right channel reduces
by 6dB); fully 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 prefader 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
PAN control. The button is illuminated in green when
CUE/PFL is active. There is a configuration option
to cancel the CUE/PFL selection when the fader is
raised. This button works with both a momentary

is cancelled when released, otherwise the button is
alternate action.
CUE/PFL & T/B Selection
On channels 5 and 6 the CUE/PFL and T/B button
operates similarly
to a standard CUE/PFL button except the talkback
source is also routed to the respective cleanfeed
output when the channel input is set to Input 2 (5.
Telco or 6. Stereo Cleanfeed).
Unlit
When unlit the channel is off.
On solid - red
Steady red indicates that the channel is ON and
“armed”, ready for the fader to be raised.
Fig 2-20: CUE/PFL &
T/B Selection
An additional option that is configurable using SCi
allows the presenter to CUE/PFL the Telco or STCF
inputs whilst preventing the talkback source from
being routed to the cleanfeed outputs.
If Talkback routing on this channel is ‘disabled’,
the CUE/PFL & T/B button shall flash green when
selected to indicate that talkback is not routed to the
cleanfeed bus. Talkback can be routed to the stereo
cleanfeed bus by holding the CUE/PFL & T/B button
and the button will glow solid. When the button is
released, talkback will return to the unrouted state &
the button will return to flashing green. CUE/PFL can
be deactivated by a momentary press of the button.
This option only applies to Input B of this channel.

Fig 2-21B: LINE
HOLD
Flashing red
On channels 9 and 10 when Input 2 (Digital Input)
is selected, the channel ON button will flash red to
indicate that the input is not locked to a valid source.
The channel cannot be opened if the Digital input is
not synchronised to a valid source.
The button can also flash green and flash orange.
Please refer to the tally back portion of section 4
(page 23) for more information.
ON Selection
The ON (called LINE HOLD on channel 5) button
works in conjunction with the fader. It is used to
control channel remote output logic, channel routing,
and timers. The button LEDs show the various
operational states of the channel.
On solid - green
Raising the fader changes the illumination to green
indicating that the channel is live. With the button
unlit the fader may be raised and the channel can be
operated simply by selecting ON. The illumination
in this case toggles between unlit and green. The
channel remotes and timers are triggered when the
fader is up and the channel ON button shows green.

Fader
The 100mm VCA fader provides a method of dynamic
in-show level control and operates between fully
attenuated in its lowest position and unity gain when
fully open. The channel input signal is routed to the
PGM output whenever the fader is open, and the ON
button is selected. If using the auxiliary bus post fade,
the fader position also affects the level of the channel
on the auxiliary buses. The faders can be forced up for
remote control applications using one of the General

Monitor and headphone sockets
The S1 provides a monitoring system
to monitor all output channels or
the external inputs. The is useful for
setting up the mixer outputs or to
simply listen to the mix in a control
room. There are four jack outputs in
total; two paralleled presenter outputs,
one guest output and one monitor
output. The source which is heard on
the monitoring system is selectable
via push button. The buttons are set
to interlocking mode by default, which
means the button pressed becomes
the source, cancelling all others. An
alternative mode of operation is mixing
mode, which mixes the output sources
onto the monitor bus instead. All the
buttons can be locked out in either the
off or on positions to stop accidental
selection. To find out how to set up
these functions further please view

PGM Output
The PGM output provides stereo balanced XLR
outputs. The PGM Output is used as the main
transmission bus. All channels that are on and
faded in are mixed on to this bus.
Cleanfeed Outputs
The Telco cleanfeed is a mono balanced output
used to return a mono version of the program

connector. These both carry
the PGM output. The digital output can be synced to either the on-board
master clock or either of the designated sync inputs. There are three
distinct synchronisation modes:
Master Mode
The digital outputs are locked to the on-board master clock and is therefore
constantly operating at the chosen sample rate. No sync signal is used or
required. The internal clock can be set to 32, 44.1, 48, 88.2 and 96kHz.
Lock Indicator
The illuminated lock indicator shows that the digital
output is locked . If synchronisation is lost then the
indicator will flash.
Auxiliary Outputs
The S1 has two auxiliary buses so that alternative outputs
from the PGM can be created and used. The mix that is
created on these buses is available from a 9 pin d-type
connector which is located on the rear panel. For more
information on the use of the auxiliary bus, please read

The auxiliary buses provide two alternative outputs to use as desired. This
opens up several practical options to the user.
Auxiliary bus to record a session
The user can connect the either auxiliary output to recording equipment
and record what is present on the bus. The producer decides what audio
is on the bus by setting the volume on each channel to the appropriate
level, creating a totally new mix. Using PRE and POST allows the producer
to discriminate between recording all audio or just what is faded in at the
time. The producer can also decide what output level the mix should have
by using the master volume control for the particular AUX channel in use.
Auxiliary bus to record an off air phone call
It is possible to use an auxiliary bus to record a telephone conversation
off air, whilst transmitting from the PGM output. Before the conversation,
chose an auxiliary bus and turn down all of the individual channel gains.
Turn the gain on the presenters channel (typically channel 1) and the telco
channel (typically channel 5) to the required levels and set the bus to PRE.
When the phone call is received, the presenter can press the CUE/PFL &
T/B button and talk to the caller. The conversation can be recorded using
19
3
Mixer Applications
external equipment connected to the specific auxiliary output on the back
panel.
Log the presenter
The user can create content review material by logging all presenter
dialogue. Chose an auxiliary channel and turn down all individual channel
gains for that channel. Turn the presenters auxiliary channel gain to the
required level, set the master gain and use in POST mode. All on air material
from the the presenters mic can be recorded from the auxiliary output on
the back panel.
To avoid the patches of silence that would occur while audio or jingles
are playing, use the remote control start and stop signals that are used to
trigger the CD player, jingle player etc to also trigger the logging equipment
if this option is available. Find out more about the remote control ports in
chapter 4.
Create a talkback source
If you require multiple talkback sources, create a custom talkback mix on
an aux channel and set is to PRE. Connect the Aux Output L to the channel
1 LINE input. After connecting the presenters Mic to channel 1, Use SCi (to
find out more about SCi, turn to section 4) to configure the talkback source
to channel 1 Line and lock the channel 1 source button to Mic Input. This
will prevent a loop back connection.
Use an auxiliary bus to create a clean feed for a hybrid unit
If the user would like to use a second hybrid, an auxiliary channel can be
used to create a clean feed return. Turn the gain to all channels that are
being broadcast to the required levels except for the channel which is
receiving the audio from the second hybrid. Select POST so that everything
that is heard has been mixed correctly. This channel should be muted.
Connect the left channel of the auxiliary output to the the second hybrids
clean feed input. If presenter would like to talk to the caller off air, turn off
the presenter channel and fade in. This will allow the the presenter to be
20
heard on the auxiliary bus but not on the PGM output. The presenter can
press CUE PFL on the second hybrid channel to listen to
the caller.
User Guide – Section 3-4 External equipment and
the S1
Most of the equipment needed such as microphones, headphones
and CD players are self-explanatory. Occasionally you may need extra
external equipment to really make the most of the mixer. Here are a few
suggestions:
Headphone distribution amplifiers
If the application requires more than one set of guest headphones, then a
headphone distribution amplifier is required. This will take one headphone
output and create multiple new outputs from it, without affecting the signal
or line impedance. Simply take the output from the guest headphones
socket and connect it to the distribution amplifier. It is recommended that
you use the SONIFEX RB-HD series.
Microphone amplifiers
Some applications may require more microphone inputs. If this is the case
you could use the Line inputs with dedicated microphone amplifier. Connect
your microphone to the amplifier’s input and connect the amplifier’s
output to the required line input. It is recommended that you use the
SONIFEX RB-MA series.
Telephone hybrid
Use a telephone hybrid to open the show up to interaction with the outside
world. A hybrid allows you to receive phone calls and send them to your
mixer as audio. Connect the hybrids audio output to the mixers telco
channel (channel 5) and connect the channel’s clean feed output to the line
input on the hybrid. The mixer has been designed to work with the Sonifex
HY-03.

live and on-air. A set of latching relay contacts, activated by a control room
mute, are available on the Talkback 9 way D type socket on the rear panel
of the mixer for the Control Room On-Air light. See the pin-outs of the
talkback interface for details. Shown below is an example of connecting the
latching relay contacts on the talkback interface to a SONIFEX RB-LC3. The
remote connection on the RB-LC3 is active low.
Mic Cue Light
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).
3
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
RB-LC3 Light/Power controller is a suitable unit that will control up to three
On-Air lights and/or Mic cue lights.
Voice Processors On Mic Channels
To use an outboard effects unit with a microphone, for example, a voice
processor an auxiliary bus could be used and returned through a spare
input channel.
Use of the external inputs
The external inputs found on the rear panel are used to send audio to the
presenter and guest headphones and to the monitor output. The external
inputs can not be routed to the PGM output. Theses should be used to relay
information information or audio to the presenter and guests which should
be kept isolated from the transmission path.
Connect portable audio sources using DROP-IN
The drop in socket is used to add audio from an additonal external source
such as a portable MP3 player. Connect the source to the mixer and the
source will over ride all audio on Channel 7. This can be routed to the PGM
output.
Meterbridge
The meterbridge is an expansion port that allows external meterbridge
components to be connected. This includes a variety of different meter,
timer and monitor panels. The meterbridge port can also supply up to
15V @ 200mA to external equipment if required. Appendix A (page 31)
contains the pin out and pin description for this port. For more information
on meterbridge components, please contact Sonifex.
Open collector outputs for each channel are provided on the Remote

example, when the presenter prefades that particular channel.
The remote control ports are available so that the user can control external
equipment from the mixer. The two remote connectors on the rear panel
contain all of the START & STOP outputs from the input channels. Each
channel input has its own START and STOP remote controls except the
microphone inputs which only have START outputs. In the eventuality that
you require a microphone stop control signal, this could be configured using
one of the general purpose outputs.
Remote Mode
The remotes can be configured in a variety of different ways:
• Remotes Disabled
- The remotes are not used and are not controlled by the desk
- If the stop control is set to continuous, then the stop signal will always
be on
22
- n this mode the stop signal is generated when the ON button is turned
off (not glowing)
• Telco Mode with CUE/PFL
- This operates the same as the telco mode except the CUE/PFL button
can also generate start and stop remote signals
Momentary/Continuous
• Each remote output can be configured to operate in momentary or
continuous modes.
Repeated Starts Mode
It is possible to configure the ON button to operate in a Repeated Start
Mode. If this option is enabled, a start pulse will be sent when the channel
initially goes live. If whilst the channel is live (ON button is green), the ON
button is pressed again, an additional start pulse will be sent.
Advanced Configurations
User Guide – Section 4-2 General purpose inputs
and outputs
The S1 has five General Purpose Inputs/Outputs (GPIO) available. Each
GPIO has been designed to be very versatile & almost any operation with
the mixer can be achieved when utilising them.
General Purpose Inputs
Each GPI can be configured to perform up to 10 different operations from a
single input. For example, in a remote play out situation, you may want to:
• Force 4 channels ON with the faders forced up
• Force 4 channels to input 1
• Mute the Control Room Monitors
This configuration would utilise 9 of the 10 operations available for an
individual GPI.
Options / Configuration
The Input can be configured to operate in several different ways:
• Momentary / Continuous GPI
• Active High / Low GPI
To Configure a GPIO please refer to the GPI: mode in the Serial Command
Interface Section.
General Purpose Outputs
Each GPO can be configured to generate an output from up to 10 different
internal controls. For example, a GPO could be configured to generate a
global talkback function. The GPO would be setup so that:
• When microphones 2, 3 and 4 are all not live, generate a GPO continuous
output
The GPO could then be linked back into one of the GPI’s with the Input
Configured to:
4
• Force PFL on Mics 2,3 & 4
• Enable Auto CUE/PFL Guest
This would allow the guests to freely talk to each other until one of their
mics goes live.
Options / Configuration
The Output can be configured to operate in several different ways aswell:
• Momentary / Continuous GPO
• Active High / Low GPO
Tally Back
In addition to the telco remote mode, the channel can be configured to
show the state of the external equipment. Once the channel has been
armed, the channel will flash green, until a GPI signal (tally back) has been
received back to confirm that the external equipment is now online. This
will then allow the channel to be opened. If the external tally is lost (ie a
tbu goes offline), the mixer will wait for 1 second before muting the channel
& returning to the green flashing state.
In telco mode, it is possible to use the telco mode to set up an external link
and then switch over to use the other input on that particular channel. If
the tally is lost whilst still monitoring the other side of the input channel,
the on button shall flash orange at a 25% duty cycle, to show that the
external link has been lost.
To re-setup the link, the user must switch to the channel with the telco
mode, turn the channel off, & then turn it back on. When the tally is
received from the external equipment, the orange/green flashing will stop.
Automation Tally
An automation tally can be used as a visual indication to the presenter
that something is happening or about to happen. When an auto tally is
configured on a playout system channel for example, the auto tally could
be used to indicate to the presenter that the playout track is about to end.

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.
The main types of connectors used with the S1 mixers are the following:

Serial Communication Protocol
Sonifex SCi remote control software handles all communication with the S1
via a convenient graphical user interface. However, this protocol is provided
for those users who wish to develop their own remote control applications
or communicate with the S1 using a text-based terminal program. For more
information on how to install and operate the SCi software, please see page
24. Details of the protocol are available upon request. Please note that
protocol for the GPI and SRQ commands are not included.

Attenuation
The reduction of a signal level. Attenuation is usually
measured in dB.
EQ
EQualisation. This is the method of cutting or
boosting selected bands of frequencies in the signal.
AES
Audio Engineering Society.
Gain
AES/EBU
Professional digital audio standard covering frame
format, connections and interfaces. Interface is
usually on XLR sockets and plugs.
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.
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.
S/PDIF
Sony/Phillips Digital Interface. Domestic digital
audio interface standard using phono connectors or
optically using fibre-optic connectors.
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 channel is
used by the presenter to talk to telephone callers via
a hybrid or TBU.
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.
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)
46
A ratio of two voltages or signal levels, expressed by
the equation:
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
