1. Introduction
The S0 v2 is a high quality yet simple to
operate radio broadcast mixer ideally suited
to community radio stations, for educational
purposes and for internet radio. It is easy
to use and provides the ideal solution for
those who do not require the advanced
functionality of a more complex unit.
Easy to understand, the S0 v2 includes a
telephone hybrid for making and recording
telephone calls and a 3.5mm stereo jack
for plugging in an mp3 player. The addition
of a USB port allows for recording to a PC
and for playing a PC automation system
directly through the mixer. The headphone
outputs have a built in limiter to offer hearing
protection and the studio speakers mute
when a microphone fader is open, with
automatic mic live sign switching.
Using many of the same components found
on the S2 and S1 mixers, the S0 v2 offers
quality and reliability in a cost effective
package. It also allows presenters and DJs
to be up and running quickly with a fully
featured radio studio mixer.

The Sonifex S0 v2 mixer is a compact, low cost, fixed format broadcast
mixing console designed for on-air radio use. It uses the same high quality
circuitry and components as the Sonifex S2 and S1 mixers to provide an
audio experience second to none. The S0 v2 can be fitted flush into a desktop or can be rack mounted directly using the front panel mounting holes.
The uncomplicated and intuitive front panel layout ensures that the unit
appeals to novices and broadcast professionals alike, whilst a range of user
configurable options allows for flexible operation.
The console consists of nine input channels:
•
4 x mono balanced XLR mic/stereo unbalanced RCA phono line inputs.
•
4 x dual stereo unbalanced RCA phono line inputs.
Introduction
•
1 x telephone balance unit (with line and handset ports)/stereo
unbalanced RCA phono auxiliary input with a parallel 3.5mm stereo jack
input on the front panel.
Providing in total 4 mic, 12 stereo line, 1 TBU & 1 stereo auxiliary inputs
which you can switch between.
Input Channels
Input source buttons at the top of each channel strip are used to select the
required mono or stereo source. The mixer has two main stereo buses,
PGM (Program) and REC (Record), so each channel also has PGM and REC
buttons to independently select which mixer bus the selected input is
routed to.
The XLR microphone inputs on channels 1 to 4 have individually selectable
+48V phantom power and a gain calibration potentiometer providing
up to 65dB of gain for the pre-amp. Input channel 1 also serves as the
microphone input for a dedicated talkback channel.
The stereo RCA phono line inputs on channels 1 to 8 have 10dB of gain at
the input to compensate for unbalanced consumer inputs.
Input channel 9 is a TBU and stereo auxiliary input channel. The TBU allows
direct connection to a telephone line and allows calls to be made and
received through the mixer using the handset connection. The auxiliary
channel can switch between 2 independent inputs, one on the rear panel
and one on the front panel.
Any channel which has the fader up is routed to the selected output, either
PGM or REC or both.
Gain for each channel is trimmed by the front panel TRIM control providing
±15dB of gain. A PAN/BAL(ance) control is available to facilitate stereo
imaging.
1
The use of VCAs controlled by the ALPS long throw 100mm faders gives
a smooth, repeatable response and ensures tight stereo tracking while
eliminating mechanical and electronic noise.
USB Audio for Playback & Recording
The S0 v2 has the option to send and receive audio over USB. This allows
the audio on the REC bus to be sent to a PC for recording or monitoring
purposes. Also, the S0 v2 can receive a USB audio stream from a PC and
route it to the auxiliary inputs on channel 8. Alternatively, this signal can be
routed to channels 5, 6 or 7 if required.
Output Channels
The S0 v2 has separate stereo PGM and REC bus outputs. The PGM bus is
output on balanced stereo XLRs and the REC bus is output on unbalanced
stereo RCA phono connectors. There are monitor outputs for presenter
headphones, guest headphones and loudspeakers.
Monitoring & Headphone Limiter
The monitor loudspeakers, presenter headphones and guest headphones
are on 6.35mm stereo jack sockets and the headphones can be plugged in
to the front and rear of the mixer. The monitor loudspeaker and headphone
levels are independently variable between 0 (cut off) and 10 (max).
With the concerns over listening levels being too high in headphones, the
addition of an adjustable limit level potentiometer on the rear panel of the
mixer is a great idea which limits the maximum level of the audio routed
to the presenter and guest headphone outputs. An illuminated MUTE LED
shows when a live microphone channel has muted the loudspeakers and
there is a MUTE contact output available to illuminate a ‘MIC LIVE’ light via
a 6.35mm stereo jack socket on the rear panel.
3
1
Introduction
A three way electronically interlocking illuminated switch bank selects the
source routed to the loudspeaker and headphone outputs from either PGM,
REC or from an additional unbalanced stereo RCA phono input EXT 1. This
external input can be used for monitoring an off air signal or studio output.
Green illuminated AUTO CUE/PFL (pre fade listen) buttons adjacent to each
level control allow the automatic monitoring of any channel that has been
selected to pre-fade, either to the monitors or headphones.
For the presenter headphones, SPLIT CUE/PFL can be selected which places
the selected source in mono in the left ear, and pre-fade in mono in the
right ear.
Metering
A pair of bright 21 segment LED meters can be configured to show either
VU or PPM metering. The meters follow the selection of the presenter
headphones including any pre-fade or split pre-fade function.
Talkback
A separate TALKBACK button is provided to allow the presenter to talk to
a guest on the guest headphones. The S0 v2 uses input channel 1 as the
talkback source.
Channel Remotes
The remote outputs for each channel are highly configurable providing a
comprehensive range of options to interface external equipment to the
mixer. Each channel input has its own START and STOP remote controls
which can be triggered when the channel is routed to the PGM or REC bus
and the fader is opened or closed. The remotes can be set-up to be either
pulsed or continuous latched outputs, and if in pulsed mode the START
button has the capability to produce repeated start pulses.
4
Configuration Settings
The S0 v2 has a range of software configurable options which can be used
to customize the operation of the mixer. It is possible to enable or disable
specific inputs, enable phantom power for the microphone channels and
limit which buses each channel can be routed to. Other settings control
auto cancelling of PRE FADE when the channel fader is opened and all the
remote output configurations.
The S0 v2 has an integral universal switch mode power supply, which uses
an IEC mains inlet.
Installation Notes
Atmosphere
The S0 v2 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. Other solvents may cause damage to paint or plastic parts.
Electromagnetic Radiation
Avoid using the S0 v2 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 S0 v2 mixer should be installed
and serviced by qualified personnel.

bus audio (selected by jumper) to be routed to a PC via USB interface for
the purpose of audio recording, with a return path useful for providing a
pre-fade listen (PFL) for a playout system.
The upgrade gives you a third option, allowing the cleanfeed output
from the telco channel to be routed to a PC via the USB. Setting both the
“microphone” and “speakers” within Skype to ‘S0 v2’ then allows full duplex
communication between the S0 v2 presenter and a caller, enabling the
user to audition the caller on PFL to set levels before either going to air or
recording a feature. See Appendix 2, S0 v2 Skype Modification.

Modifying the Configuration Options Using SCi
Software
Sonifex SCi software is a free of charge software package available to
configure the S0 v2 Mixer, as well as many other Sonifex products. The S0
v2 Mixer is supported in SCi version 2.0.5 and above. SCi is designed to run
on a computer running Microsoft Windows® XP or later.
Download the latest SCi Software
This is located on the Sonifex website in the Sonifex Downloads section:
http://www.sonifex.co.uk/technical/software/index.shtml

the S0 v2 Mixer should appear in the Device List window. If it is not listed,
check the cable between the S0 v2 and the computer and that the S0 v2 is
powered and repeat the scan. With the scan successfully completed, the
Device List can be closed and the Launcher should now show the devices
that were discovered. If the S0 v2 is in the list, but it has been reported as
“Not Supported”, this indicates that the specific driver file for the S0 v2 is
not installed. Visit the Sonifex website to download the S0 v2 driver, restart
SCi and repeat the device discovery scan.
Click on the S0 v2-Mixer entry to launch the S0 v2 SCi interface.
Download and then run the installer, and follow the on screen instructions
to install the software.
Connecting the USB Serial Port
The S0 v2 uses a USB Serial port instead
of a standard RS232 with a 9-way ‘D’ type
connector. Connect the S0 v2 to a spare
USB port on the computer using a standard
USB lead. The computer will automatically
install the required drivers when the S0 v2 is
connected for the first time.
Using SCi For The First Time
Once the S0 v2 Mixer is connected to the
computer, launch the SCi program. The first
thing to appear is the SCi Launcher which
shows a list of current devices, which initially
will be blank. Click on the large “plus” button
to start the device discovery scan. The SCi
Device List will be shown and the software
will search for any Sonifex products that
are connected to the computer’s serial and
network ports. Once the scan is complete,

Configuration Options
SCi for the S0 v2
The S0 v2 SCi interface offers an alternative method of setting the
configuration options. The available options are divided into 3 main
sections; Channel Configuration, Monitor Configuration and Info & Updates.
The bottom of the main screen shows the product and version information
of the connected unit.
The first tab shows the Channel Configuration options.
The settings are shown individually for each of the 9 input
channels and set the input and button modes and the
remotes operation. To change the settings on any channel,
first select the relevant channel and then select the required
settings for that channel.
This tab also has a general option to enable notification
messages to be sent via the USB Serial port when the state
of any of the channel or monitor controls change. This
allows user developed control software to respond to these
changes.
The second tab shows the Monitor Configuration options.
Fig 3-2: SCI Channel Configuration Screen.
22
Configuration Options

These settings control the operation of the AUTO CUE/
PFL button modes and the audio meter display type. This
section also controls the USB Audio input CUE/PFL mode.
This determines whether the USB Audio input channel is
automatically routed to the monitor section. If enabled,
the USB Audio input will be available on any of the
monitor channels that have the AUTO CUE/PFL function
enabled.
To store the configuration option settings onto the
connected S0 v2, press the Save Settings button. The S0 v2
will then restart with the new option values.
The current configuration option settings on the
connected S0 v2 can be reloaded into SCi at any point by
pressing the Reload Settings button. Any changes made
since the settings were last reloaded or saved will be lost.
Fig 3-3: SCI Monitor Configuration Screen.
The last tab, Info & Updates allows the current
configuration settings in SCI to be saved to a file on the
computer. This makes it easier to configure multiple
units with the same configuration settings. First select
the required settings in the Channel and Monitor
Configuration tabs, and then press the Save Configuration
button. A save dialog will be displayed allowing the
filename to be entered. Upon pressing the save button
the current settings will be stored in the selected file.
These settings can then be loaded whilst connected to a
different unit by pressing the Load Configuration button.
The settings stored in the file will be loaded into SCI and
automatically uploaded into the connected S0 v2.

Configuration Options
The Restore Defaults button returns the configuration
options on the connected S0 v2 to factory default settings.
The Firmware Update function allows the S0 v2 firmware
to be regularly updated with new features and bug fixes.
New firmware releases will be made available on the
Sonifex website. To update the firmware, press the Update
button and select the firmware file. The update only takes
a few minutes and the process can be monitored on the
progress bar on SCi and the meter display on the S0 v2,
which gradually changes from fully illuminated to off.
When the update is complete, the S0 v2 will automatically
reboot and SCi will reconnect and show the new firmware
version number.
The S0 v2 is designed to power up in the same state it
was in when power was removed. It is possible to clear
these saved settings so the mixer starts with all buttons
and routing switched off, except for those enabled by the
default configuration options:
1.
Ensure all faders are closed.
2.
Press and hold the Monitor EXT1, Monitor AUTO
CUE/PFL, Presenter AUTO CUE/PFL and Guest AUTO
CUE/PFL buttons.
3.
Press Reset Switch as shown in image below. A
single sweep on the LED meters indicates that the
saved states are being reset. The buttons can be
released.

USB Audio
4. USB Audio
USB Audio Output from the S0 v2
The USB Audio output from the S0 v2 is, by default, encoded from the audio
signal on the REC bus. It is possible to change this so that the USB Audio
output is encoded from the audio signal on the PGM bus. This involves
changing 2 jumper settings that are located on the PCB directly under the
front panel on the S0 v2. Contact Sonifex Technical Support for details on
how to change these settings.
The USB Audio port on
the S0 v2 allows live audio
transfer between the mixer
and a computer or other
compatible USB Audio device.
This effectively provides an
additional input channel
to the mixer that can be
routed to channels 5-8, and
a simultaneous output which
contains the audio from either
the PGM or REC output. The
stereo USB Audio port is
configured to run at a sample
rate of 44.1 kHz with 16 bit
samples in both directions.
No special software drivers
are required; simply connect a
standard USB cable between
the S0 v2 and the computer.
To check that a connection
has been made, open the
Device Manager in Microsoft
Windows®, and locate the
Sound, video and game
controllers section. A new
entry should appear “S0 v2
USB Audio”.
26
Once the USB Audio port is connected to a computer, it is possible to listen
to and record the audio. Microsoft Windows® identifies the USB Audio
input from the S0 v2 as an additional Line input recording device with the
device name S0 v2 USB Audio.
USB Audio Input to the S0 v2
Microsoft Windows® identifies the USB Audio output from the computer
as an additional Line output playback device with the device name S0 v2
USB Audio. The USB Audio input to the S0 v2 is decoded and routed to
channels 5-8. The USB Audio input on these channels is selected when the
INP1/INP2 button is illuminated amber. It might be necessary to change
the configuration options to enable this input to be selected. The USB
Audio input can also be used as a pre-fade input such that the audio is
automatically routed to any of the monitor and headphone outputs with
AUTO CUE/PFL selected once audio is present.

Connectors & Cabling
5. 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.

8. S0 v2 Skype
Modification
The latest upgrade to the S0 v2 mixer allows the
presenter to operate Skype on channel 9, with
the only interconnection being a USB cable. The
S0 v2’s USB audio feature has previously allowed
either PROGRAMME or RECORD bus audio
(selected by jumper) to be routed to a PC via
USB interface for the purpose of audio recording,
with a return path useful for providing a pre-fade
listen (PFL) for a playout system.
The upgrade gives you a third option, allowing
the cleanfeed output from the telco channel to
be routed to a PC via the USB. Setting both the
“microphone” and “speakers” within Skype to
‘S0 v2’ then allows full duplex communication
between the S0 v2 presenter and a caller,
enabling the user to audition the caller on PFL to
set levels before either going to air or recording
a feature.
Overview
The following modification procedure should be
completed if you intend to use Skype on channel
9 of your S0 v2.
Note: In doing so, the front panel auxiliary input
will no longer function.
Tools Required
• Pozi/Phillips screwdriver.
• Tweezers

channel 5. The secondary 3.5mm auxiliary
input will be available for selection on
channel 5 instead of channel 9.

5.
Remove the daisy-chained 3 way ribbon cable
that connects to channels 5-8 and reposition it
so that instead it spans channels 6-9.
6.
Replace the bottom panel and re-fit the ten
screws.

Hold down the following buttons whilst powering up the unit to enable
Skype mode:
The LED meter should perform a single sweep to indicate Skype mode
is being applied, and will perform a double sweep to confirm that Skype
mode is enabled.
10. The S0 v2 can now be connected via USB to a PC (using the audio USB
port). Open up Skype and go to Tools > Options. Select the ‘Audio
Settings’ tab/menu, and ensure the Microphone and Speakers are both
set to “Line (S0 v2 USB Audio)”.

To disable Skype mode:
1. Hold down the following buttons whilst powering up the unit to disable
skype mode:
11. Perform a test as follows:
• Connect a microphone to one of the microphone inputs and set the
fader for that channel fully up.
• Set input 9 to Aux Input 2 mode (press the top button until it turns
amber) and set the channel 9 fader fully up.
• Insert a set of headphones into the presenter jack socket and ensure
the volume is not turned fully down (but be careful not to set it too
loud).
• Complete a Skype test call, speaking into the microphone when
instructed to. If the S0 v2 is set up correctly, you will be able to hear
the instructions of the test call, and your own voice played back to you
at the end of the test call.
The LED meter should perform a single sweep to indicate skype mode is
being removed, and will perform a double sweep to confirm the mode
is disabled.
