S2 - Digital I/O Analogue Radio Broadcast Mixer
MIXING CONSOLES
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.
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 controlling remote
outputs, optional EQ on input modules, gram amp input
options and 2 main audio buses, allowing you to broadcast on
the PRG bus while recording on the AUD bus, with bus output
selection on each module.
Innovative Design
• The S2 chassis is available in 5 module
width sections, allowing 5, 10, 15, 20, 25
and 30 module width mixers. This means
S2 can be used for small newsrooms or
large on-air situations.
• Modular “pop-up” input and output
channels means that the mixer can
be maintained simply and quickly.
Hot-swappable 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 module can be in any position so
that customising the mixer for your own
purposes is easy.
• Large back-lit 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 unclipped
and reclipped 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
minimises the chance of failure, avoiding
lost air-time. Each module 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 XLR
•
•
•
•
Neutrik 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. There is also an optional
switcher to control 2 power supplies
providing redundancy.
High quality stainless steel is used for the
chassis and screws to prevent corrosion in
high humidity environments.
Each channel is metal coated internally to
provide exceptional EMC screening.

MIXING CONSOLES
MIXING CONSOLES - INPUT CHANNELS
S2 - Input Channels
There is a wide choice of input
channels for the S2 mixer.
Each channel has a number
of common features :
Assigning an Input Channel to an Output
Bus - Switches at the top of the channel are
used to select the output group routing, to
either Program, Audition, or both output
busses. Selecting the PGM and/or AUD
buttons routes the channel audio to the PGM and/or AUD mix busses. The
buttons illuminate green to indicate the
routing status.
Changing the Input Level - Coarse gain
is set using pre-set potentiometers on
the channel circuit board which allow
unbalanced inputs to be used on mono
and stereo line inputs. The front panel TRIM
control allows fine gain of ±12dB.
Changing the Signal Pan, or Balance - The
BAL/PAN control is used on mono channels
to pan the mono input signal in the stereo
image and on stereo channels to balance
the stereo image.
CUE/PFL (Pre Fade Listen) - 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 button lights
green when CUE/PFL is active and a jumper
option is available 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 on release, otherwise the button is
alternate action.
Fader Start & ON Button Control - The
ON button works in conjunction with the
100mm long-throw carbon fader and is used
to control channel remotes (e.g. starting a
CD player), routing and timers, etc. When
unlit, the channel is off. Flashing red indicates
that the channel has been selected to ON
but not routed to either PGM or AUD. 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. The
illumination in this case toggles between
unlit (channel OFF) and green (channel ON).
permanently disabled. Also, the ON button
can be configured to operate in a number of
modes, altering remote start functions, and
the channel ON function can be controlled
remotely by automation playout systems,
such as RCS® or VCS.
Scribble Pad - A scribble pad is provided at
the bottom of the channel for user labelling
of the channel function.
Programmable Button Settings
To make the S2 modules as flexible as
possible, every button on each channel can
be set to a number of different modes to
aid the use of the mixer and allow for extra
functionality. Each button can be set to either
operate manually, be permanently on, or u
S2-CMM Mic/Mic Channel
The mic/mic input channel is a dual mono
microphone input with a button switch to
select either Mic 1 or Mic 2.
Each Mic input has jumper settable phantom
power available at +48V and a high pass filter
to remove low frequency rumbles. When
enabled, the LF response of the microphone
is rolled off at 125kHz, 6dB per octave. If the
Mic input is used for the presenter’s mic it can
also become the talkback mic.
Equalisation is fitted as standard on this
channel and is enabled by the EQ button,
providing 10dB cut and boost at HF (6.5kHz)
and LF (100Hz).
The BAL/PAN control operates as follows : 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).
2
A balanced line level insert send and return is available for the Mic input. This is useful for hooking up an outboard
effects unit to be used with the microphone.
There are logic remote input controls for
Mic Cough muting and Reverse Talkback,
together with two separate output controls
for Mic Cue lights, which can be momentary
or latching.
The remote outputs on the 9 way D-type
plug are fed from NPN opto-isolators.
Both Mic inputs have a jumper selectable
output to facilitate either Control Room
speaker or Studio speaker muting and the
channel can also be used to control either
one of two separate timer displays.
Gold plated Neutrik XLR connectors are
used for the audio inputs and outputs.

S2 - Input Channels
S2-CML Mic/Line Channel
The mic/line input channel is a mono input
with a button switch to select either Mic or
Mono Line.
For the Mic input, phantom power at +48V
can be configured. The Mic input has a
jumper selectable high pass filter to remove
low frequency rumbles.
Gold plated Neutrik XLR connectors are
used for the audio inputs and outputs.
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.
“
The ON button works in
conjunction with the 100mm longthrow carbon fader and is used
to control channel remotes (e.g.
starting a CD player), routing and
timers, etc. When unlit, the channel
is off. Flashing red indicates that
the channel has been selected to
ON but not routed to either PGM or
AUD. 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. The illumination in this
case toggles between unlit (channel
OFF) and green (channel ON).
Equalisation is fitted as standard on this
channel and is enabled by the EQ button,
providing 10dB cut and boost at HF (6.5kHz)
and LF (100Hz).
A balanced line level insert send and return
is available for the Mic input for the insertion
of an effects, or voice, processor into the mic
channel. The send and return is disabled in
Line mode.
There are logic remote input controls for
Mic Cough muting and Reverse Talkback.
There are output controls for Mic Cue lights
and separate line remote start/stop controls
by fader or ON button. Both latching and
momentary contacts are catered for.
The remote outputs on the 9 way D-type
plug are fed from NPN opto-isolators.

The start function can be configured to be
either momentary (500mS) or latched for
each input. The remote outputs on the 9 way
D-type plug are fed from NPN opto-isolators.
Continuous momentary start can be enabled
such that when the fader is up and the
channel is on, each press of the ON button
triggers a momentary start.
Two remote pins can also be configured for
general use as either inputs, outputs, latching,
or momentary and active high or low. Uses for
this include channel live indication or specific
channel function remote control.
The BAL/PAN control adjusts the stereo
balance in the following manner : Full anticlockwise 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).
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.

MIXING CONSOLES - OUTPUT CHANNELS
MIXING CONSOLES
S2 - Output Channels
There are six different output
channels available, for
controlling monitoring in both
a Control Room and separate
Studio, with the two main
output channels also having a
master fader option.
The master output channels provide
balanced analogue audio outputs as well as
simultaneous AES/EBU or S/PDIF digital audio
outputs for both PRG and AUD busses. The
analogue mono output can be selected from
PRG or AUD and meter selection is available
to show either the PRG bus, AUD bus, or to
follow the Control Room Monitor selection.
Both Control Room and Studio Monitor
channels are available for controlling
what’s routed to the presenter’s and guest’s
headphones and monitor speakers. 2 external inputs can also be monitored.
A minimum of 3 channels need to be fitted
into a mixer : channels S2-OMC, S2-ODP (or
S2-ODPF) and S2-ODA (or S2-ODAF) must be
fitted and S2-OMS is optional.
S2-OMC Control Room
Monitor Channel
The control room monitor channel is common
to every mixer and is used for the monitoring
of various sources on the control room
loudspeakers (MONITOR) on a 6.35mm stereo
jack socket and presenter’s headphones
(PHONES) on 6.35mm stereo jack sockets.
Front panel control knobs are used to vary
the monitor and headphone levels and
headphones can be plugged in on the front
or the rear of this channel. The control room
monitor loudspeaker and headphone levels
are variable between 0 (cut off ) and 10 (max).
An illuminated Mute LED shows when a live
microphone channel in the control room has
muted the speakers, to prevent feedback.
Mute outputs on the remote connector of the
PGM output channel can be used to remotely
illuminate “Mic Live” lights.
