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.

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-CMM Mic/Mic Channel and Rear.

The digital output is available as a balanced AES/EBU signal via a standard XLR or as S/PDIF on phono sockets. The balanced analogue AUD outputs are available on a 15 way D-type connector which also carries the two sets of latching relay contacts for the studio mutes. Button switches at the top of the channel select the monitoring source to the meterbridge. Meters in the meterbridge which are connected to the “Monitor Meter” position will display the selected signal from the electronically interlocking PGM, AUD, or CR MON buttons. The CR MON signal source is whatever is being monitored on the presenter’s headphone on the control room monitor channel, pre talkback and level control. This signal could be PGM, AUD, EXT 1, EXT 2, or PFL, as selected by the presenter. The digital output status bits (consumer or professional), output sample size (16, 20 or 24 bits) and sample rate (automatically or by internal jumpers from 32 kHz to 96 kHz) can be set. The digital output can be synchronised from an external input, or from an on-board master clock. There are 4 different sync modes : Master, Auto, Auto Lock and Slave. “ Following on from the Sovereign range of audio mixers, S2 combines all the features needed of a radio broadcast mixer in a stylish, flushmounting chassis : a wide range of input and output channels, PFL/cue, fader-start operation of equipment, automatic monitor muting on miclive, 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. “ S2-ODA Digital AUD Output Channel S2-PG S2 Penny & Giles Conductive Plastic Fader The input and output channels of an S2 mixer can optionally be fitted with high quality Penny & Giles faders. The illuminated LOCK LED shows that the digital output is locked to the onboard master clock, incoming word clock or AES/ EBU or S/PDIF compatible sync signal. The channel automatically searches for a sync signal on the Word Clock, or the selected digital input, and automatically locks to a valid sync clock. If sync is lost then the indicator will flash. Synchronisation can be jumper disabled.
