Radio Broadcast Mixer Using S2-25 Chassis and Script Space.

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.

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).
