S2 Radio Broadcast Mixer

S2 Radio Broadcast Mixer


S2 is a modular broadcast mixer which 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.
