S0v2 Radio Broadcast Mixer

A simple radio mixer for novice and professional users…

The S0v2 is a high quality yet simple to operate radio broadcast mixer ideally suited to community radio stations, for educational purposes and for internet radio. An upgrade to the original S0 mixer, it is easy to understand, the S0v2 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.
