Radial SW4 4 Channel Balanced Stereo AB Input Switcher With Summed Outputs And PFL

The Radial SW4 is a four channel balanced audio switcher designed for wireless systems, mixing consoles and digital guitar processors to provide backup or greater operational flexibility in a live performance or concert setting.

Each of the four channels is equipped with two XLR inputs and a transformer isolated output that is capable of over +20dB signal handling at all frequencies. This makes the SW4 equally viable for wireless mic systems as it is for switching high output mixing consoles. Channels may be linked together for stereo, tri-channel or quad switching and additional SW4s may be linked for larger system requirements and remotely controlled if need be. Channel-1 is augmented with a 'mix' function that passively sums both inputs together for simultaneous use. All channels are routed to a master bus with 1 & 3 assigned left, and 2 & 4 assigned right.

For monitoring, each channel is equipped with a 3-position PFL switch that selects between source-A, source-B or the stereo bus via the built-in headphone amplifier. The bus may be switched to mono when used with wireless guitar systems. This is augmented with two isolated ¼" guitar outputs with a top-mounted 'set and forget' level control and a front-panel mono output to feed a monitor, tuner or guitar amp.

These features combined make the Radial SW4 the ideal choice for backup systems and for switching multiple balanced audio channels simultaneously.
