R&B – Router & Bass Management

The Ultimate Routing Management for your Speaker Setup
R&B is an 8 by 8 matrix that allows you 3 different configurations. Whether you are using your PSI Audio setup in stereo or surround, R&B can save you a lot of time, by allowing easy switching between three different monitoring systems. It allows use of a single multichannel speaker system for monitoring multichannel, satellite+sub, or stereo program material. R&B allows subs to be used as bass extensions or LFE. Standby/Mute and switching modes can be controlled by an standard double footswitch.
