INSTALLATION

BusMatrixTM Input Switch Setting

Each channel has a dedicated BusMatrix DIP switch that assigns that channel’s source. To assign a signal from the Main Bus Input, select one of the first three switches which will give you either Left (L), Right (R) or Mono (L+R). To assign the channel’s dedicated input select the fourth switch. Only ONE switch should be selected to the “ON” position.

DESCRIPTION

CAUTION! The DIP switch physically allows you to move all four of the switches to the “On” position. If you accidentally set more than one switch "On", you will create an undesirable mix of inputs on the entire bus.
