BusMatrix™ Input DIP Switch Settings

Each channel has a dedicated BusMatrix™ DIP switch bank that assigns that chan- nel's source input signal (see Figure 15). To assign the BusMatrix™ source input sig- nal for a particular channel, set only one of the seven switches to the right.

DIP Switch Settings

1L is for the assignment of the Left Bus Input #1

1R is for the assignment of Right Bus Input #1

1L+1R is for the assignment of a summed mono signal of the Left and Right Bus Input#1

2L is for the Left Bus Input #2

2R is for the Right Bus Input #2

2L+2R is for a summed mono signal of the Left and Right Bus Input #2

The seventh switch assigns the dedicated input to its respective channel

Again, only one of the seven DIP switches

STEP

DESCRIPTION

INSTALLATION

1.Move only one (1) DIP switch to the "ON" position for each channel.

CAUTION! EACH DIP SWITCH ALLOWS YOU TO MOVE ALL SEVEN SLIDE SWITCHES TO THE "ON" POSITION. IF YOU SET MORE THAN ONE SLIDE SWITCH TO "ON" YOU MAY CREATE AN UNDESIRABLE MIX OF INPUTS ON THE ENTIRE BUS.
