2.6 Input Routing
In the 280MA, any input can be assigned to Amp 1, Amp 2 or both. The two DIP switches labeled INPUT ROUTING are used (Figure 2.8). Follow the settings printed on the back panel next to the INPUT ROUTING switch. For example, to send input Channel 3 to Amp 1 and Amp 2, turn on DIP switches 13 and 14.

These switches (Figure 2.10) affect which signals are heard when another mixer is wired to the
IN: Any signal applied to the AMP INPUT connector will be mixed with the input signal(s).
OUT: Only the signal from the AMP INPUT connector will appear at the amplifier output.
