 *

 * In the above, the 'loop1' relays are inactive, thus feeding IN1 to the

 * mixer (if 'add' is active) and feeding the mixer output to OUT1. The

 * 'loop2' relays are active, short-cutting the TSE-850 from channel 2.

 * IN1, IN2, OUT1 and OUT2 are TSE-850 connectors and DAC is the PCB name

 * of the (filtered) output from the PCM5142 codec.
