Monaural or Binaural Operation DIP Switches
The US2000A can be used with a single speaker or monaural headphones (single- or
double-sided) for monaural operation. In this case, all audio signals are combined
and sent to the headphones and the Speaker 1 jack on the back panel. The US2000A
can also be used with two speakers for binaural operation. In this case, channel 1 is
sent to the Speaker 1 jack and channel 2 is sent to the Speaker 2 jack. Binaural head-
phone operation is not supported.

1. Set SW3-2 to off.
2. Set SW3-5 to on.
3. Set SW3-6 to off.
