Monaural or Binaural Operation DIP Switches

The US2002 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 US2002 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 headphone operation is not supported.

For monaural operation with headphones or one speaker (factory default):

1.Set SW3-2 to off.

2.Set SW3-5 to on.

3.Set SW3-6 to off.

4.Set SW3-7 to on.

5.Set SW3-8 to on.

For binaural operation with 2 speakers:

1.Set SW3-2 to on.

2.Set SW3-5 to off.

3.Set SW3-6 to on.

4.Set SW3-7 to off.

5.Set SW3-8 to off.

Balanced/Unbalanced Switch (SW2)

This switch is set at the factory to the balanced (BAL) position for use with Audiocom intercom channels. Set the switch to the unbalanced (UNBAL) position for use with a Clear-Com intercom system.

Direct Program Listen Enable / Disable Jumpers

By default, each US2002 program input can be heard by all intercom stations that are listening on the corresponding intercom channel. This includes the US2002. Program input routing to the intercom channels can be turned on or off via the US2002 front panel programming. (See "Turning the Pro- gram Inputs On and Off", page 32.) Additionally, all program signals can be routed directly to the US2002 speaker or headset. This lets the US2002 operator hear the program inputs even if they are not being routed to the intercom channels. To disable direct program listening in the speaker or headset for one or more program inputs, reset the appropriate jumper as shown in Table 2.
