Monaural or Binaural Operation DIP Switches

The MS-2002 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 front panel speaker. The combined signals also go to the Speaker 1 jack on the back panel. The MS-2002 can also be used with two (2) 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.

To set monaural operation with headphones or one speaker (factory default), do the following:

1.Set SW3-2to off.

2.Set SW3-5to on.

3.Set SW3-6to off.

4.Set SW3-7to on.

5.Set SW3-8to on.

Balanced Unbalance Switches

Both of the BAL-UNBAL switches on the back panel are set at the factory to the balanced (BAL) position for use with Audiocom intercom channels. Set the switches to the unbalanced (UNBAL) position for use with a Clear-Com intercom system.

Direct Program Listen Enable / Disable Jumpers

By default, each MS-2002 program input can be heard by all intercom stations listening on the corresponding intercom channel. This includes the MS-2002. Program input routing to the intercom channels can be turned on or off via the MS-2002 speaker or headset. This lets the MS-2002 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, do the following:

>Reset the appropriate jumper as shown in Table 2.
