Headset Microphone Type Selection DIP Switch

SW1-1 applies only to a dynamic-mic headset connected to the dynamic-mic headset jack on the front panel. If the headset specifications indicate the microphone type is balanced, or if you are unsure, leave this switch in the off (default) position. If the specifications indicate an unbalanced microphone set SW1-1 to on.

☞For best results in noisy environments, a noise canceling (directional or cardioid) microphone is highly recommended. This is especially true if you are using the vox feature.

Mic Kill Send Enable DIP Switch

The US2002 can generate an inaudible signal which will turn off the microphones on all intercom stations on a channel (for stations that detect this signal). This feature is useful, for example, when an unattended microphone has been left on and is causing unnecessary noise on a channel. By default, Mic Kill is not enabled. To activate this feature set SW1-6 to the on position.

Program Interrupt DIP Switches

If you plan on using external program sources with the US2002, you have a choice of whether or not you want the program audio to shut off on the intercom channel while you are talking. By default, program audio does not interrupt during talk. You can change this as follows:

1.For channel 1 program interrupt during talk, set SW1-7 to on .

2.For channel 2 program interrupt during talk, set SW1-8 to on .

Incoming Call Beep DIP Switches

If call signal receive is enabled (switches SW1-3 and SW1-5), incoming calls will be indicated by red-flashing Call keys. An optional beep tone can also be used. Internal switches enable the beep tone. You can then turn the beep tone on or off via the front panel during normal operation. Enable the beep tone as follows:

1.Make sure the call signal receive DIP switches are on (SW1-3 and SW1-5).

2.For incoming call beep in a headset, set SW3-1 to off.

3.For incoming call beep in speaker 1, set SW3-1 to off and SW3-3 to on.

4.For incoming call beep in speaker 2, set SW3-1 to off and SW3-4 to on.

5.The procedure to turn incoming call beep on or off during operation can be found on page 33.
