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.
Note: For best results in noisy environments, a noise canceling (directional or cardioid) micro
phone is highly recommended. This is especially true if you are using the Vox feature.
Mic Kill Send Enable DIP Switch
The MS-2002 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 MS-2002, 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 .
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 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.
