Telex AUDIOCOM MS-2002 - Manual (Page 11)

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) microphone 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 turns 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 Mic Kill Send, do the following:
> 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:
> For channel 1 program interrupt during talk, set SW1-7 to on.
OR
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.
To enable the beep tone, do the following:
> Verify the call signal receive DIP switches are on (SW1-3 and SW1-5).
•
For incoming call beep in a headset, set SW3-1 to off.
• For incoming call beep in speaker 1, set SW3-1 to off and SW3-3 to on.
• For incoming call beep in speaker 2, set SW3-1 to off and SW3-4 to on.
NOTE: For more information on turning incoming call beeps on or off during operation, see “Incoming Call Beep ON /
OFF” on page 14.
