It contains muting circuit to minimize the effect of acoustic echo on the line. Provided with the unit are two back boxes for
either flush or surface mounting to a wall. A 12 Vdc power supply is included. The unit maybe be use for outdoor
applications.
OPERATIONS
The gain of the microphone and speaker are factory adjusted. If it is necessary to change the gain of either or both the
Audio Output of the microphone and speaker of the unit, it has to be done in small increments. For adjusting the gain of the
microphone, rotate clockwise to increase or counterclockwise to decrease, the potentiometer marked "MIC" slowly until
the desired level is attained. Somebody at the head-end has to listen to it while the adjustments are made. If the
microphone's gain is too high, it will attenuate the audio output of the speaker. The output of the speaker will then be
cutting off as you talk. If this happens, rotate the potentiometer marked "MIC" slowly counterclockwise to decrease the
gain of the microphone until the talkback sound at the speaker no longer cuts off.
To adjust the audio output of the speaker, rotate the "SPKR" potentiometer clockwise (increase) or counterclockwise
(decrease) slowly until the desired loudness is attained. If the audio from the microphone becomes attenuated, rotate the
"SPKR" potentiometer counterclockwise a small increment at a time until the microphone audio becomes louder again.
This unit has a built-in muting system that if the microphone's adjusment (MIC) is too high it is going to mute the speaker.
Also if the speaker's adjustment (SPKR) is too high, it's going to mute the microphone.
