DESCRIPTION

AOPSP-PB

PLASTIC BACKBOX

(FLUSH MOUNT)

METAL BACKBOX

(SURFACE MOUNT)

OPERATIONS

Model AOPSP-PB is a wall mount two-way call stations containing a built-in line level electret condenser microphone, a

4” speaker and a 5/8 vandal resistant call button. It is designed to interface with various modes of audio/video

transmission systems such as:

IP Network Cameras

DVR’s

Video Servers

PC Soundcards

Provided with the unit are two back boxes for either flush or surface mounting to a wall. Also, a built-in call button

provides switch closure activation with the receiving device. a 12Vdc power supply is included with the the unit.

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 starts to get low, 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 is too high it is going to mute the speaker and vice versa.
