DESCRIPTION
Model AOPSP-PB is a wall mount two-way call stations containing a built-in line level electret condenser microphone, a
4”(101mm) speaker and a 1”(25.4mm) 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. The AOPSP-PB can be used as a
stand alone unit or with companion AOP-XD. The AOP-XD Audio Transceiver Interface unit provides two-way audio
with the receiving device (IP Network Camera, etc.). Also, a built-in 1” (25.4mm) call button for provides switch closure
activation with the receiving device.
The AOP-XD provides power to the AOPSP-PB Speakerphone and drives the audio signals (line level) into the audio
input of the above receiving devices. It also receives the return audio signals from the “Audio Out” or “Speaker Out” of the
DVR, etc. and amplifies the output level for broadcasting through the speaker portion of the AOPSP-PB Speakerphone.
AOP-XD contains adjustable audio level controls for listen and talkback. Located on the back panel of the AOP-XD are
two RCA audio input and output jacks for accommodating most DVR’s, IP Network Camera’s audio inputs etc.
When the AOPSP-PB is used as a standalone unit, a 12Vdc power supply is needed.
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 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.
