DESCRIPTION
AOP-SP-E 8/09
Model AOP-SP-E is a wall mount speakerphone designed to provide 2-way audio (listen/talkback) with various
modes of audio/video transmission systems such as:
IP Camera
DVRs
Video Servers
Provided with the unit are two back boxes for either flush or surface mounting to a wall. The AOP-SP-E can be used
as a stand alone unit or with companion AOP-XD. If used as a stand alone unit, the AOP-SP-E must be powered by
a 12Vdc, 500mA power supply. The unit maybe be use for outdoor applications.
The AOP-XD Audio Transceiver unit provides two-way audio with the receiving device (IP Camera, DVR, etc). It also
provides power to the AOP-SP-E. It receives the audio signal from the audio output of the receiving device and
amplifies it before it goes to the speaker portion of the AOP-SP-E. It also drives the audio signal into the audio input
of the receiving device. The AOP-XD contains adjustable level controls for audio signals coming from the AOP-SP-E
and receiving device. Two kinds of audio output/input jacks are provided by the AOP-XD (3.5mm mono and RCA)
which can be used to accommodate most DVRs, IP Cameras, etc. audio inputs.

INSTALLATION AND OPERATING INSTRUCTIONS
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.
