DESCRIPTION
OPERATIONS
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 RCA and
3.5mm 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.
Model AOPSP-PB
is for flush or surface
mounting to a wall or flat surface

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.

APPLYING POWER TO MODEL AOP-XD
Included with the AOP-XD is a 24V, 1A Power Supply. First connect small end to the 24Vdc jack located on the
back panel of AOP-XD. Then plug large 2-prong power block into a standard 120V electrical outlet or power
strip. Green LED on front panel will illuminate, indicating unit is powered. Model AOP-XD will send power to the
remote AOPSP-PB Call Station. For instructions regarding the functions of AOP-XD, refer to accompanying
AOP-XD instructions.
1) Connect RED wire to terminal marked “A”
2) Connect BLA CK wire to terminal marked “B”
3) Connect BARE wire to terminal marked “C “
4) Connect WHITE wire to terminal marked “SP “
