DESCRIPTION

Model AOP-SP-W 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-W can be used as a
stand alone unit or with companion AOP-XD. If used as a stand alone unit, the AOP-SP-W must be powered by a 12Vdc,
500mA power supply.

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-W. 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-W. 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-W and
receiving device. Two RCA type of audio output/input jacks are provided by the AOP-XD which can be used to
accommodate most DVRs, IP Cameras, etc. audio inputs.

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.

Color Code of recommended wiring is:

RED - 12Vdc power to microphone
BLACK - Audio Output
BARE - Ground (microphone and speaker)
WHITE - Speaker

Color Code may vary among wire manufacturers

WIRING CONNECTION TO AOP-SP-W

Located on the bottom right side of PC board is a 4-pin terminal
block marked A, B, C, SP

A = +12Vdc power (red wire)
B = Audio output of microphone
C = Ground (microphone and speaker
SP = Speaker input

Bring one end of recommended cable and connect as follows:

WIRING REQUIREMENTS

3 Conductor consisting of:

+

2 Conductor shielded, 20 gauge
with 22 gauge drain

+

1 Conductor unshielded, 20 gauge

All in the same jacket

West Penn 358 or
equivalent

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“

Drill an opening top, bottom or back side
of backbox for passing wiring or for
connecting conduit.

WIRING CONNECTION FROM AOP-SP-W TO COMPANION AOP-XD
AUDIO INTERFACE UNIT

The rear panel of AOP-XD has a 4 pin terminal block marked A, B, C, SP

Bring in other end and connect as follows:

1) Red wire to terminal A

2) Black wire to terminal B

3) Bare wire to terminal C

4) White wire to terminal SP

This completes the wiring between the AOP-SP-W and AOP-XD. For operation instructions and functions
regarding Model AOP-XD Transceiver Interface unit, refer to the AOP-XD instructions that accompany the unit.
