Louroe Electronics AOP-SP-E User manual

DESCRIPTION
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
It contains muting circuit to minimize the effect of acoustic echo on the line. Provided with the unit are two back boxes for
either flush or surface mounting to a wall. A 12 Vdc power supply is included. The unit maybe be use for outdoor
applications.
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.

Bring one end of recommended cable and connect as follows:
Located on the bottom right side of PC board is a 4-pin terminal
1) Connect RED wire to terminal marked “B”
2) Connect BLACK wire to terminal marked “C” (together with bare wire)
3) Connect BARE wire to terminal marked “C“
4) Connect WHITE wire to terminal marked “SP“
5) No connection on terminal “A”
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
WIRING CONNECTION TO IP CAMERA OR DVR
POWER CONNECTION
Bring the other end of the cable to connector that matches the audio input
and outputs of the receiving devices
1) RED (positive audio) and BARE (ground) are soldered to the audio
connector (RCA, 3.5mm Mono or Stereo plugs). This connector goes
to the Audio input of the receiving device (IP Camera, DVR, etc)
2) WHITE (positive audio) and BLACK (ground) are soldered to the another
audio connector (RCA, 3.5mm Mono or Stereo plugs. This connector
goes to the Audio output of the receiving device (IP Camera, DVR,
etc).
The unit has a 2-pin terminal block for power connections marked 12Vdc
1) Connect the positive 12Vdc of the power supply (AD-1) to the terminal
marked +
2) Connect the negative or ground of the power supply to terminal marked
GRD
