Louroe Model AOP-SP-CF/CS is a ceiling mount speakerphone designed to provide 2-way audio
(listen/talkback) with various modes of audio/video transmission systems such as:
DVR’s
IP Network Cameras
PC Soundcards
Video Servers
The AOP-SP-CF/CS provides line level audio input and output. It has amplifier that drives the built-in
4” speaker. Also includes a 12 Vdc, 500mA power supply.
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.
