DESCRIPTION
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
Louroe companion unit AOP-XD Transceiver Interface maybe used but not required with the above
speakerphones. The unit can be used as a standalone equipment and can be directly connected to
an IP Camera, DVR or Video Server.
Refer to accompanying AOP-XD instructions for connections and operating instructions when used
with the AOP-SP-CF or AOP-SP-CS.
The AOP-SP-CF/CS provides line level audio input and output. It has amplifier that drives the built-
in 4" speaker. A 12 Vdc, 500mA power supply is required for this unit.
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.
