INTRODUCTION
The ASK-4® #370 is a two-way talk and listen single zone audio monitoring system. This system is designed to
tap POE power and provide two-way communication through the IP camera’s video management software.
The IF-PX is a POE inline interface that taps some power from the IP camera’s Ethernet powered cable to
supply power to the AOP-SP-CF Speaker/Microphones.
IP camera, encoder,
Supports both Mode A and Mode B power options of IEEE802.3af
Model AOP-SP-CF is a ceiling mount self-amplified
speaker/microphone designed to connect to an DVR or PC soundcard.

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.
