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.

INSTALLATION AND OPERATING INSTRUCTIONS

CONNECTING PoE SWITCH TO PoE IP CAMERA OR ENCODER (See Fig. 3 and 4)
1. Connect Ethernet cable from PSE (Power Source Equipment) to the Power+Data Input Jack of the IF-PX.
2. Connect Ethernet cable from camera to Power+Data Output Jack of the IF-PX. Camera should now have power
and data running through it. Power Indicator lights up.
4. AOP-SP Connection (two-way audio): Before connecting the AOP-SP series, make sure that the Ethernet
cables between the PSE, IF-PX and Camera are all connected.
a) Connect a 3 cond shielded cable between the AOP-SP and the pluggable header (Mic/Speaker Audio Terminal
Block) of the IF-PX. Connect terminal A of the AOP-SP to terminal A of IF-PX; connect terminal B of AOP-SP to
terminal B of IF-PX; terminal C of AOP-SP to terminal C of IF-PX and terminal SP of AOP-SP to terminal SP of IF-
PX.
b) Using the patch cable (stereo plug to stereo plug), connect the Audio Output Jack of the IF-PX to the audio input
of the camera or encoder. Connect the Audio Input Jack of IF-PX to audio output of the camera or encoder. See
interconnection diagram on page 5.
c) See installation instructions of AOP-SP for setting up and operation of the unit.
5. Setup camera for video and audio monitoring. Use an amplified speaker and a microphone to test the audio. A push
to talk microphone is recommended to minimize the echo when doing two-way audio. See camera user manual for
setting up the camera to the network.
