INTRODUCTION

The ASK-4 #370 is a two-way talk and listen single zone audio monitoring system. This system is designed to
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.
designed to connect to an DVR or PC soundcard.
Supports both Mode A and Mode B power options of IEEE802.3af

The gain of the microphone and speaker the AOP-SP-CF 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.

®

Model AOP-SP-CF is a ceiling mount self-amplified speaker/microphone

IP camera, encoder,

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

5

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 IF­PX.

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.
