AUDIO MONITORING SYSTEM
INSTALLATION AND OPERATING INSTRUCTIONS
The ASK-4 104 is a four zone audio monitoring system designed to interface with a DVR, VCR or other recording device
®
that accept line level audio. The AP-4 Audio Base Station has 4 microphone inputs, contains a built-in 3’ speaker and
volume control for producing live audio and playback. It has loop out RCA output per microphone so each microphone
can be recorded individually. It also has a selectable audio output that produces audio to a recorder for that zone or
microphone selected. The Verifact™ A microphones are omnidirectional pre-amplified microphone that produces line level
audio output.

INSTALLATION AND OPERATING INSTRUCTIONS
MICROPHONE CONNECTIONS TO AP-4
All Louroe Verifact Microphones contain a 3-pin terminal block marked A, B, C. All Louroe base stations contain similar
3-pin terminal blocks marked A, B, C. Refer to interconnection diagram p 5.
1) Take one end of recommended cable to first microphone location and connect:
2) Run other end of cable to the AP-4 Base Station location and connect to the 3-pin terminal block of the audio
3) Repeat the same procedure for the remaining microphones using the additional terminal blocks marked zone
CONNECTING AP-4 TO A RECORDING DEVICE (DVR, ETC.)
A) If connecting to a VCR or to a DVR with one audio input:
®
A = 12Vdc Power (red wire)
B = Audio Output (black wire)
C = Common Ground (bare wire)
Red wire to terminal A (12Vdc)
Black wire to terminal B (Audio Output)
Bare wire to terminal C (Ground)
zone in which the remote microphone is assigned (example zone 1). Again connect Red wire to Pin A, Black
wire to Pin B and Bare wire to Pin C.
2, zone 3, etc.
1) Connect an RCA cable to the Audio Out jack [9] of AP-4 and connect other end to Audio In (or line in)
of VCR/DVR
2) To record, press the Zone Selector Switch [1] located on front panel of base station for the audio zone
to be recorded
3) For audio playback, connect another RCA cable from Audio Out (or line out) of VCR/DVR to Audio In
[8] of AP-4
4) Press in the Play/Mute Switch[1] of front panel
5) Press the play or playback button on VCR/DVR to start audio playback. Playback will be broadcast
through the base station’s built-in speaker. As an alternate playback may be channeled through a
CCTV monitor with amplifier or through DVR’s speaker system
2) If connecting to a DVR with multiple audio inputs or to a soundcard module:
AP-4 has 4 line level RCA Mic Output Jacks [11]
1) Connect RCA cables between the Mic Output Jacks [11] and Audio Inputs of DVR
2) For audio playback from base station (AP-4), press in the Play/Mute Switch[1] located on base
station’s front panel. Playback may also be channeled through other audio sources
3) To select a specific audio zone for playback, refer to DVR’s instruction manual
APPLYING POWER TO THE AP-4
A 12Vdc power supply is included with the above units. First connect the small end with the 90° plug to the above
units DC Jack[11] and connect large end to a standard 120Vac outlet or power strip.
Maximum distance between AP-4, etc. and Louroe microphones is 1,000 ft. (305m)

INSTALLATION AND OPERATING INSTRUCTIONS
OPERATION AND TEST
After microphones and power supply are connected, proceed as follows:
1) Turn on power to the unit by rotating the Power-Volume Knob[5] clockwise to “ON” position. The Power
Indicator LED [4] will illuminate, indicating power to the unit. Rotate Power-Volume Knob[5] further
clockwise to increase the volume of monitored audio.
2) Press Zone Selector Switch[2] marked zone 1. Audio from zone 1 should be present at the Monitor
Speaker[7]. The Zone Selector Switch[2] is lighted indicating audio for that zone is present. If there is no
audio, remove wires connected to Mic Input 3-Pin Terminal Block[6] for zone 1 at the rear of the unit. With a
DC voltmeter, check that 12 Vdc is present at terminals “A” and “C”. If voltage is not present, unit has a
problem with its power supply. If voltage is present, check to assure that wires are connected properly to the
right terminals. Otherwise microphone is defective. Call factory for assistance.
3) Repeat step 2 for the remainder of the zones.
4) When a recorder is connected to the unit, press Play/Mute Switch[1]. Switch lights up indicating unit is in
playback or mute mode. Start recording live audio. The Play/Mute Switch[1] must be depressed or in the
“OUT” position when a recorder is not connected to the unit.
5) Playback recorded audio through the AP-4, etc. built-in amplifier and speaker.
6) The Play/Mute Switch[1] can be used to mute the audio heard on the speaker. The orange light is On when
this switch is engaged. This function doesn’t mute the audio going to the DVR.

TROUBLESHOOTING
II. No audio present.
a. Using a DC Voltmeter, check the voltage across terminal “A” and “C” (”A” positive; “C” ground) of the Mic 3-Pin
Terminal Block[12]. It should read 12V. The microphone requires 12Vdc to work.
1) Check connections to the microphone.
b. Remove the wire connected to the “B” terminal of the Mic 3-Pin Terminal Block. Using an AC meter (set to
lowest voltage range), check the presence of audio from the microphone. Place the meter leads between wire
removed (positive) and terminal “C” (ground). Generate some loud noise close to the remote microphone
while observing the meter reading. If audio is present, the meter reading will start to fluctuate. If there is no
movement, the remote microphone is defective. Call factory for assistance.
Factory assistance is available between 8:30 AM to 4:00 PM Pacific time. Call (818) 994-6498.
