MICROPHONE CONNECTIONS TO 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 Power Jack[10] and connect large end to a standard 120Vac outlet or power strip.
Maximum distance between AP-2, etc. and Louroe microphones is 1,000 ft. (305m)
CONNECTING AP-4 TO A RECORDING DEVICE (DVR, ETC.)
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. Using sample cable:
A = 12Vdc Power (red wire)
B = Audio Output (black wire)
C = Common Ground (bare wire)
1) Take one end of recommended cable to first microphone location and connect:
Red wire to terminal A (12Vdc)
Black wire to terminal B (Audio Output)
Bare wire to terminal C (Ground)
2) Run other end of cable to the AP-4 Base Station location and connect to the Mic Input 3-Pin Terminal Block
of the audio 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.
3) Repeat the same procedure for the remaining microphones using the additional terminal blocks marked zone
2, zone 3, etc.
[6]
A) If connecting to a DVR with one audio input:
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 a particular zone, press the Zone Selector Switch [2] 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

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 green 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 switch blue light should be ON indicating that zone is activated. 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 defective 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]. The Play/Mute Switch[1] will light. The
audio from the remote microphones are muted. Press DVR playback switch to listen to recorded audio on the
unit’s speaker. The Play/Mute Switch[1] must be depressed or in the “OUT” position to hear live audio again
