MICROPHONE CONNECTIONS TO AP-8

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-8, etc. and Louroe microphones is 1,000 ft. (305m)

CONNECTING AP-8 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.

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-8 Base Station location and connect to the 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.

A) If connecting to a VCR or to a DVR with one audio input:

1) Connect an RCA cable to the Audio Out jack [9] of AP-8 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-8

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-8), 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

SUMMARY

Please check that wiring and power connections conform to the above instructions. In the event of a malfunction, refer to

the troubleshooting guide, next page. Should the problem persist, factory assistance is available from 8:00 AM to 4:00

PM (Pacific Time) by calling (818) 994-6498.

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.
