DESCRIPTION
Models AP-2, AP-4 and AP-8 are non-alarming audio monitoring base stations for providing 2, 4 and 8 audio zones.
Each model has the same amount of audio outputs (RCA) as it does for microphone inputs. Example: Model AP-4 will
accommodate four Louroe Microphones and has four line level audio outputs. All models contain a built-in speaker for
producing live audio and audio playback from a DVR. In addition, each model contains a selectable RCA audio output for
interfacing with a DVR with only one audio input, or with a VCR. Zone selection is by pushbutton. All Louroe
microphones are compatible with the AP-2, AP-4 and AP-8.

[6] - Filter Switch Normally used when playing back audio from a Time Lapse
recorder. This function is no longer available on this product.
[7] - DVR/VCR-IN Switch Press to connect DVR/VCR into the unit. Depressing switch
bypasses the DVR/VCR even if it is connected physically to the
back of the unit. This eliminates the need to disconnect the
DVR/VCR when not in use.
[8] - Power-Volume Control Knob Rotating knob clockwise turns on power to the unit, as indicated
by the Filter-OUT Indicator[2]. Rotating further clockwise
increases the volume of the monitored audio produced through
the Monitor Speaker[10].
[9] - Headphone Jack (3.5mm stereo) Used for private listening. Any monaural headset with 8 to 600Ω
impedance maybe used. Mutes the speaker output when in use.
DESCRIPTION AND FUNCTION OF PARTS
[1] - Zone Selector Switches Selects zone for monitoring. Press switch of desired zone to
listen to live audio. Pressing more that one switch is possible
when it is necessary to monitor more than one zone at a time,
but audio may be difficult to understand if there is audio activity
at several zones.
[2] - Filter-OUT Indicator Lights (green) when audio filter is not in use. Indicates power is
“ON”.
[3] - Filter-IN Indicator Lights (red) when Filter Switch[6] is pushed in to “ON” position.
[4] - DVR/VCR-IN Indicator Lights (yellow) when DVR/VCR switch[7] is pushed in to “ON”.
[5] - Overload Indicator Lights (red) when a short or overcurrent in the power supply
occurs. If this occurs, turn OFF the Power-Volume Knob[8] and
check wiring connections (see troubleshooting, pg7).

MICROPHONE CONNECTIONS TO AP-2, AP-4 OR 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-2, etc. and Louroe microphones is 1,000 ft. (305m)
CONNECTING AP-2/AP-4/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-2, AP-4 or 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 [13] of AP-2/AP-4 or 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
[14] of AP-2/AP-4/AP-8
4) Press in the VCR Button [7] 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-2, AP-4 and AP-8 have 2, 4 and 8 line level RCA Mic Output Jacks [15]
1) Connect RCA cables between the Mic Output Jacks [15] and Audio Inputs of DVR
2) For audio playback from base station (AP-2, etc.), press in the VCR IN button [7] 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 [phone].
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[8] clockwise to “ON” position. The green LED
[2] will illuminate, indicating power to the unit. Rotate Power-Volume Knob further clockwise to increase the
volume of monitored audio.
2) Press Zone Selector Switch[1] marked zone 1. Audio from zone 1 should be present at the Monitor
Speaker[10]. If there is no audio, remove wires connected to Mic Input 3-Pin Terminal Block[12] 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 regulator. 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 DVR/VCR-IN Switch[7]. DVR/VCR-IN indicator[4] will light.
Start recording live audio. The DVR/VCR-IN Switch[7] must be depressed or in the “OUT” position when a
recorder is not connected to the unit.
5) Playback recorded audio through the AP-2, etc. built-in amplifier and speaker.

TROUBLESHOOTING
I. Overload Indicator
a. When the Overload Indicator is illuminated, it is an indication that there is a short in wiring
connections to the microphone. Check the following:
1) Check that each wire is connected to their proper terminals See steps 1 and 2 of
connections page 5.
2) Check that there are no reversed or crossed wire connections.
3) Check that none of the wires are touching each other or shorted to ground.
b. Turn ON power back to the unit after checking all wiring connections. If the Overload
Indicator[5] no longer lights, proceed to step 2 of the operation. If the Overload Indicator
remains illuminated, remove the microphone connections (power still ON) one at a time until the
Overload Indicator turns OFF. After removing a wire, wait a few seconds before removing the
next wire. This will give the overload protection circuit time to reset itself. The last wire
disconnected that turned OFF the Overload Indicator is the one that has a short. Check for
shorts on the wire and remote microphone.
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 [phone].
