CONNECTING VERIFACT C MICROPHONE TO A LOUROE RECEIVING DEVICE (BASE
STATION OR AUDIO INTERFACE ADAPTER)
After microphone connection has been made, run 2 conductor shielded cable to the Louroe Base Station or interface
adapter.
If Louroe Base Station is AP Series, DG-12/25 series, IF-1, IF-4 or IF-8:
RED Awire to terminal of base station
BLACK B wire to terminal of base station
BARE C wire to terminal of base station
NOTE: If DVR’s audio input is 3.5mm (1/8”port), a 3.5mm adapter must be connected to one end of the RCA cable.
Check DVR manufacturer’s instructions to determine if 3.5mm audio input is mono or stereo.
CONNECTION VERIFACT C MICROPHONE DIRECTLY TO A DVR OR IP CAMERA
If a Louroe Audio Base Station or interface adapter is not used and Verifact C is to be connected
directly to a DVR or soundcard, etc. use the following procedures:
1) Apply 12 Vdc (100 mA minimum) to PC board’s terminals A and C, A is positive, C is
ground
2) Run a single conductor shielded cable 22 gauge with a 24 gauge drain wire to DVR or
IP Camera
3) Solder on an RCA connector with wire from terminal B of microphone going to the tip
of the plug, and wire from terminal C of microphone going to the sleeve of RCA plug.
4) Connect RCA plug into “Audio In” jack of DVR or other receivers.
Microphone pre-amp is mounted in a protective plastic housing with openings for wire connection and microphone
sensitivity adjustment. If microphone is to be mounted in a special housing, a black grommet is included for optional use
in securing the microphone element to the inside of a camera housing or special housing. A 1/8” minimum opening must
be provided for microphone pickup. Microphone should be located within 4’ to 6’ of the subject. Avoid ceiling mounts
in excess of 10’ in height.
MECHANICAL INSTALLATION
Verifact C Microphone will connect directly to any Louroe Base Station (AP Series, ALA Series or DG Series) or to the
IF-1, IF-4 or IF-8 Interface Adapters. A small terminal block is located on the microphone pre-amp, and marked A, B, C:
A represents 12 Vdc (positive)
B represents Audio (Mic output)
C represents Ground (negative)

MICROPHONE SENSITIVITY SWITCH
The microphone pre-amp (PC board) contains a sensitivity switch with two positions:
N represents normal sensitivity (zero dB @ 1,000)
L represents lower sensitivity (-6 dB @ 1,000)
Microphone is always shipped in the N position. For less microphone sensitivity,
move slide switch to L position. Do not change unless required.
INSTALLATION TIPS
1. Use overall shielded audio cable only. West Penn 452, Belden 8451 or equivalent.
UNSHIELDED CABLE IS NOT SATISFACTORY FOR SOUND SYSTEMS.
2. When used at a cash register checkout, microphone should be installed closer to the customer rather than the cash
register, as the drawer sound could dominate the recording. It should be installed closest to the
area to be monitored and documented.
3. Avoid installing microphone near air vents, air conditioners, fans and other equipment that generate
high sound and air pressure.
4. If microphone is installed in a police interview room, room should be conditioned with any type of carpeting, acoustical
ceiling tiles, acoustical foam, etc. to reduce echo. This will enhance the quality of live and recorded audio.
5. The APR-1 and microphone should have a barrier or solid wall between them in order to avoid audio
feedback, especially when they are in close proximity to each other. If no barrier, microphone should be at least 25’
from APR-1 to avoid acoustical feedback.
2 Conductor cable, 22 shielded
gauge with a 24 gauge drain wire
NOTE: Unshielded cable is not
satisfactory for audio systems
