Model A Microphone is designed for surface mounting to a ceiling or wall. Microphone will pick up
sounds 15’ away from all directions. For best results, install microphone as close to desired area of
coverage as possible. Avoid mounting microphone to ceiling heights in excess of 10’, or near air
vents, refrigeration units, or other audio interferences.
NOTE: Make wiring connection on back side of microphone before installing microphone to ceiling or
flat surface.
MICROPHONE INSTALLATION - ELECTRICAL
Located on back side of microphone is a terminal block marked A, B and C.
A is 12 Vdc
B is Audio
C is Ground (common)
Using recommended wiring, connect as follows:
RED wire to terminal A (12Vdc)
BLACK wire to terminal B (Audio)
BARE wire to terminal C (Ground)

The IF-1 Interface Adapter serves as an interface device between the microphone and the audio
receiver (DVR/VCR, PC sound card, etc.). The IF-1 can be installed several ways:
1) Wall mounted close to DVR/VCR or IP Network Camera, etc.
2) Attached to side of the receiving device using two-way ¼” adhesive tape
(not provided)
MICROPHONE CONNECTION TO IF-1 INTERFACE ADAPTER
Bring in other end of wiring from microphone and connect to “MIC INPUT” terminal block on IF-1
marked, A, B and C. Connect as follows:
Terminal A of microphone to terminal A of IF-1 12Vdc
Terminal B of microphone to terminal B of IF-1 Audio Output
Terminal C of microphone to terminal C of IF-1 Ground (common)
To apply power to the system, Model AD-1 12Vdc power supply is included. First connect small end
(female 90° plug) into 12Vdc jack on IF-1, then connect 2-prong power block to a standard 110Vac
outlet or power strip.
NOTE: Model IF-1 contains two types of audio outputs. A connection cable is provided for each
type.
1) RCA
2) 3.5mm stereo
3) RCA to 3.5mm mono with adaptor
These two audio outputs are in parallel ... only one can be used

3.5mm MONO TYPE AUDIO CONNECTIONS
To make connection to IP Network Camera, plug the RCA to 3.5mm mono cable with adaptor
(supplied) into the RCA audio out jack located on the output side of IF-1, connect other end of cable
(3.5mm) to the camera’s audio in jack (see drawing on page 5).
CONNECTION BETWEEN IF-1 AND A DVR, IP NETWORK CAMERA OR PC SOUNDCARD WITH
3.5mm STEREO TYPE CONNECTION.
To make connection, plug the 3.5mm stereo cable (supplied) into the “audio out” jack located on the

SENSITIVITY SWITCH OF MICROPHONE
For special installations that require less microphone sensitivity, a sensitivity switch has
been added to the microphone pre-amp (PC board) and has two positions - N and L:
N represents normal sensitivity (0dB output into 1KW)
L represents low sensitivity (-6dB output into 1 KW)
NOTE: Louroe™ Verifact microphones are always shipped with the sensitivity switch in
normal (N) position. Do not change unless required.
To make an adjustment, use a small screwdriver and move slide switch from N to L.
