MICROPHONE INSTALLATION - MECHANICAL - MICROPHONE

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)

NOTE: If using wiring from other manufacturers,

color code may vary.

MECHANICAL - RN-2 AND IF-1

RN-2 and IF-1 can be installed to a wall or flat surface with mounting screws or by using a strong double backed adhesive
tape. They are usually located between the microphones and the receiving device such as a DVR or IP Camera.

WIRING CONNECTION FROM MICROPHONES TO RN-2

1) Bring in wiring from first Louroe microphone (or speaker/microphone) to INPUT side of RN-2 and connect as
follows:

1. Wire from terminal A of microphone goes to A of RN-2

2. Wire from terminal B of microphone goes to B1 of RN-2

3. Wire from terminal C of microphone goes to C of RN-2

RCA Audio Out Jack

2) Bring in wiring from second microphone (or speaker/microphone) to INPUT side of RN-2 and connect as follows::

1. Wire from terminal A of second microphone goes to A of RN-2

2. Wire from terminal B of second microphone goes to B2 of RN-2

3. Wire from terminal C of second microphone goes to C of RN-2

INSTALLATION AND OPERATING INSTRUCTIONS

CONNECTING RN-2 TO LOUROE IF-1 AUDIO INTERFACE ADAPTER

From OUTPUT side of RN-2, make connection to the Louroe IF-1 Audio Interface Adapter as follows:

1. Terminal A of output goes to terminal A of IF-1

2. Terminal B of output goes to terminal B of IF-1

3. Terminal C of output goes to terminal C of IF-1

Located on the output side of the RN-2 Mixer is an adjustment potentiometer for microphone balance. If more volume is

desired from microphone connected to the B-1 input side, turn potentiometer counterclockwise toward the B-1 arrow. If
more volume is desired from microphone connected to the B-2 input side, turn potentiometer clockwise toward the B-2
arrow. For equal volume from the two microphones, position potentiometer to the center.

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

CONNECTION BETWEEN IF-1 INTERFACE ADAPTER AND DVR/VCR WITH RCA TYPE AUDIO
CONNECTIONS

To make connection to DVR/VCR, plug the RCA cable (supplied) into the RCA type audio output jack located on the
output side of Model IF-1. Connect other end of RCA cable to the DVR/VCR’s “AUDIO IN” jack (see drawing on page

4).

CONNECTION BETWEEN IF-1 AND AN IP NETWORK CAMERA, DVR, VIDEO SERVER WITH

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 output side of IF-1.
Plug the other end of the cable to “AUDIO IN” of DVR, IP Network Camera or “ LINE IN” of PC soundcard (see drawing

on page 6).

NOTE: DISTANCE BETWEEN MICROPHONE AND IF-1 SHOULD NOT EXCEED 1,000’.

THE RN-2 MIXER GAIN IS LIMITED THAT IT MAY NOT SATISFACTORILY DRIVE
AN AUDIO LINE OF MORE THAN 1000’.

INSTALLATION AND OPERATING INSTRUCTIONS

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 1K? )

L represents low sensitivity (-6dB output into 1 K? )

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.

Sensitivity switch is located on the backside of Verifact™ A Microphone.
