IF-4 AUDIO

INTERFACE ADAPTER

(four audio inputs and outputs)

The LOUROE IF-2, IF-4 and IF-8 are two, four zone and eight

zone audio interface adapters designed for connecting up to

two (IF-2), four (IF-4) or eight (IF-8) Louroe microphones with:

! DVR’s

! IP Network Cameras with audio inputs

! Video Servers with audio inputs

! PC Sound Card Modules

The input side of the IF-2/IF-4/IF-8 has terminal blocks for

receiving the wiring from the microphones. The output side

has two types of output:

These three units also contain individual “audio level control”

potentiometers for audio gain adjustment. Output from the

Louroe microphone can be increased 10dB or decreased 30dB.

All Louroe microphones contain a terminal block

marked A, B, C

A = 12Vdc power (Red)

B = Audio output (Black)

C = Ground (Bare)

If using recommended wiring, connect as follows:

Red wire goes to Terminal A of microphone (12Vdc power)

Black wire goes to Terminal B of microphone (Audio Output)

Bare wire goes to Terminal C of microphone (Ground)

After all microphones have been connected, bring other end of wiring to the IF-2/IF-4/IF-8

location and connect each microphone to the terminal blocks of the unit marked A, B, C. Be

sure to properly match wire colors. If using cable from other manufacturers, color code may

vary.
