AUDIO DISTRIBUTION AMPLIFIER
INSTALLATION AND OPERATING INSTRUCTIONS
MODEL DA-4
DESCRIPTION
The Model DA-4 is an Audio Distribution Amplifier with one audio input and four
audio outputs. It receives line level audio signals from a Louroe base station or
Louroe microphone and distributes it to up to four devices such as DVR’s, VCR’s,
CCTV monitors with amplifiers or other audio devices that accept line level input.
Each output of the DA-4 has a gain adjust potentiometer for correcting audio level.
Maximum gain is 15dB when potentiometer is fully engaged. Included with the
DA-4 are five RCA connector cables and a 12Vdc power supply.

Microphone Connection to DA-4
a. Referring to the microphone 3-pin terminal block, connect a 22 gauge shielded cable to terminal B
and a ground wire to terminal C. (Terminal C is common for both 12Vdc power and audio output).
b. Run other end of cable to DA-4 and solder to an RCA plug. Wire from terminal B of microphone
goes to the tip of the RCA plug and ground wire goes to the sleeve.
c. Connect RCA plug to “Audio Input” RCA jack of DA-4

INSTALLATION AND OPERATING INSTRUCTIONS
Connecting a Louroe Microphone to a Louroe Base Station and to DA-4
a. If microphone is to be first connected to a Louroe base station, follow the instructions that accompany
the specific base station (APR-1) for making wiring connections
b. For connecting base station to DA-4 use supplied RCA cable and go “Audio Out” (RCA) of base station
to “Audio Input” of DA-4
Connecting DA-4 to Audio Receiving Devices (DVR, VCR, CCTV Monitor)
a. The DA-4 has 4 RCA audio out jack. Using supplied RCA cables connect “Audio Output” of DA-4 to
Audio in (or line in) of the receiving devices.
NOTE: Should audio receiving device (DVR, PC
soundcard module, etc.) contain a
3.5mm audio input ( or line input).
Connect an RCA to 3.5mm adapter to the
RCA plug and insert. Check
specifications or DVR, etc. to determine if
audio input is mono or stereo.
b. Apply +12Vdc power to DA-4 using the 120V/12Vdc power supply (included). Connect small 90° plug
into the 12Vdc power jack located on DA-4. Connect the two-pin large plug to a standard 120 Vac wall
outlet or power strip. The green power LED will illuminate.
c. Each of the four audio outputs has a gain adjust potentiometer. Using a small screw driver, the desired
level of audio can be obtained by rotating clockwise to increase, or counterclockwise to decrease.
d. Microphone sensitive switch. Located on the backside of microphone is a sensitivity switch marked N
(normal) and L (low). If application requires less microphone sensitivity, move slide switch to “L”
position. This will lower the gain (-6dB output into 600W).
