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.
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 600
W
).
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.
