Louroe Electronics DA-8 User manual

DESCRIPTION
The Model DA-8 is an Audio Distribution Amplifier with one audio input and eight
audio outputs. It receives line level audio signals from a Louroe base station or
Louroe microphone and distributes it to up to eight devices such as DVR’s, VCR’s,
CCTV monitors with amplifiers or other audio devices that accept line level input
(0dB @ 600W). Each output of the DA-8 has a gain adjust potentiometer for
adjusting audio level. Maximum gain is 15dB when potentiometer is fully
engaged. Included with the DA-8 are nine RCA connector cables and a 12Vdc
power supply.

INSTALLATION AND OPERATION
1) Connecting a Louroe microphone directly to the DA-8
(Refer to figure 3, page 5 of this instruction)
All Louroe microphones contain a 3-pin terminal block marked A, B, C
A = +12Vdc power red wire
B = Audio Output black wire
C = Ground bare wire
2) Microphone Connection to DA-8
a. Referring to the microphone 3-pin terminal block, connect a 22 gauge shielded
cable to terminals A, B and C. Using the recommended cable connect RED wire to
A, BLACK wire to B and BARE wire to C.
b. Run other end of cable to the DA-8 3-pin terminal block also marked A, B and C.
Connect RED wire to A, BLACk wire to B and BARE wire to C (shown in the
diagram)

4) Connecting a Louroe Microphone to a Louroe Base Station and to DA-8
(Refer to Fig 2 on page 4 of this instruction)
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-8 use supplied RCA cable and go “Audio Out”
(RCA) of base station to “Audio Input” of DA-8
5) Connecting DA-8 to Audio Receiving Devices (DVR, VCR, CCTV Monitor)
a. The DA-8 has 8 RCA audio out jack. Using supplied RCA cables connect “Audio
Output” of DA-8 to Audio in (or line in) of the receiving device.
b. Apply +12Vdc power to DA-8 using the 120V/12Vdc power supply (included). Connect
small 90° plug into the 12Vdc power jack located on DA-8. Connect the two-pin large
plug to a standard 120 Vac wall outlet or power strip.
c. Each of the eight 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
1KW).
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.
The 2 pin-terminal blocks can be use instead of
the RCA output jacks if the distance between the
DA-8 and receiving devices are far.
