Louroe Electronics APR-1 - Manual (Page 4)

WIRING CONNECTION TO THE LOUROE MICROPHONE
All LOUROE microphones have either a terminal strip or terminal block
Marked A, B, C.
A = 12 Vdc Power
B = Audio Output
C = Ground
If using recommended wiring connect as follows:
1) Connect Red wire to terminal A of microphone
2) Connect Black wire to terminal B of microphone
3) Connect Bare wire to terminal C of microphone
WIRING CONNECTION FROM MICROPHONE TO LOUROE APR-1 BASE STATION
Bring other end of cable to the APR-1 and connect as follows:
On the back panel of APR-1 is a 3-pin terminal block A, B, C.[13]
1) Connect Red wire to terminal A of APR-1
2) Connect Black wire to terminal B of APR-1
3) Connect Bare wire to terminal C of APR-1
APPLYING POWER TO MODEL APR-1 BASE STATION
Supplied with the APR-1 is a 12Vdc, 500mA power supply. Connect the small end to the 12Vdc Power Jack[10]
located on back panel of APR-1 first, then connect the 2-prong end to a standard 110V outlet. This will power up
the APR-1 plus send 12Vdc phantom power to the microphone when the Power-Volume Switch is turned on.
System performs best when there is an acoustical barrier (such as a wall), between the microphone and APR-1.
If no barrier, then microphone should be 25’ minimum distance from the APR-1. This is to avoid acoustical
feedback. If closer, a headphone should be used.
CONNECTING A MICROPHONE FROM OTHER MANUFACTURERS TO THE APR-1
If microphone is a brand other than Louroe it must:
1) Operate on 12Vdc power
2) Produce Line Level output (0dB@600
W )
NOTE: Microphones that produce mic level (-45dB) are not compatible with the
APR-1 Base Station
A. If microphone from other manufacturer requires power, refer to the microphone’s instructions for applying
power. For connecting microphone to the APR-1, there should be two connecting points on the microphone:
Audio Output
Ground
On the back panel of the APR-1 is a 3-pin terminal block marked A, B, C. Using a single conductor shielded
cable with a drain wire (ground wire)
1) Connect the shielded wire representing Audio Output of the microphone to terminal B of APR-1
2) Connect the drain wire representing Ground to terminal C of APR-1.
Terminal A of APR-1 is not used.
3) Using the APR-1’s power supply connect small end to the 12Vdc jack on APR-1 back panel and
the 2-prong end to a standard 110V outlet.
B. If microphone from other manufacturer is installed in a CCTV camera and draws power from the camera,
follow steps 1, 2 and 3 listed above.
