INSTALLATION AND OPERATING INSTRUCTIONS
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@600W)
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.

INSTALLATION TIPS
1.Use overall shielded audio cable only. West Penn 452, Belden 8451 or
equivalent.
UNSHIELDED CABLE IS NOT SATISFACTORY FOR SOUND SYSTEMS.
2.When used at a cash register checkout, microphone should be installed
closer to the customer rather than the cash register, as the drawer sound
could dominate the recording. It should be installed closest to the area to be
monitored and documented.
3.Avoid installing microphone near air vents, air conditioners, fans and other
equipment that generate high sound and air pressure.
4.If microphone is installed in a police interview room, room should be
conditioned with any type of carpeting, acoustical ceiling tiles, acoustical
foam, etc. to reduce echo. This will enhance the quality of live and recorded
audio.
5.The APR-1 and microphone should have a barrier or solid wall between them
in order to avoid audio feedback, especially when they are in close proximity
to each other. If no barrier, microphone should be at least 25’ from APR-1 to
avoid acoustical feedback.
