INSTALLATION AND OPERATING INSTRUCTIONS
MICROPHONE ADJUSTMENT CONTROLS
On MLA-8 PC board are eight potentiometers (marked 1 thru 8) and one MASTER CONTROL marked “MAIN”.
They are for controlling the microphone gain and have been pre-set at the factory. DO NOT MAKE ANY
ADJUSTMENTS ON THE MLA-8 UNTIL ALL MICROPHONE AND SPEAKER CONNECTIONS HAVE BEEN
MADE TO THE LOUROE BASE STATION OR OTHER RECEIVING DEVICE.
A. If connected to a sound activated ALARMING BASE STATION (Models DG-25III and DG-12II):
1. First set zone threshold following procedures outlined from base station installation instructions.
2. If the zone is too sensitive and goes into alarm unnecessarily, adjust MASTER CONTROL
potentiometer on MLA-8 board (marked “MAIN”) 1/8 of a turn counterclockwise. If still too
sensitive, decrease by 1/8 turn counterclockwise until desired sensitivity is attained. In the
event zone is not sensitive enough, adjust master control potentiometer 1/8 turn clockwise.
Repeat if necessary.
3. If it is determined that a particular microphone within the zone is too sensitive, adjust the correct
potentiometer (marked 1 thru 8) counterclockwise 1/8 turn. Repeat 1/8 turn as necessary.
B. If MLA-8 is connected to a NON-ALARMING LOUROE BASE STATION (APR-1, AP-2,
AP-4, AP-8, AP-12TB or AP-16TB). Potentiometer adjustment is usually unnecessary.
EXCEPTION: If microphones are overdriving DVR/VCR or other external equipment, adjust master control
potentiometer 1/8 turn counterclockwise to reduce microphone sensitivity. Repeat if necessary.
