ACTIVATION OF THE THERMAL PROTECTION CIRCUITRY IN THE GFA-555ms IS AN
INDICATION THAT THE AMPLIFIER HAS BEEN OVERDRIVEN OR THAT THE LOAD
THE LOUDSPEAKERS ARE PRESENTING TO THE AMPLIFIER IS UNREASONABLY
LOW. IF YOU WISH TO PREVENT RECURRENT ACTIVATION OF THE THERMAL
PROTECTION CIRCUITRY, YOU MUST REDUCE THE VOLUME LEVEL DEMANDS,
RECTIFY THE LOAD-IMPEDANCE CONDITION WHICH MAY BE CAUSING
ACTIVATION OF THIS CIRCUITRY, INSTALL AN AUXILIARY FAN OPTION OR, IN
EXTREME CASES, UNDERTAKE ALL THREE.
CARING FOR YOUR GFA-555ms
Great care has been taken by ADCOM to assure that your amplifier is as flawless in
appearance as it is electronically. The front panel is a heavy- gauge, high-grade aluminum
extrusion carefully finished and anodized for durability. The chassis, top cover and rear
panel are of heavy-gauge steel, both painted and baked. If the front panel, top or sides
should become dusty or fingerprinted, they can be cleaned with a soft Iintless cloth, slightly
dampened with a very mild detergent solution or non-ammonia glass cleaner.
NOTE
DO NOT SPRAY OR USE LIQUIDS OF ANY KIND ON THE SURFACES OF THE
GFA·555se. DO NOT EXPOSE THE AMPLIFIER TO RAIN, WATER OR MOISTURE OF
ANY KIND.
