Because of the great amount of electrical energy stored in the capacitors, the design of the GFA-555 will
allow music to remain audible for several seconds after the amplifier has been shut off. We suggest that you wait
until the red power LED has stopped glowing before turning off your preamplifier and other components. This
procedure will prevent turn-off transients from reaching your speakers. During the shut down procedure, you may
hear small noises through your speakers which result from capacitor discharge. This is normal, and is no cause for

SAFETY WARNING
CAUTION: BURN-OUT OF THE OUTPUT STAGE BECAUSE OF FAILURE TO OBSERVE THE
PRECEDING AND FOLLOWING PRECAUTIONS WILL VOID THE WARRANTY!
There is no such thing as absolute reliability or protection when amplifiers are abused. While the GFA-555
amplifier has been designed to operate reliably under normal conditions, it may not be impervious to gross abuse.
There is one condition which must always be avoided: This condition is called RF Detection and because ADCOM
amplifiers have such an extremely wide band width, RF Detection will almost certainly cause failure of the output
devices if it occurs. Damage to, or failure of this equipment due to RF Detection is considered abuse, and is specifically
excluded from the ADCOM warranty. The following acts cause RF Detection and MUST BE AVOIDED:
1) Connecting the inputs or outputs while the amplifier is ON.
handle the amplifiers power output or any other misuse.
