Description of Unit
The GFA-7705/07 is a
20-Amp
Device.
The GFA-7705/07 is high-power, high-current, wide-bandwidth design employing ADCOM’s Fast Analog Transform
(F.A.T.) circuitry with direct-coupled Power Rig output stages. All channels are completely monaural from
transformer secondaries through the output stages.
In order for this product to achieve its actual rated power output on all channels and to avoid repeatedly
throwing/popping the related electrical service panel circuit breaker, it is critical that the ampli er be
professionally installed on a 20-Amp household AC circuit and outlet, preferably dedicated but at minimum one
not shared with other large current-draw appliances or devices.
Common 15-Amp household circuits are easily and inexpensively converted to 20 Amp con guration by any high-
voltage licensed electrician.
For this reason, the GFA-7705/07 ships Factory-equipped with a hard-wired, 20-Amp Plug on the AC Power Cord.
WARNING:
DO NOT DEFEAT THE 20-AMP PLUG OR HARDWIRED AC POWER CORD TO EMPLOY EITHER A 15 AMP
OUTLET OR “AUDIOPHILE” TYPE DETACHABLE POWER CORD.
