GFA 7000

GFA-7000

Today's movie soundtracks demand more than conventional home audio systems can deliver. That's why ADCOM developed the Home THX-certified GFA-7000 power amplifier.

To earn THX certification, an amplifier must deliver clean, powerful sound effects, dialogue and musical scores under all room and speaker-load conditions. But ADCOM's engineers went beyond the stringent requirements of THX and created a home theater power amplifier that meets the demands of the world's most critical audiophiles as well.

The GFA-7000's five mono modules produce 130 watts into 8 ohms and over 200 watts into 4 ohms from all five channels. This "five-mono-amplifiers " design guarantees the sonic integrity of each channel by completely eliminating inter-channel cross-talk and ensuring full-power with low-distortion from each individual channel, regardless of speaker impedance or efficiency.

The GFA-7000 features a heavy-duty 2000 watt toroidal power transformer with five separate secondaries. In addition, the120,000mF total storage capacitance bank will easily deliver the large amounts of current demanded by today's power-hungry, low-impedance THX speaker systems. This oversized and generous power supply allows maximum power output over a wide and unrestricted dynamic range of the ever-increasing number of digital audio and audio/video recordings.

And because ADCOM designs products for tomorrow as well as today, the GFA-7000 has been designed to meet all the new Dolby AC-3 requirements, including full-bandwidth response down to the lowest frequencies.

You can be sure, whether you're listening to movies or music, theGFA-7000 is the perfect choice for any stereo or multi-channel home theater system, especially if you want the movies you play at home to sound as live and exciting as their filmmakers intended. Leave it to ADCOM - two thumbs up for performance and value.
