GFA-7400

    Creating the big, room-filling sound of a true home theater system doesn't mean you need an oversized amplifier.  That's why ADCOM's GFA-7400 Five-Channel Power Amplifier was specially designed for the home theater customer who needs a smaller yet powerful source for multi-channel home theater sound.

Powered by an enormous toroidal transformer with multiple secondary windings, the GFA-7400 is capable of driving 100 watts RMS into all five channels simultaneously.  Power of this magnitude is usually only achieved by connecting multiple amplifiers. But with the GFA-7400 you get all that power in a compact package at an affordable price.

Listen to a home theater system built around a GFA-7400 and you'll hear a level of clarity, imaging and depth that can only be found in amps costing two and three times as much.  Its uncompressed dynamics and distortion free sound field make the most of any size room.  The GFA-7400 adapts to fit your environment, so every entertainment event sounds as large and dynamic as the original performance.

And because it's an ADCOM, the GFA-7400 is as easy to use and understand as it is pleasurable to hear.  All RCA input connections are gold plated for the highest quality sound reproduction and all controls are ergonomically configured for easy operation.

Dollar for dollar there isn't another five channel, home theater amplifier that can deliver this level of power, performance and sonic integrity. With ADCOM components, great sounding home theater is in the details.
