GFA-7300

   Creating a big space, room-filling sound of home theater in a smaller space doesn't require a large amplifier.  That's why we offer ADCOM's GFA-7300 Five-Channel Power Amplifier, designed for the home theater customer who needs a smaller yet powerful source for multi-channel home theater sound.  Modeled after the larger GFA-7500 and GFA-7400 amplifiers, the GFA-7300 perfectly drives smaller systems with all the superior sonic characteristics of its bigger brothers, with all the dynamics at a lower power level.

Powered by an oversized toroidal transformer with multiple secondary windings, the GFA-7300 is capable of driving 60 watts RMS into all five channels simultaneously.  Unlike many receivers, this is clean, high current power, exactly what you need to deliver all the impact and dynamics of home theater sound.  With the GFA-7300 you get dynamic power in a compact package at an affordable price, with all the advantages of separates for the ultimate in multi-channel sound.

Listen to a home theater system built around a GFA-7300 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 smaller size rooms.  The GFA-7300 adapts to fit your environment, so every entertainment event sounds as large and dynamic as the original performance.  For many people the GFA-7300 is the perfect power solution.

Because it's an ADCOM, the GFA-7300 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.
