ADCOM GFA-7705 5 CH Amplifier
Product Description
Product Description:
The conventional A/V receiver or its modestly powered multi-channel amplifier counterpart is fine for what it does. But it falls short if you want to reproduce the full explosive thunder of a movie house experience in your home.
To accurately drive and control serious loudspeaker designs of realistic live-sound levels in large volume spaces, the 'power and grunt' of Adcom's Big Rig power amps is a must.
The Big Rig design of Adcom's five-channel GFA-7705 will floor you with its fast, powerful, full-throttle sound. It delivers a real 200 watts per channel continuously into 8 ohms, or 300 watts into 4 ohms, at the rated bandwidth with extremely low distortion. And it is upgradeable to six or seven channels, too.

Product Description
The GFA 5400 replaces the GFA 545II and offers many of the same design features and sonic attributes of the enthusiastically received GFA 5802 and GFA 5500. The specifications should adequately describe all the pertinent information, including the increased power output into 8 and 4 ohms over the GFA 545II. As the 4 ohm power indicates, the current capability of the GFA 5400 has been substantially increased. The improvements are clearly audible with virtually all loudspeaker systems and will be appreciated by all who will use multiple 5400s in home theater systems.

Product Description
ADCOM's dedication to uncompromising sonic reproduction, innovative circuit design, and the highest quality electronic parts guarantee that, dollar for dollar, you're getting the best value in the audio world. At 300 watts per channel into 8 ohms and 450 watts per channel into 4 ohms, our new GFA-5802 combines innovative all MOSFET circuitry with a tremendous power supply to outperform any amplifier, even those selling for two to three times the price.To produce this remarkable amplifier, ADCOM started with an enormous toroidal power transformer. Totally separate secondary windings and independent ground connections ensure each channel is completely isolated. Lots of clean power for lots of clear and powerful sound. In addition to the GFA-5802's main toroidal transformer, a separate front end transformer is also used. This additional device isolates the front end input stages from the main output section so any peak demands from the output stages will not decrease the operating voltages for the input sections. This design also contributes to improved separation at the inputs for precise soundstaging and imagingElectronics:
