I have been using this for bi-amplification for years, but have now started using a different amplification system. Works perfectly. Just a little dusty. The thing is large and heavy, so shipping will be expensive.

For audio applications, the GFA-2535 in the 4-channel mode acts as a pair of 60 watts-per-channel amplifiers to drive two sets of speakers. With two of the channels bridged, it delivers 200 watts to a single subwoofer for an incredible display of musical strength so real you definitely can feel it.

Online description and specs: The Adcom GFA-2 stereo power amplifier features a stable, low-noise, low-distortion “front end” using differential FET amplifiers. The output stages of the GFA-2 use high-speed bipolar transistors, and entirely separate power supplies for the two channels enable each channel to deliver its maximum power regardless of the status of the other. The output transistors of the GFA-2 are fully protected against damage from short-circuits or overheating. The protective system disconnects the speakers by means of a relay, simultaneously changing a front-pan-el indicator light from green to amber. The same system delays the speaker connection for about 4 seconds each time the amplifier is turned on to allow internal transients to die away. The Adcom GFA-2 is rated to deliver 100 watts per channel to 8-ohm loads from 20 and 20,000 Hz with no more than 0.05 per cent total harmonic distortion. Its rated signal-to-noise ratio is 95 dB, and the input sensitivity is 97 millivolts (both figures relative to a 1-watt output in accordance with EIA Standard RS-490). The GFA-2 is 19 inches wide, 14 inches deep, and 5-1/4 inches high, and its front panel is slotted for rack mounting and fitted with handles for easier moving or lifting. It is finished entirely in black, with several small LED front-panel indicators and a large square pushbutton power switch. In addition to the protection light, there is a red power pilot light and two yellow peak lights that flash when the output voltage approaches the amplifier’s clipping level. On the rear of the amplifier there are insulated spring-loaded speaker connectors, phono-type input jacks, and two line-fuse holders (each power supply is separately fused). The GFA-2 weighs 29 pounds. Regularly Priced: $360.

For sale here is an Adcom GFA-2535 multi-channel power amplifier. This amp is great for surround sound systems as it offers the flexibility of either 2, 3, or 4-channel use. It offers 60wpc with all 4 used, or 200wpc to the bridged pair (as a single channel), with 60 to the other pair. If only 2 channels are used, it will be a 60wpc amp (8ohm impedance). This amp is used and is not cosmetically perfect, but is in perfect working condition. Per the photos, the most noticeable marks are on the top, in back. If this is placed in a cabinet of any kind, you will never notice them. The amp does not get hot (only slightly warm, in my experience), so cabinet placement shouldnt be an issue. Shipping cost is based on UPS Ground shipment. If you would like something else, please contact me before purchasing.
