Description

Hold onto your seats. Our HCA-2205AT is one of the largest Home THX Ultra-certified amplifiers on the market without a noisy cooling fan. With five channels delivering 220 watts each, you can drive your front, center, and surround channels with explosive power and captivating grace. Stereophile Guide to Home Theater calls this "just about the perfect 5-channel home-theater amp.

FAQ

Where should I set the volume controls on the back of my amp?
Under normal conditions you should turn them all the way to allow full power output from your amp. However, if you need to match the volume output of one of our stereo amps with another brand (BiAmping) you could adjust them accordingly.
What does the "A" stand for at the end of the model name?
Auto-turn on. It means these amplifiers have 12V triggers that allow a preamp to activate them remotely. Some kind of triggering device is necessary for 12V activation.
What is the difference between the HCA-2205A and the HCA-2205AT?
The faceplate (and some necessary chassis modifications) is all we changed. The internal electronics are identical. Sorry, we cannot modify "A" versions to "AT".
