“What is the FTC power rating on this unit, 20Hz - 20KHz, all channels driven @ 8 ohms? It would be nice to know power bandwidth as well.”

I have seen ratings online of the power from 90 watts to 145 watts per channel. (145w x 7) at 20hz -20khz. I take all of that with a giant grain of salt. Consumer surround receivers like this simply cannot deliver that, especially when on the back of it, it is rated at 120v AC and 240watts. 145 watts x all channels for maybe a few milliseconds, not continuous. The most efficient of amps run at 90% efficiency, most at about 50-60 %, so when it draws 240watts from the outlet, where are the rest of the watts coming from? The power supply capacitors can supply higher power for momentary peaks, but not continuous power. It is also not listed as a high current amp, which you won't find at this price point. That all being said, this receiver sounds pretty darn good. Its ability to properly equalize different model speakers into one uniform sound field is simply remarkable. it is also fairly easy to setup, and the remote is more straight forward than the typical Yamaha remote. My Polks have never sounded so good for home theater use. But don't expect it to sound like a high current amp, or an amp from when watts were measured as real watts ( the 1970's ) ! For that you need to spend much much more.
Sorry, there was a problem. Please try again later.The listed specs are RMS to 6 ohms: 20 Hz-20 kHz, THD 0.09%, 90W + 90W minimum, Stereo Mode is 1 kHz, THD 1%, 105W + 105W, and Surround Mode is 1 kHz, THD 0.9%, 145W per channel.
