Q: Can i bi amp my tower speakers off this amp while its connect to my av receiver
A: Hello and thank you for your question. This will depend on the AV receiver. Example, the Marantz PM8006 will allow Bi amp as it will output power from the speaker A terminal while outputting a signal via RCA pre out the external amp. Connect the high pass from to the PM8006 and low pass to the external amp.
A: The latter is correct. All channels can produce 140 watts per channel, just not all at once.

Purchased this to augment my 9-channel receiver in an 11-channel system (I was using an old Insignia stereo receiver to power the rear Atmos/ceiling speakers). Easy to setup, the trigger input works well to turn on the amp automatically when the receiver turns on. Using it to power the front L&R, center, and rear surrounds. Sound quality is good. Surprised that I have to turn the volume up to the same levels as before; since the Denon receiver is 140w per channel into 2 channels, I was expecting the 140w per channel of the Marantz to play louder, but it doesn't.

I added the Marantz MM7055 to my Denon AVRX 6700, 5.2 setup with SVS Ultras. I was content prior to adding the amp, but I'm so happy I added the amp. Such an improvement in sound quality. My SVS Ultras are running off the amp leaving the 6700 to power my 2 SVS subs. Cleaner, more defined sound with appropriate umph. My only regret is that I didn't get the MM 8055 for more power.

A great addition to my home theater. I purchased this amplifier so i could add a 2nd pair of dolby atmos in ceiling speakers to my theater room to run 7.2.4 and everything is perfect! I use the amp to run my front stage and rear surrounds and have my avr power the rest, couldn't be happier.
