Hooking up 4 mono blocks

[Sydney's Dad]

Well I have two more Sony amps that are due here on Wednesday. That wil make four. Each mono block runs at 300 WPC or in stereo at 120 WPC. I had planned on hooking one amp up to each of my four front mains (RTi150 & Rti70). Any suggestions on the best way to set them up? I'd planned on using the receiver to power the center and rear speakers. The Receiver I'm using is Sony DA777ES and makes 125 WPC. Any help would be appreciated as I've yet to hook up external amps to any of my home systems.

How do you have your mains arranged? Do you intend to listen to both pair at the same time? Even for movies?

If so, I'd just recommend some decent y splitters. Especially if you can control the output of each pair of amps.

My room is fairly large(38 x 17) . I have the 150's in front, the 70's on the side wall. I do listen to all four since the majority of time I am rarely seated in the center of the room when listening to music. I do normally shut off the sides for movies and sacd's.

With that setup driving the RTi150 and RTi70 how would you balance the sound so that one pair of speakers don't overwhelm the other? The volume control on the preamp would globally affect both sets of speakers. One solution would be if the amps had a volume control like the Parasound amps do.

I have a gain control knob of the front of each amp. With only one speaker to each amp, I assumed that I could dial each speaker in and the receiver would handle the rest.

You presume correctly, the gain adjustment would be used to compensate for volume differences. The Parasound series work in the same basic way.

That is a cool little amplifier, nothing like vintage Sony ES. :D

Thinking about selling my RT20p and RTi70's and picking up another pair of RTi150's. Guess I could put 300 watts on each one of the 150's and see if I can find another TA-N55ES for the center.
