Axiom Home Page Forums General Discussion Technical Questions Connecting Hifi system to HT system

Hello everyone
I need your opinion on connecting two receivers to the same amp.
Basically, I need to connect two systems to the same amplifier and front speakers.

I have a yamaha Rx-v3800 receiver, a Rotel Rc-1070 pre-amplifier, a rotel Rb-1070 stereo amplifier and a rotel Rcd-1072.
As or now, my M80s are connected to the Rb-1070

The Front speaker Preout of the Yamaha are connected to the AUX input of my rotel pre-amp.

The pre-amp output is connected to the Rotel stereo amp.
The cd player is connected to the CD input of the pre-amp.

This way, when I want to use the front speakers with the yamaha receiver, I set the rotel pre-amp to AUX and when I need the speakers for the cd player, I simply set it to CD.

The rotel pre-amp input can handle up to 5 volts before they being to saturate but I was told my method of connecting everything together would not insure Unity gain. I'm not sure what is meant by unity gain and I was wondering if you guys had better ideas on how to connect everything together.

Thanks

I think an important question here is why?

Because intially, I was going to connect my m60s to my HT receiver and get m80s for my other system but I ended up upgrading my m6os for the 80s and the yamaha receiver can't handle the 4ohms load. So I need to use my stereo amp for the m80s.

When I bought the rotel cd player, the Rotel rep told me that going through the yamaha pass-through would alter the signal. So i was told to switch the interconnects to the Rotel amp input between the rotel pre-amp and yamaha receiver depending on if I wanted to listen to cds or watch movies. It wasn't a great solution so I tried to connect everything together until I get new speakers,new amp and separate both systems again.

Have you tried the yamaha with the m80's? Are you sure that it can't handle the 4 ohm load?

Sounds like the Rotel rep was trying to sell you more Rotel gear. Was he specific on how the Yamaha would alter the signal?

Use the Yamaha by itself and the Rotel gear by itself.

yeah, I tried the m80s with the yamaha and it shuts down after a few minutes at medium volume.

I was told by the Rotel people that I could connect the L & R preouts of the Yamaha to the aux inputs of the RC-1070 and my amp to the “Tape 2” output of the RC-1070. Then by setting the “RECORD” selector to “AUX” I would then be able to select any source on the Yamaha and have the signal passed through the preamp.

In the end I might just retire my pre-amp until I get a new set of speakers.

I wonder if there is something wrong with the 3800 as there are others using the same receiver with M80s and no issues, but this is the reason why Axiom doesn't recommend Yamaha with M80s.

I agree with St. Patguy here... the Yamaha's not going to alter the signal unless you use a surround mode or something.

Couldn't you use the Rotel amp for the mains from the Yamaha pre-outs?

I can't see the Yamaha noticeably degrading the signal from the CD player.

I think the Rotel pre-amp is surplus. Or, sell it and the Yamaha and get an integrated multi-channel processor solution.
