Hi, has anybody used one? I have a stereo receiver which works fine but also have an amp (Carver THX 125 watts X 5, 180 watts X 2) not in use, thinking about trying the adapter and use the amp...

Something like this? Interesting - I was looking for just this thing a few hours ago. I got sidetracked putzing around with my computer settings etc and haven't bought a pair yet but I will be buying a pair. I need it to connect my Grace Digital internet radio to a small pair of speakers so I don't have to use the Flex Amp. I hate those RCA outlets for speakers. I'd rather they put spring loaded speaker terminals than RCA connections. Better yet would have been regular binding posts but it is what it is.

My idea is to go from the receiver speaker output to the rca input of the amp.

You typically cannot send a hi level signal to most home amplifiers rca level input, although I don't know much about the Carver amplifiers. This feature is common in car audio, usually because it can be difficult to get a low level signal from a stock head unit to an aftermarket amplifier. The voltage supplied by a high level signal will typically clip the input signal of a standalone amplifier. Best to get a new preamp with the proper low level outputs if you want to use your amplifier.

Receiver has no pre outs, I'll just forget the whole thing, it's just that the Carver has been sitting there since I got the XPA7, will see if someone will buy it, thanks for the replies.

By the way the receiver is in the living room.

Thanks guys, one more question, if I use this, when I turn the volume up on the receiver, is there going to be an effect by the receiver amp feeding the power amp? Just curious.

You're all sort of missing the point here.  Separate preamps and power amps almost always deliver better sound quality than the equivalents you have in a receiver. When you connect a receiver to a separate power amp, you're usually hoping for both more power and better sound quality. And, by using the preamp outputs - if it has them, you bypass the usually inferior power amps in the receiver. However, if you connect the speaker outputs of the receiver to the amp through an adapter, you're STILL going through the amplifiers in the receiver. This means that, while you get more power, the noise and distortion from the receiver's amps will also be added to those produced by your new power amp. How significant this is will depend on how bad those amps really are - but some are pretty bad. So, in general, you REALLY want to avoid doing it that way unless there is absolutely no choice. Connecting things that way as an "emergency" temporary measure, until you can get a preamp or pre/pro, will work. But it isn't at all a good way to put together a good sounding system. |

Wow, I never thought this would even work without blowing up a amp. I had once read it would be like driving a Mac truck though a mouse hole. Not that I would ever do this it just does not seem like a good long term option. |

I'll forget the whole thing, the receiver is in the living room, don't do much listening there, it's just that the Carver is not being used, I don't want to invest in anything just to use it, I'll sell it to someone who will appreciate and take care of it, thanks guys.
