    Thank you for your reply and explanation. The reason I was asking is because I think that the new RX-V659 model will except a seperate amp (If I understand it correctly). I am not for sure though. I want to buy a GAS Son of Ampzilla amp and be able to use the RX-V659 as a pre-amp. Is it possible to do this or is it the same as my RX-V490?

The easy answer...

Absolutely NOT.

This is by all means a standard receiver. It in itself is an amplified unit. You would have to run the speaker ports to the input ports on the second unit.

If you do that, you'd have all kinds of problems. The most likely one being that you'd simply overload the input ports on the other unit.

It is never a wise idea to amplify an output signal into another unit that is just going to amplify it again anyway.

The bigger thing to keep in mind is that the input ports on the second unit just are not designed to take that kind of wattage. They're designed to take a few mW to a few W at most. Y'know?

I realize it's called an "amplifier" and all, but it's only meant to amplify the source signal to a level where it's audible through speakers.

A 'true' amplifier is meant to amplify a signal into a high-power monitor; such as a guitar amp, etc.

Please don't try to do this. I'd hate to see you lose a perfectly good receiver to something like that! :P

Good thinking, though. At least you're thinkin' up ideas on how to improve something. :)

    Ah. You had not mentioned another model number before...

    Also, we get confused on the terminology. You see... There are "amplifiers" and then there are "receivers".

    Both of these systems are technically "receivers".

    But looking at the manual for the RX-V659, I now see what you are intending to do.

    You're intending to use the Ampzilla to power the speakers. But you're going to use the RX-V659 as the pre-amp.

    It could honestly work. I was under the impression that you were wanting to link two RECEIVERS together; using one of them as the pre-amp into the other.

    Oddly enough, I looked at the manual for the RX-V659 and found that it has pre-amp inputs for each channel. But it looks like they use specialized amps for each channel. The RX-V659 must be one mean machine to be using pre-amp inputs.

    But you want to link the RX-V659 to the Ampzilla from what I am now interpreting.

    I don't see why you couldn't. You'd just run the speaker outputs from the RX-V659 to the inputs on the back of the Ampzilla. I'm not sure how many channels the Ampzilla is capable of using. I would assume only two, of course. But it's doable.

    You'd just have to be sure to moderate and balance the two systems. Don't put too much current from the speaker outputs of the RX-V659 to the inputs on the Ampzilla. The problem with running a setup like that is that the RX-V659 is not designed to operate like that. There could be frequency or resistance differentials that you may or may not be able to balance properly or compensate for. You may wind up with distortions, etc with the end result.

    Hard to say. But if you do try it, post your results. I'd be interested to see how it works.

    Hell... I can't honestly say that I've never done what you're talking about doing before. I used a basic 1,000-watt guitar amp system to increase the output from a receiver...which had a Nintendo 64 connected to it. We used it to amplify Goldeneye 64 to a bass amp and about 6 monitors. *laughs*

    Man... THOSE were the days!

    Anyway... Yeah. Let me know what you come up with. :)

    Good luck.

    The best I can tell you is you're going to have to experiment. If it sounds good and you don't get any interference or crosstalk, etc... Then it's probably a workable setup.

    By the way...

    If we are done here for the time being, how about a rating for me? :)

    Either way, just post your results. *nods*

    Hope the rating is good. (If I've sufficiently answered your questions, go ahead and give a "Solved" rating to indicate that we have arrived at a solution.)

Sound center


Replace center channel speaker with known good one. If no longer scratchy then the voice coil of removed unit is rubbing against the magnet pole and the speaker needs to be replaced. If the replacement speaker also sounds bad, then the amp for the center channel needs repair.

No, but you could still access the audio directly from the iPod...

Anything that has a headphone output can be adapted to feed an RCA cable pair for standard stereo to an amp or receiver. Get a cable like the one described here:

and connect it into any available analog input EXCEPT "Phono". Turn the MP3 player volume up.

My RX-V490 Amp. has no audio from Centre speaker.


Is your center mode set to "Phantom" instead of "Normal" or "Wide"? That would split the mono Center channel program and mix it equally with the programs for both front speakers so your brain would believe it's in the center.

Can you run 200watt 6ohm speakers on the RX-V490


Hi I have just read the specs on about your Yamaha system and you cant run 6 ohm speakers to your amp. You have to impedance match the speakers and the amp otherwise the speakers will "blow". So you need some 8 ohm speakers, the wattage of the speakers doesn't particularly matter as long as they are not too weak or too powerful becasue the amp will drive the speakers no matter what but if the speakers are of a low wattage then the amp could blow the speakers if it is turned up too loud. The specs of your amp are given in the link below.

Yamaha RX V490 Turning itself Off


The amp is in protect mode which means that the output section has a problem. With nothing connected, there are defective parts inside the unit. This type of problem is not likely to have been caused by any shipping damage. I would guess that the output transistors are shorted.
