Re: Yamaha RX-V490 Amp

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. :)

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.

Can I use an Ipod Dock with a Yamaha RX V490 receiver?

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.

Monitor problem

I don't see any OSD in the RX-V490 owner's manual. This unit only passes video through from a video source, like a VCR.

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.
