Question about Yamaha RX-V490 Receiver
Can I use a seperate amp and use this unit as a pre-amp?
The easy answer...
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. :)

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.
