Convert A/V Output to Input?

Question

So I'm currently working on a mechanism with my speakers but am in a jam. I need some sort of machine that recieves (input) A/V chords (really only the audio chords, red and white) and then converts the audio to speaker chords (for common speakers, red and black). My plan was to use a portable DVD player since there I can just run the audio chords in and then simply cut out the existing speakers and reroute it to my mechanism. My only problem is the two DVD players I'm using only have outputs (to make them act as DVD players for larger tvs). My question is can I possibly rewire anything (or just override the output) to convert the A/V output to an A/V input?

Answer 1

I THINK I understand, but am not sure (Your terminology is ... shall we say, unusual (!).

It sounds like you want to take a low level audio signal (red and white??) as an output from something (?) and turn it into a high level signal (red and black??) as input to speakers. If so, rewiring isn't the answer, the "mechanism" you need is an audio amplifier.

I'm not sure what a portable DVD player has to do with it, unless it is your intent to pass the low level (red and white?) signal to an auxillary input on the DVD player (if it exists) and then use the internal amplifier that powers the headphones (?) to power speakers.

A DVD player is not going to help you (although it could be the device that provides the A/V signal as input (white and red??) to your "mechanism"), even if you could jury rig an input, the headphone amplifier won't do what you want.

As I said before, I believe you need an audio amplifier (or if there is a video signal to be handled too, an A/V amplifier/receiver). They can be purchased for as little as about $20 - $50 at a used equipment store. Or you could do some research and build one from components purchased at an electronic parts store. I'd suggest the purchase route.

Alternatively, you could try wiring your low level signal (red and white) to the input of a pair of computer speakers (the type with a built in amplifier and volume control). You would need a suitable adapter (dual RCA jack to mini-stereo jack probably) to make the connection, unless you wire directly. Impedence mismatches could result in poor results, but it might work.

Good luck.

Answer 2

You realize the A/V are regulated power. Meaning you can only get sound at certain frequency. The speaker wires red/white are not regulated so you can up/down the volume.

Why aren't you using a sound processor? Like a common home theater receiver, those will accept your A/V input and convert that to a speaker wires. Unless you got one of those funny speak that takes A/V sockets like BOSE speakers. If that's the case you need to stop by radio shack and get the RCA socket and soldier the stuff yourself.

I've done this for my BOSE cube speaker running out of a pioneer receiver and not the BOSE stock receiver.

Answer 3

The machine you require is called a Audio Amplifier, Line Level RCA input to Powered speaker terminals.
Heres every concievable type of A.AMP available:

Answer 4

You would have to rip apart your dvd player and re-wire it. And more than likely this is not something you can do yourself. Most portable dvd players have a switch to make it an in or out. If you need to have an in, I would just buy another player that has the input. You won't be a ble to convert it yourself. It has to be built that way.

Answer 5

solder it up yourself?
