Is there any schematics on how to convert, by rewiring, the audio
output(headphone jack) in an average cd/radio/cassett player to audio
input for distribution through the speakers?

If anyone could help me out on this or give direct me to relative
information, I would greatly appreciate it.

It's not easily possible and you'd have to know a lot about electronics to do
it.

Forget it.

I agree. Not to put it too crudely, the fact that you are asking the
question means that you would not have the technical knowledge to do
this. There are just too many variables to be be able to give you
generic advice as to how to do this. There's no such thing as an
"average" CD/Radio/Cassette player, there's just too much difference
between various types. If you have a proper service manual (not user
manual) for the one you want to convert, with a circuit diagram, then I
and others here may be able to advise you on how to do it. If you want a
cheap PA system, there are a number of Karaoke systems on Ebay which
will do the job.

Yes, first find a tiny little circuit part called a "power amplifier", and
wire the "power amplifier" so that the signal that used to go directly go to
the headphone jack, goes to the "power amplifier" first. ;-)

Is there a problem using a powered speakers like something you might use on
a PC. Then all you would have to do is plug them in.

If you are asking how to convert a CD player so that it will
record, then the answer is simply no.

If anyone could help me out on this or give direct me to relative
information, I would greatly appreciate it.

No information is available as it is not possible to do.

How do you contrive to read "for distribution through the speakers" as
"for recording"?

What's to interpret? Youre the one who's invented the recording
requirement.

Thanx to some of you ppl for your info. Serge, I don't have a service
manual (although I could probably get one online somewhere), but it
seems you have some knowlage or 'know abouts', so if u could just
direct me to some schematics of a remotely average radio/cd player.
Thanx

What's an " average radio/cd player " ? I think you missed the point somewhat. The
only generic way to exaplin what to do would be a block diagram but you'd need to be
fairly techy to idenfify those bits in your product so as to see what to do.

Sadly, no. As Graham mentioned, you seem to have missed the point that
there's no such thing as an "average" unit. For example, is the volume
control on your unit passing audio through a standard potentiometer, or
is the volume control controlling an electronic attenuator? Do you even
*have* a physical volume control, or is it an up-down electronic device?

You need to know this, as the simplest way of doing what you want is to
put the incoming external audio onto the volume control, perhaps using
switch contacts on the jack to switch between internal and external
audio automatically. However, you need to know firstly if the jack *has*
switch contacts, secondly, what sort of volume control you have and
thirdly, can you physically access these for soldering. Many modern
devices use surface-mount components on a multi-layer board, and what
you need to access is buried in one of the middle layers. All in all, a
lot of trouble, when you can buy something suitable quite cheaply
already done for you.

Best of luck whatever you decide.

Fine. Get a radio, just about any, with an aux input on the rear. Get a
suitable connecting cable, insert the phone plungs in aux input, bend
the cable under the radio (assuming that is has short legs, most devices
have ...) so that the suitable receptacle (sp?) or plug that fits the
mp3 player is accesible at the front, and you're done.

So I guess you don't have more info you can offer?

In very simple language (complicated has been tried by several people
and failed to get the meaning across): you can not make an ass into a
mouth.

Well I guess I am been pushy, but it's frusterating not knowing
exactly how to do this.

Enter Radio Shack or local equivalent, approach clerk, ask for cable to
connect the mp3 player's headphone output to your radio, feel free to
bring both if unsure so that the actual cables usability can be verified
on the spot.


Kind regards

Thanx for your explination. I hope I'm not been pushy, but I really
want to do this because it seem so ligitimate, I mean radios are every
(almost all having audio out-put) yet they're so diverse & complicated
that everyone has to resort to dealing with expensive speakers of no
portablity.

I just want to have a radio that I can plug my mp3 player into and
have it function like a portable speaker system, so it'll be as simple
as a radio yet I'll be able to have digital sound and a playlist of my
own without having to deal with the inconvience(not so big capacity,
length of burning time, also not all radios have mp3 cd readers) of
burning an mp3 cd.

Also It's a thing of pride, I just want to do it. And I have searched
the internet - using all relavent keywords I can think of - but
haven't found any information on how to do it.

So I guess you don't have more info you can offer? Like maybe some
diagram showing where the exiting audio signal is just before going to
the speakers or where the audio signal is just after leaving the sound
processor on the cd drive. I know this diagram will be most likely
quite different than the wiring and circitry on any radio I have, but
you could state what specific radio/cd player this hypothetical
diagram is for.

Well I guess I am been pushy, but it's frusterating not knowing
exactly how to do this.
