how come i only hear mono out and not stereo out?

*for MPC 60 II, 3.10 OS, max memory, floppy drive*

i have my stereo outs going to a y-cable adapter > stereo audio adapter > RCA left & right > aux in on my receiver.

i can only hear out of the left speaker.

when i switch the wiring to record into my computer with acid (stereo outs on MPC directly to sound card in on PC) i hear sound from both speakers.

can anyone tell me where i'm going wrong when setting up the house speakers to play from a receiver?

i have a vestax 06 that i use to record samples with. do i use the second line out to send to aux in on the receiver? and plug stereo out on MPC into a free line in on the mixer?

i think i may have tried this before but i could only hear sounds played on the mixer (i.e., playing/scratching a record), nothing from the MPC program/sequence would come thru the speakers. i can't remember if i heard this in stereo or mono, though.

thanks for the knowledge.

Sounds like the cables are messing up. Give us details on what kind of adaptors and cables you are using, there are many different y cables and rca adaptors.

elmac, the cables are:

two 1/8" stereo plugs to 1/8" stereo jack
>
audio adapter (accepts left and right phono plugs, fits 1/8" stereo phone jack)
>
RCA to aux in on A/V receiver

i asked dude at radio shack for a SINGLE wire assemble with two 1/4" stereo out converted to two RCA on the other end, but all he recommended was this setup. he said he hadn't heard of such a cable.

but elmac, when i connect this setup to my sound card input on PC i can hear sound from both computer speakers.

hope this info helps. thanks.

here is a sketch of the setup:

Prime suspect, the y adaptor and cable. One of them is a mono one. your y cable, what kind of plug is on the end? two black lines or one?

If it's one, then your y adaptor is stereo, and is only getting one signal from the y cable cuz it is expecting a two black line plug. If it is two then your y adaptor is mono and is shorting the other signal to ground or leaving it unconnected.

Best solution, just get two single RCA to 1/4 inch plug adaptors and run the two cables to the receiver.

Either that or your receiver's inputs are busted, but you probably checked that.

I love the little block drawing you did of the 60! really cool.

two black lines on "Y" male ends, accepting a male 1/8" with two black lines to RCA.

wait, i thought one black line meant mono (hence "mono") and two black lines meant stereo?

dude at RS said he'd never heard or seen such a cable. where might i find a cable like the one you described? maybe try another RS?

i'm stoned and figured a little diagram might help. i love me some MS paint. BTW, check out these MS paint drawings a few folks at this other message board i visit posted up:

i never had the patience to finish one. some of those dudes got mad attention spans/dexterity to paint with a friggin' mouse!

Ah, that's the problem, the outputs on the 60 are mono, using both for stereo like you are, when you inster the stereo plugs into the 60, it essentially turns them into mono jacks, only sending signal to the tip, the ring is shorted to ground. So the end of the stereo y cable is now mono.

You need an insert cable, one that has a pair or mono jacks and one stereo plug at the end, that way one mono signal will go to tip and the other will go to ring. If your y adaptor is also stereo, this will work.

it's not a cable you need, but an adaptor that takes an RCA plug and has a big jack at the other end (mono).

Or a y cable that has one mono and two stereo plugs.

Either way should be fine if your adaptor is stereo all three ways.

RS has them in little packets, the people that work there often don't know what they are talking about, talk to a manager rather than the floor staff if you want some decent info, but don't trust them either.

thanks for help, elmac, but i'm still stumped.

can you try drawing a diagram?

Nah man, wait til it wears off and read it again, it might sink in there.

What you need is two of these:

http://www.radioshack.com/product.asp?catalog%5Fname=CTLG&product%5Fid=274-884

plug those into the mpc outputs, then connect the rca cables from them to your receiver.

That takes the y adaptor out of the mix, and will work for sure if your receiver does.

But the main cause of your problem is you have a y cable with all stereo ends, you need what's called an insert cable in that set up, two mono ends (for MPC outs) and one stereo end (for the y adaptor) but it's better to just get two of the ones in the link above and remove the y adaptor altogether.

Those are more versatile.

So jot down the part number from the link, head down to RS, get two, and make sure your RCA cables will reach from the mpc to the receiver, or get longer RCA cables and you'll be set.

You don't need to get the gold ones, the nickle ones will work too.

And that Y cable, what it is used for is combining or splitting a stereo output jack, so you have headphone out on your mixer or something, plug one in there, and you'll have two jacks to put into two different places, or take headphone out of two stereos, and plug the other one into a recorder that takes a stereo plug.

Ok, that was probably more confusing, but you know what to do now.

nice. i think i got it now, 'mac.

thanks again man.

No sweat, I love audio riddles.

i really don't think i will ever need these parts again and it's too late to return
'em. my $10 could've gone towards more rekkids!!! ohwell.
