Balanced mono to unbalanced stereo?

Balanced mono to unbalanced stereo?

Hi, I'm wondering if someone can help me in figuring out some wiring I need to help someone with; I need to go from a balanced mono jack to an unbalanced stereo jack. Basically they need to connect a pair of headphones to a mixer's direct out. It's far from an ideal situation I know but it'll have to work like that for the moment.

Of course it's line level but it seems to drive these headphones sufficiently; the only problem is there's only signal on one side. What would be the best way to wire this up, keeping in mind the direct outs are balanced?

I've done some research but don't seem to find anything on this particular setup, and being far from an expert it's hard to figure this stuff out from the info available.

Thanks!

I'll try not to ask why you seem to think this is a good solution, and see if i can help...


If you a pluggin a TRS into an insert point, you have a send and a return on the jack (most likely T is send, and R is return), which means that you are only sending signal from the insert through the T-pin.

When you plug one end of your cable into the mixers insert point, you only have signal coming through one wire and into one side, because the T and S are seen as left/right unbalanced on your headphone amp. You only get signal on T(tip).

You will never get stereo from this, unless you use two channels and two insert points, but you can send the same signal to both sides of the headphones if you want..

Try connecting Tip from the direct out to Tip and Ring for the headphones, and just connect both sleeves.
That should work


...but also try the Solo AFL/PFL button on the desk using the headphone output

Well I certainly don't, but as I said it's not for me And it's for a specific use which is currently served well with this setup. But certainly a headphone amp at the very least would be preferable.

Just to clarify, this is on a direct out, not an insert, and of course, I'm not looking to get "stereo" but simply get the mono signal sent to both sides...

I figured it might be that simple, but being a balanced signal I wasn't too sure ... looks like that's all there is to it then.

Thanks, will try it out.
