People suggest combining signals by using Y-splitter cables so often, I feel this article, posted by Pro Sound Web and authored by Rane, should be a sticky.

Why Not Wye? When Combining Two Signals Into One Is Not A Good Idea (http://www.prosoundweb.com/article/why_not_wye_why_combining_two_signals_into_one_is_ not_a_good_idea/av)

AMP!
That is a fantastic article. An excellent idea to sticky it.
In the distant past, I used y-cables to combine outputs. I never had a problem doing it, but it never really worked as well as I would have liked. Looks like my luck held for a while. Live and learn, I guess.
The best thing about the article is that Rane gives actual solutions to the issue. They don't just say you shouldn't do it, then leave the reader hanging.
+rep if I can ever figure out how to do that
Cheers

That is a copy and paste from the Rane Notes, there's a wealth of good articles there. http://www.rane.com/library.html

Rane Notes are a lifesaver. Had em bookmarked for almost 8 years now. Have told MANY people over the years about the summing networks in Note #109.

Fully credited... but yes, you're exactly right. I just thought that having PSW's endorsement added SOME credibility... not that Rane really needs outside endorsement to make their opinion worth heeding.

I thought that was common sense? But ok. +Rep

I don't like using Y-splitters in general, but they shouldn't hurt too bad when splitting an audio signal.

All you need is a small mixer to combine two sources anyway.

^^ this... plus, having a small format live mixer like the Peavey PV6 or Soundcraft Notepad 102 around is not a bad idea. They come in handy so often.

Here's and inexpensive mic combiner with balance control about the size of a pack of cigarettes.

I see that's a mic combiner. Does it work equally well on line level signals?

For my purposes, these have worked well for me on mix/split duty but because they're Behringer, I hesitate recommending them. Have two. I've only used them for line level applications. Most recently Iused one like a press box so somebody could tap into my mixer's main output for his video of the event I was providing sound for.

It should but I've never tried it.

I used to have a Rane version of that, the Rane MLM82 http://www.rane.com/pdf/old/mlm82man.pdf As for the application you mentioned, I used to either use the booth/monitor out or the record out for when I need to send an audio out from my mixer to the video man.
