Would this work??? HELP

[JakitoMaN]

i'm trying to get 2 - separate channels of audio, and combine them into one without using a mixing console. i drew this schematic, and was wondering if it would work...

if it doesn't then what options do i have?
Thanks in advance!

It'd be easier to give an answer if you'd mentioned what you're trying to combine with that wye. It all depends on what you're trying to "wye" together and what you're "feeding". Two "balanced" analog signals to a "balanced" analog mixer input, say, could do OK. Then again, maybe not. You might end up with a "scrambled" balance, and have the signals out of phase with each other. Signal "top" (drawing reference) influences signal "bottom" and they both try to get to the other's "source", so strange things can come out from signal "left" TRS. In other words, they may not be "equally" mixed. If you're dealing with mis-matched sources (+4 & -10), you stand a chance of blowing the circuitry on the weaker of the two sources. Also, the voltage involved is summed and could blow the input circuitry of "left". It'd be "safer" to use a little mixer of some sort. If you're going into or out of an "insert" ("send/recieve") jack, I would NOT combine at all, because now you're talking about combining & splitting that can get messed up. (The Roman Empire built some mighty nifty roads to use for support of their troops, way back when, but they were also great for the invading army to use, if you catch my drift). If you're dealing with unbalanced signals, and need a cheap and "dirty" mixer, don't forget your old faithfull tape decks. (A balanced signal, of course, would lose it's "balanced" circuitry.) A cassette or rtr recorder usually has line and mic inputs, and could be used to combine 2 signals to one. Don't expect a "clean" signal, tho.

thanks, i kind figured i wouldn't get a clean signal. i just don't want to spend the money for a little mixer. for that i save some money and get a better one. ...

what i'm trying to do is recording ADR for a friend. the problem is, the person can't hear himself and the original audio at the same time . when i get it so he can hear both, it records his voice and the original audio.( i'm using audition if that helps ) so i'm using the input of one sound card, and the output of another. it was a temp. solution but he still couldn't hear himdself, just the original audio. if you can give me some advice that would be great,i've tried everything i can think of, at this point i'll take all the help i can get. i'll be looking for a cheap mixer for the time being.

thanks in advance!!!

Hi
Put 1/4 watt 1K resistors in line on the tip and ring of each send where they sum.

And the 502 wich has 7 inputs for about 35$!
Very decent quality; at least very quiet.

i might try putting a resistor in ,see if it'll work, just for kicks... but i'm going to end up buying a small mixer...but i called a couple of places, and they don't carry behringer, but they probably have some knock off of it... i know i can order over the internet, but i just don't want to... but thanks for your input, it helped me out a lot! you guys rock!!! if theres any other way to get around using a mixer let me know...please!

Search for "Craig Anderton tips",
he used to give schematics on how to achieve
many DIY such as mixing without a mixer.
Still, I don't see why one would bother with soldering iron...35$...!;)
