Mono signal split

Hey,

Basically I have to split a mono signal, as the topic implies, but without loosing much of the quality. Someone decided to route only the R and no L channel cable from one device to another. The cables are pretty much impossible to access for routing at this point. What needs to be done is R channel cable split into two and sent to mixer's R and L (fake stereo). The mixer doesn't have a mono switch to accomplish this task either. I suppose some small box would do the trick, so I'm looking for a schematic. Can anyone help me out with this stuff? :)

The two mixer channels will be indentical in terms of load, so just attach a second plug to the one that currently goes into the mixer using a short length of cable (tip to tip, sleeve to sleeve).

That simple, huh? Well, that would save me some trouble. Won't the act of splitting the original signal into two paths degrade it a certain amount? Not sure how the physics work out in this situation.

To answer that question with any accuracy really requires more info about the impedance at either end.  Generally, though, you can usually split the output of a line level device to at few line level inputs without any noticeable loss.  If it's a passive, unbuffered guitar at the other end, one line input is too big a load on its own, and splitting to a second will just make it worse.

It's described as an inter-device connection in the first post - no mention of a guitar. The Y-cable solution can be made in minutes; if it sounds rubbish for whatever reason then build a buffer with two outputs.

Indeed - no guitar or any such instrument is involved in this. The connection is between two devices. A video encoder device, that also handles sound, and an audio mixer. I'm going to attempt the split cable approach first, as you suggest, which is an easy and quick test.
