10 kΩ ??
10 kΩ ??
I just received my first piece of equipment in the mail today.. It's a RDL audio combiner bought on ebay to convert to mono. It's the same style thing I bought last time, but when I went to the RDL website I noticed that there are differences in models available in 10 kΩ, 150 Ω, 600 Ω

The one I bought off of ebay is a 10 kΩ.. I don't know what that means, I know its 10ohms, but don't know how it's supposed to apply to using the pc as the audio source - Is the one I bought correct for my purpose?
I would suggest this box from RDL for the task you mention:

Because it is a solid state" transformerless" DA you can use it for a lot of different tasks. The unit you bought will work just as well but won't necessarily have the utility of the one unit above.
Hmmmm.. if it'll work just as well, I'll use what I got, don't suppose I need different task, --not as of now anyway.
Just want a mono feed out.
But whats it mean to have the 10 ohms mine has?
Let's say I went to buy my RDL Combiner from their site.. Which model would of I had been correct to choose; the 10 kΩ, 150 Ω, or the 600 Ω
?
For whatever reason 150 sounds right.
RichPowers:
Here's what I would believe about the 3 choices -
10k (which is 10,000 ohms high impedance) - for all consumer line level stereo audio sources, and after conversion to mono the output will plug into a high-impedance consumer level input;
150-ohm is almost always the American impedance for balanced microphones (Europe 200-ohms). But a microphone is already mono, so you probably won'e need this;
600-ohms WAS, in the good old days, the official impedance of all professional balanced audio lines, but not so much anymore. You might only need this version for older pro equipment.
