[Charles] “When you have two different sources of “amplified” signal, I believe you better use an A/B speaker switch. You don’t want to feed an amplified signal to an input source in a second amp. But, if I’m wrong, I’m sure someone will correct me.”
I agree.

[Ron Shook] “I don’t think that mini-plugs are ever balanced. The stereo ones are simply 2 channel unbalanced. While you will run into 1/4″ tip/ring/sleeve connections that are either stereo unbalanced or mono balanced, I’ve never run into a balanced 1/8″ mini-plug connection. I suppose it’s possible, but I’ve never encountered it.”
Ron,
For the most part you are correct.
However if you build your own cables or use the wrong adapters you can create anything. I’ve seen it done lots.Regards, Rick.

[Charles] “The audio connections from your sound card to your amp or speakers should most likely be: 1 mini-RCA plug for the front, 1 mini-RCA plug for the rear”
Just for the record, there is no such thing as a mini-RCA
plug. There are RCA plugs and their are 1/8th mini plugs.
The mini-plugs can be either mono (unbalanced) or stereo (balanced). Be careful, you don’t want to plug a stereo mini into an unblanced mono input.You can use adapters as needed to interface your soundcard outputs to your amp inputs or power speaker inputs.

[george12] “I have a wav file and I would like to transpose it 5.1 surround sound. How to do it?”
A stereo wav file will always be a stereo file. You could fade it into the rear speakers however it would still be a stereo source faded into the rear speakers (no space). You could perhaps add some reverb or delay to the stereo track and fade that to the rear for more space. However it still would not have the depth and space of a true 5.1 mix.
You ask how do I get a 5.1 mix? You take all of your elements (tracks) and put them in different locations in the surround landscape, or use a surround mic to capture your soundfield.
Regards, Rick.

[Ron Shook] “am I correct in believing that I can encode to 5.1 Dolby in Vegas without resorting to 3rd party software?”
That is correct.
[Ron Shook] “If I do so, does 5.1 work OK in a stereo playback system or is there some distinct advantage to having a separate stereo file.”
The playback device will downmix your 5.1 to stereo mix. As long as you do a decent 5.1 mix it should downmix well.
Vegas has a downmix button that allows you to listen to your 5.1 mix downmixed to your stero speakers. Work much the same as a stereo to mono switch.[Ron Shook] “How do you get the 6 channels out of your editing system discretely and fed to your speakers.”
A multichannel soundcard with discrete outputs feeding either
powered speakers or poweramps.Regards, Rick.

[Bernard] “I video taped a band last night. I ajusted my camera audio input, but the audio was still distorted. How can i fix it. Is there a pro audio software which can repair the clipping?”
If the audio was distorted at the camera when you taped it
there is no way to remove it. The software that was mentioned by previous poster will help you if your record level was a bit to high. If you pluged a line level board feed into your mic input your out of luck. To record directly out of a board into your camera’s mic input you need a “Line Level to Mic Level adapter”. If you recorded them using your camera mic and
it is distorting because the level got to high, software can help you.Regards, Rick.

[mp_audiovisual] “eventually a certain frequency will sound like it’s doubling up, this is the subharmonic frequency from the ambiant room noise,”
Your technique sounds ok however the correct terminolgy
here would be “Harmonic”. Sub harmonic is a frequency below the fundamental. You most likely will have room tone reflections both above and below the fundamental frequency. Therefore using the term harmonic is a more accurate statement.Really what you are trying to do here is drop the frequencies that the room is resonate to. This will vary room to room.
The technique that you described helps you quickly identify those frequncies. They will, as you described jump out at you once you get on the resonate frequncy. It should also be noted that once you locate the resonate frequncy you should tighten (narrow) the Q (how much you affect around your center freq.) If you set it to wide you will put a big hole in your audio. You want to use as tight of a notch as possible while still addressing the resonate frequncies.Regards, Rick.
