Not to beat a dead horse, but here is a link to my old guru at the, now defunct Tascam BBS, regarding soundcard outputs:

Most PCs supply SPEAKER level power, not LINE level. You are best off with attenuaters, but you might get by by reducing volume to a minimum and bringing it up very slowly.
It was not clear from the original post whether the system in question was to be used for a live performance or for recording monitors. If for monitors, you need far less power handling capability for both amp and speaker.
What needs to be matched is output impedance of amp to speaker impedance, Amps may have different connections for various output impedances (4. 8. 16 ohms). The speaker should also be capable of handling the power (watts) of the amp. It is unlikely you will ever operate most amps or speakers...
While I have used a mini-synth and special electronic circuits to produce the kinds of sounds you are looking for, I prefer to create sounds the old fashioned way. I suggest you experiment with your equipment to determine what you can do with it. You can also find many sites with a google...
Electromagnet= Use a bulk tape eraser with a piece if steel separated from the degauser by a paper thin tab of foam. Record as steady sound and use pan contols to make it move. Add reverb to make "big"
Slide a househod iron across a cookie sheet. Add reverb.
Unless object is moving at a...
Use your stereo adapter and try feeding audio into just one and then just the other RCA jack. If, in either case, you get sound out of both speakers, you have a mono sound card.
Switching the wand On close to the heads is not as serious as switching it OFF too close to the heads (or other parts of the tape path). The wand works by supplying an alternating magnetic field that aligns the magnetinc domains in the material being demagged. first with one polarity, then with...
There are three problems with cold storage. The first is that some electronic components change value. The second is that the lubricants thicken up. The third is that, when brought in from the cold, moisture condenses on metal parts. All of these can be overcome by allowing the machine to...
Am I missing something?
Certainly, degaussing with the power on will overpower the electronics, but how does it magnetize any part of the tape path? Done as described, it can only DEmagnetize these parts.
If they occur in different places. the missing audio speck on one is filled in by the other. This is such a small improvement that it probably cannot even be measured, but theoretically, it IS an improvement.
