The audio coming directly from the green (speaker) plug on a desktop computer is too low to directly power external speakers. I bought a pair of "powered" computer speakers and they worked well for several years, although they did not have the best sound quality. I then connected the computer to an actual stereo receiver and got great sound (playing MP3s and videos, etc).
The problem was that the audio from a computer varies greatly in volume level. Some MP3's are very quiet, while others blow my ear drums, not to mention speaker damage. And websites that have audio embedded are nerve shattering.
On top of that, I decided to put the computer back in my bedroom, where it's more handy. There is no room for a large stereo in the bedroom, so I went back to those powered speakers. A few weeks ago, those powered speakers quit working. I opened them and the bare speakers still work, but the built in amplifier is dead, and I'm not even going to bother to try to repair it (probably could not get parts anyhow).
Rather than buy another pair of powered speakers, I'd rather buy a small amplifier and use some small (non-amplified) speakers which I already have. So, I went to Ebay to look for a small amp. I dont want anything that's high powered or I'll blow the speakers or my ears again. I also dont want anything expensive.
I found this one:
There are others, but this one has a power supply (wall module) included. And is in my price range. Not to mention 20W is a reasonable amount of wattage.
My question is whether this will work from the speaker plug on the computer??? (Yea, I need and have the adaptors to convert from the stereo mini-plug on the computer to the RCA plugs). My concern is whether the audio level from the computer will overload the input on this amp, or one like it?
Thanks for all help!
