There are many USB and Firewire audio interfaces, that have no circuitry to protect your speakers from the power surge when the computer gets turned on or off, to pass through the audio I/O system and on to your speakers, creating loud pops that can blow the tweeters of expensive monitors.
Matter of fact, the audio interfaces that have such protection seem to be in the minority. Because of this, I'm too scared to use my monitors with my newly set up recording system.
Since turning on the stereo never makes your spakers pop, and there's also a pretty cheap Logitech USB audio interface+speakers combo that never does pop on cycling the computer's power switch, I know there must be some way to prevent this by adding the right kind of circuitry.
While I'm not bad at soldering together circuits, I just can't figure out where I could intercept this.
Would be nice if it was something you could just build into the speaker cable, but if I have to open up the device, that's fine too...
Trying to logically figure out where the pop originates, I already fail. The audio device takes a digital audio stream from the computer's USB port. I doubt if the pop comes from there, it seems unlikely that the computer would create a pop and convert it to a digital stream to pass to the audio device...
So it seems more like the USB device's power supply must be lacking some form of protection? But then, the computer isn't very inductive like a fan or refrigerator, so it shouldn't really be sending a surge through the whole power circuit in the house??
If anybody has an idea where to attack this problem, I'd much appreciate it :)
