I have a Sound Blaster Audigy Player, don't really wanna upgrade it for the time being, and it doesn't have a digital in, so I'm using the phone jacks. I've just bought myself 2 mono 1/4" jacks and a 3.5mm stereo jack (and some wire). I'm gonna be wiring it up at work today, and don't really have a problem doing it - but I AM worried about plugging it into my sound card. It's got a line-in, which is what I plan to plug it in to... but I'm worried it might damage the sound card / speakers. I don't understand impedance - all I know is that my amp itself has 2 speaker outputs with a 4ohms impedance. Could the output signal from the GT-6B's right and left channels (phone jacks) blow my sound card? Do I need anything in between?
