'fuzzy' is a common sound description when clipping is produced, and other wave form distortion. if you do have a 'line input' use it. also, cut back on gain level of mixers master gain control. 1/2 to 1/4 of normal setting is a good place to start. in a 'normal' operation, mixer inputs and driver amps are preset to a level and mixer *master* is used to control over all level with some slight input level adjusting. in feeding to computer, use level control of software for sound chip to do your level control after you have mixer's channel inputs set. if you have dual line outputs and you want to feed both computer recording and driver amps for monitoring, set mixer master to a low level and adjust level controls on amps to desired. this can be a problem, as it may require frequent adjusting of driver amps. this can be worked around by using a 'bridging' preamp connected to output of mixer to split signal to driver amps and computer and all be controlled from one place. i worked up a simple layout of how this would work using 'xcircuit' and put a snapshot on imagebin, circuit is; http://imagebin.org/69042 for next 7 days. there is another way of doing this using a resistive divider network in line out of mixer between input for amps and computer audio input. it would require a variable attenuator for amp line. if you want, i can work you up a circuit, with values for divider, but i recommend using a commercial made balanced bridged-t attenuator. hth. -- peace out. tc,hago. g . **** in a free world without fences, who needs gates. ** help microsoft stamp out piracy - give linux to a friend today. ** to mess up a linux box, you need to work at it. to mess up an ms windows box, you just need to *look* at it. ** learn linux: 'Rute User's Tutorial and Exposition' http://rute.2038bug.com/index.html 'The Linux Documentation Project' http://www.tldp.org/ 'LDP HOWTO-index' http://www.tldp.org/HOWTO/HOWTO-INDEX/index.html 'HowtoForge' http://howtoforge.com/ ****
