PCS-Electronics

I bought the card from you guys about 4 years ago. Never could get it to sound real good due to noise from the computer I had it installed in.
Put it in a box for quite a while and dug it out recently....to give it a 2nd try on a different machine. I've found I have to have the sound level set ...

I appreciate the advice, but how do expand or compress
the vco coil?

I have an older PC Max II card. It seems to work pretty well, but I am getting a rumble at times. I've already lowered the bass on the EQ way down. Any suggestions would be appreciated. Thank you.
