I've used the Essence line of sound cards for quite a while. A recent motherboard upgrade left me without a slot for my ST so I picked up an STX II. It works, but the output is very low. I'm coming out the RCA jacks into a power amplifier. I have subs hooked up to the daughter card. The mains and subs levels are in balance so it seems like it's not an analog issue. The daughter card is the same one I was using previously. Any help would be greatly appreciated.
