I'm not an audio guy, but my job has me recording and editing. We are using Audition 2 and recently purchased TASCAM FW-1082 boards. The only useful thing on the board seems to be the gain knob. The sliders don't adjust anything while recording. Also, the gain knob is only useful during the last 1/4 of it's rotation. Anything less than that, and the sound doesn't record. Any help would be great. Thanks!
