Just got the Servo-15 hooked up to my system. Followed the instructions to set the sub volume to mid way and then used the volume control on the x-30 control unit to calibrate the system. It also ended up about mid way.. But when I tried some movies, I felt bass was way too soft. I moved the volume on the servo 15 itself (not the control unit) to close to max and it sounded much better. Did I set it up wrong? Should I set the sub to max volume and then calibrate by making adjustments to the control unit? How do you have your systems set?
