2 Questions Regarding EP500 Settings

Where is your Sub volume on the Sub Amp?

7:00 or less
8:00

Greater than 9:00

Where is your Trim setting?

Full

When I am using my SPL meter to 75 db, My receiver is at -10 w/all other speakers around +6 and the Sub is still registering 5-10 DB above the others on the meter!! AND my sub volume is at 8:00 (less than half)

Thanks for feedback.
