Hi Steven,
Here's a guide to setting up the correct subwoofer level on your receiver setup menu and on the EP-175.
Set the EP-175's level control to about the 11:00 a.m position.
On the receiver's sub output setup, adjust the level so it's at the "0-dB" setting. Leave it there.
From now on, use the EP-175's volume control to trim the overall subwoofer level. It the EP-175 still doesn't come out of its "sleep" mode to "On", nudge up the sub level on the receiver setup menu by +2 or +3 dB. If the sub still doesn't turn on, call Joe Vassallo on our toll-free line and he'll take it from there.
Ideally, the receiver sub level should be left at 0 dB, which should provide enough voltage to activate the auto-on circuit in the sub.
Regards,
