My new Oppo player has direct analog output at 5.1 can I just plug the sub out put into the sub? For that test?
Yes, you can do that, and it is a really good test as it eliminates all other variables. But start with the volume knob on the EP500 all the way down. Bring it up gradually. Running a full line level, like the outputs on the back of a player, is the same as having volume turned all the way up (-0 dB) on a receiver.
The Oppo does have it's own volume control too. Make sure it is at 100%.
EDIT: Now that I think about it, just hook the Left of the stereo out of the Oppo to the sub. That way you won't have to full with the cross over settings in the player. You should just be able play a CD, and hear the bass portion of the music coming from the sub.
