nice to meet you
. I have a very similar problem, yet none of the solutions worked for me. Here's the deal:
Yamaha rx-v675 receiver
Dali Zensor 1 fronts
Dali Zensor center
BK XLS-200 subwoofer
I set sub cross-over at max, low gain mid-way, LFE filter out to let receiver drive the bass (as per manual), phase to 0. Ran YPAO, it found the speakers large, found the subwoofer, set cross-over to 40 Hz, level to 0db for all, distances correct. Subwoofer volume was barely audible. I changed speakers to small, cross-over at 80hz. No change. Moved it a bit in the room back and forth - no change.
Ran test tones - speakers audible, sub barely a very discreet rumble.
Turned level up to +10db, the sub became audible, but not sure it's "healthy", and not sure it's a correct sound (have no experience with this stuff). Shouldn't it work with the level at 0db?
Did a factory reset, ran another YPAO, same results as before. Then ran another YPAO with sub gain know down around a quarter, it set the sub at +10db and speakers at -6.5db. Odd.
Tried different sources, net radio, HDTV via HDMI, PS3 movie, no big difference. Tried pure direct (although i know that has no sub, just to see the difference), tried 7.1, tried all PEQ options, all pre-set sound options - nothing. I even switched the power cable in the socket 180 degrees as I saw on one thread. Nothing. Connections as in the image below. Light on the back of the sub is red - does that have to be green?
Tried Sub 2 from the receiver, tried Left connection on the sub, to no avail.
To see if the sub works with another source I hooked it to a media player, white audio out - my ears hurt from the sound, 'cause i forgot to turn the volume down - it works, very loud.
There MUST be something in the receiver settings, I refuse to believe the receiver is faulty - 3 months old, bought new. But I have no more ideas, and Tom from BK doesn't either - he's been very helpful but we couldn't crack it. The sub needs only 0.01V to be driven, Yamahas are supposed to give 0.7V. Sub doesn't have "auto on" as far as I can tell.
What to do? I haven't come to terms with leaving the sub at +10db, even so it is not too loud. I'll do a sub crawl but placement can't be the issue, I don't hear much of an improvement regardless where I stand in the room.
Room is rectangular, closed, speakers by the short wall, subwoofer at the right, long wall around the middle, close to the receiver (don't have a long enough cable just yet to move it to the corner). Listening position against the glass window and door - i know it's not an ideal arrangement, but it will have to do. Approximate layout here:
Has any of you had a similar combination sorted out?
Thank you so much in advance for any ideas!
