If it sets your sub to close to 0 or above, raise the gain and rerun YPAO until it sets the sub near -6 to -8. After YPAO, raise the subwoofer trim level 3 to 6 dB to taste.
When funds permit, do get a Umik-1 mic and a miniDSP for about $200 total. It will help you transform your in room frequency response from looking like a scary roller coaster to a nice flat line.
So I FINALLY got around to setting everything up this past weekend.
I plugged in the YPAO mic and set it on a tripod, ear level, in the middle of the seating area; near where the coffee table would be. I figured this would give the best overall sound for all guests on any part of the couch. I set the receiver to a volume level of 0.0dB.
I initially set the Rythmik sub to 50% volume (or the dial at 12 o'clock). This brought the sub to +8.5dB!
I re-ran the test two more times and in the end, the sub volume dial is at roughly 75% or (3/4 o'clock). This got me to -6.0dB. I then hooked up the Radioshack SPL and dialed in all the speakers to 73dB, with the center at 75dB. I then increased the subs level to -3.0 on the Yamaha software (leaving the volume dial at 3/4 o'clock). It also set the crossover to 100Hz. With that said, I then matched the physical crossover dial on the sub to 100Hz, instead of 120Hz. Is that correct? Or should I leave the sub dial maxed no matter what?
With those settings, I'm sitting at a listening level of -15dB or so on the receiver, which puts the volume at a proper theater level, IMO.
Does this setup or configuration sound right? I think I'm going to bump the sub up a bit more. Which way should I do so? Increase it through the Yamaha software, or should I increase the physical dial on the sub? In the room, you can hear the bass, but you don't feel it as much as you do when on the floor above!
