Can someone explain to me some of these settings? I have a pioneer elite.
I really don't understand #7 and #9
Terminology may vary from model to model, however I'll use the terms that apply to my Pioneer 1015, which shares many characteristics with the Elite series, but not all.
6. His wording is not clear to me either, so I'll try a different approach. The Subwoofer channel (MCACC menu) must be set to "Yes," activating it. In the "Other Settings" menu, there is an LFE ATT submenu. If this is set to "LFE OFF," you'll get no sound from the LFE channel. (See 7.)
7. You should set LFE ATT to "0," which means no attenuation. This is the default.
8. My receiver does not have the option of changing THX bass parameters, so this would not apply. The only bass limiter I have is the LFE ATT mentioned above. If you have a THX submenu, you can check, but no doubt the default would be to disable any bass limiter.
9. -5 is a commonly recommended, but arbitrary starting point. The idea is to have some room for upward adjustment when you calibrate. It's best if your final calibrated pre-amp setting is 0 or less, but +1 or 2 won't do any harm. Use the subwoofer amp's volume control for the initial rough adjustment, so that the sub will approximately balance with the other speakers at -5 before running the MCACC. Most people boost the subwoofer pre-amp out setting again as a last step in their calibration process, winding up with their subs running 3-5dB hot.
