I have calibrated and tweeked my system using the internal test tones of my preamp several times over the past 2 years. I have checked this at reference with avia and video essentials and all speakers except sub are pretty much at reference.
Equipment
B&K Ref30 Preamp
B&K Ref 7250 - Center, and surrounds
B&K Ref 2220 - Mains
Sony 9000ES DVD Player
Mirage OM5's - R&L Fronts
Mirage OMC2 - Center
4 Mirage OMR2's - Surrounds
Rel Storm III - Sub w/nutrik connection
The set up:
All speakers are callibrated to reference of 75dB using the internal test tones of my preamp. The sub is callibrated to an average of 72dB (needle bounces between 71 - 72.5Db) taking into account the Rat Schak adjustment of 2-3 dB for low frequencies. My Mains are set to large so as to utilize the nutrik connection to support them at their natural rolloff point. The sub is also connected to the preamp through the sub out to handle all LFE. All surrounds are set to small (hz of OMR2's is 80-20khz)
The question:
When I go into the Optimode area of some of the newer DVD's and play there test tones I find all speakers equal and the sub barly audible. It is below 50 dB because it will not even register on my meter. I have checked this with Video Essentials (cannot use avia for my set up because of the nutrik connection to my mains and my mains having to be set to large) and found that the dB level of my sub mathes my other speakers (-2db for meter correction level). Why is this the case? Does anyone know the actual Hz level of the test tones for VE and for the test tone used by B&K's Ref 30 Preamp? Any ideas on this?
