Two simple questions for Denon AVR owners.
1. After running the auto set-up routine, should the AVR be calibrated to output 81dB or 85dB at the MLP with a reference signal?
2. If manually calibrating the channel levels with an SPL meter, will adjusting them to output the internal test tones at the advised 75dB at the MLP (MV=0dB) achieve the same thing, or will it set the 0dB volume level to 85dB? If it's still 81dB, then presumably setting the test tones to output 79dB (MV=0dB) is required to achieve 85dB at 0dB volume.
I ask because I always thought 0dB would be equate to the conventional cinema 85dB reference level but I just found this on Denon's website which suggests it will be 81dB.
Receiver Volume
Thinking 81dB might simply be a typo error on Denon's part I Googled the subject and found this old thread created by @DodgeTheViper way back in 2009 where he found his AVR did calibrate the channels to around 81dB.
Audyssey Auto EQ & Db levels !
A 4dB difference may not seem much but listening at 4dB lower SPL levels should use less than half the amplifier power so it is a fundamental factor to be considered when specifying a system's power requirements.
