and Discrete adding nothing as the input signal is already at 0db; relative to the other channels.
Except that with a movie track the LFE level is always (analog and digital domain) set to -10db relative to the other channels. And all pre-amplifiers will add automaticaly 10db to the LFE level in the digital domain.
May I ask, in detail, how these test where performed and measured?
I have put my DEQ2496 with a ECM8000 mic behind the seats at ears level.
I have made a loop on the DVD of Avatar, when the tree is falling.
On my two BSS 366, i have muted all the channels except the sub channel.
And i have measured the peak level with each preset.
So this test can be done with any disk. And even with a disk with a wrong lfe level, it will show the analog LFE level difference compared to the digital domain
