it's interesting how the 950 handles dolby 1 (all speakers 'small'). this is from crystal:

"In cases such as Dolby Configuration 1, a gain (e.g.+10 dB) is not directly applied to the LFE channel to drive the subwoofer. Instead, the inputs to summer 802 are attenuated to acheive the same result. In this example, the L,C,R,Ls, and Rs channels are all attenuated by -15 dB and the LFE channel is attenuated by -5 dB. This implements the LFE +10 dB channel specified for Dolby Configuration 1. However, a compensating 15 dB gain should be applied later, usually in analog, after the DACs."

i'm still thinkin' about this one...
