When using any DSP mode with true analog inputs (cassette, R-R, phono, tuner, etc.)it is my understanding that those inputs are digitized at 48KHz sampling rate and 24bits PCM.

Obviously the 950 has some sort of AGC (automatic gain control) since other A/D units have had manual input level controls which had to be set by the user. Anyone who has ever tape recorded knows how critical recording levels are for maximum S/N level.

Since my compliment of analog equipment outputs nominal 0 dB levels ranging from 250Mv to 2.0 V (which represents an 18dB voltage level difference). It seems reasonable that some optimum input voltage range would produce the best S/N ratio and best use of the dynamic range available with the 24bit A/D converters?

Does anyone have a clue as to what the true situation is regarding this issue? That is, what analog input levels best 'feeds' the 950's A/D converters for DSP processing of analog inputs?
