Barry, I believe you have it right, and I'm sure others will jump in and correct any misconceptions. I'm not an ee, but here is what I have come to understand via following Sean's (and other's) posts.:
There are independent volume controls for the digital and the analog output connections. 1. The analog outputs have a 2-stage volume control. One stage is the "preamp volume" attenuation you set in the player settings, and this setting is meant to limit your max output voltage so that you can run direct into a power amp w/o a preamp. This setting is not adjustable from the remote control, and is generally set according to your amp's input voltage requirements and your desired maximum listening level. The units of measurement for this control are in DB of attenuation, but can be converted to actual voltage with some formula that's floating around but I don't have handy atm. (sorry) The other volume control is the standard volume control used from the remote control which operates from zero up to the maximum you have set in the preamp volume. 2. The "digital" volume control affects the output level from the digital outputs. It can be set to "fixed" (at full output) which decouples it from the remote's volume control. By default it not fixed and will vary along with the analog standard volume from zero to 40. 3. If I set the digital volume control to "fixed" I can vary the analog output volume without affecting the digital output level. 4. Preamp volume attenuation does not affect the digital output level. 5. When digital volume is set at 40, or is set to "fixed" - then no resampling takes place. The SB3 digital outputs the source pcm signal unchanged. If you limit the digital volume then the SB3 will resample in order to lower the digital output level. -Dan -- dwc ------------------------------------------------------------------------ dwc's Profile: http://forums.slimdevices.com/member.php?userid=1892 View this thread: http://forums.slimdevices.com/showthread.php?t=21772 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
