It doesn´t have to happen but it can happen. Besides in this case it is for the good cause and like volume attenuation it could possibly done at the 24 or 32 bit resolution. As for digital level attenuation, it can be done so there are no hearable loss. However in the context where we use SB and SBS for xover and still keep the main architecture intact, the level attenuation is done in the SB, having, so in 24 bit. That gives a whole 12 dB to work with untl we start to have impact on 16 bit recordings. Since we´re discussing speakers without passive xover, we can also assume the speakers are easy to drive. let´s say 95db/w (simplified since one have more than one "speaker" in reality). Even with moderate amplifiers, let´s say 64 W per amp channel, the listening volume would still be very very loud when you have used up all your window of 12 dB without resolution losses, everything at lower volume lever than that 101 dB will quickly start using bits lower than the bits over 16. So in conlcusion digital volume control when using 24 bit will in reality affect the resolution so it can be heared unless one add extra attenutaion, have very weak amps or speakers that are hard to drive. -- johann ------------------------------------------------------------------------ johann's Profile: http://forums.slimdevices.com/member.php?userid=10177 View this thread: http://forums.slimdevices.com/showthread.php?t=86650
