It's always running - it's a voltage multiplier that generates 55VDC and 11VAC for the display. We pull off approx 12-13VDC at one stage in the multiplier, filter it, and then regulate it down to 9V and 5V. Power is actually slightly quieter at _higher_ brightness levels because the regulator drop-out margin is increased. -- seanadams ------------------------------------------------------------------------ seanadams's Profile: http://forums.slimdevices.com/member.php?userid=3 View this thread: http://forums.slimdevices.com/showthread.php?t=20155 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
