Truncation of LSBs would be a perfectly fine way to express it. For safety you want to be sure that an accidental reversion to 100% digital volume will not damage your speakers. A passive TVC (transformer volume control) might be worth considering, depending on your definition of minimalist. A resistive divider can be good if you need a lot of attenuation, because you can then get a good ratio of input impedance to output impedance. You would like your passive volume control to be easy to drive from the Squeezebox side, but still have low enough source impedance to drive the power amplifier without impairing the frequency response. Much depends on the input impedance and sensitivity of your power amplifiers. -- dsdreamer ---------------------- "Dreamer, easy in the chair that really fits you..." ------------------------------------------------------------------------ dsdreamer's Profile: http://forums.slimdevices.com/member.php?userid=12588 View this thread: http://forums.slimdevices.com/showthread.php?t=66479 _______________________________________________ discuss mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/discuss
