A pre-amp doesn't limit signals in the way that you suggest anyway. It simply applies gain or attenuation to the input signal and passes it to the power amp. It may or may not buffer the signal as part of this function.
Other typical pre-amp functions are input selection, balance and mute. Some even have some form of 'tone' controls. -- Patrick Dixon www.at-tunes.co.uk ------------------------------------------------------------------------ Patrick Dixon's Profile: http://forums.slimdevices.com/member.php?userid=90 View this thread: http://forums.slimdevices.com/showthread.php?t=25773 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
