It reduces loading of a high impedance source. What exactly do you want to do? ••• More options Share B bentsnake Member Joined 2014 2014-08-21 12:58 am #3 2014-08-21 12:58 am #3 Take a look at post #2 here: http://www.diyaudio.com/forums/chip-amps/260834-lower-gain-higher-input-impedance-gainclone.html ••• More options Share S sreten R.I.P.

They are also needed for long cables. rgds, sreten. ••• More options Share Show hidden low quality content Status This old topic is closed.
