Switchable volume reduction. In situations when I need really low volume I added SPDT switch which reduces volume for 7dB when activated. Using my L-Pad calculator I got values for series and parallel resistors: Rs=2.2ohm, Rp=3.3ohm. I choosed that attenuation level because 2.2ohm and 3.3...
Using my L-Pad calculator I got values for series and parallel resistors: Rs=2.2ohm, Rp=3.3ohm. I choosed that attenuation level because 2.2ohm and 3.3ohm resistors are easy to find. Also, I added treble bypass cap which restores some treble lost by attenuator. It’s a 4uF non-...
