I need a volume control for my bi-amped system. I had the crazy idea last night of how to build a cheap stepped attenuator of reasonable quality. The typical volume control has a 24 position switch and attenuation steps are 2dB for most of the range with a few larger steps at greatest attenuation, Max attenuation is about 48 to 60dB
I thought of using two 8 position switches instead of a single 24 (or more!) position switch.
The first switch is wired in 8dB steps, the second in 1dB steps giving 64dB of volume control in 1dB steps, Think of it as coarse and fine adjustment.
Now you know what I'm thinking, here comes the question:
Are 1dB steps way too small? This could be significantly cheaper with 6 position switches (2dB and 12dB).
