I have an audio DSP filter for my amateur radio equipment. It uses an LM380 op-amp in the final AF amp stage, using a 100K ohm pot as the volume contr ol. When using a speaker the volume control is fine, but when using headpho nes, the sensitivity from quiet to really loud is only a small tweak of the volume know.
Anything I can do to reduce this sensitivity for my headphone output?
