Note: PCB files were not upated! Changes/ required manual rework: - Replace C314 with 100nF to reduce muting fade time - Replace C301 with 680pF to have a 12 kHz low-pass filter on headphones - Replace R309, R232, R335 to fix VU meter range (steps are a bit wonky afterwards, but top (and bottom) range are a lot more save now) - Add 220pF in parallel to R602 to have a 10 kHz low-pass on microphone input More rework is optional: - Replace RV201 with a 10k (fixed) resistor (adjustment is not necessary) - Replace R303 with 1k to reduce gain range from 45 to 34dB
