Fig.1 Damaged path of the MUSES72320 The input coupling capacitors(CIN) and the input resistance(RIN=20k) form a high-pass filter with the corner frequency determined in [fc=1/(2RINCIN)]. The Rbias affects the Volume(Att.) linearity characteristic. When Rbias value is too small, the amount of attenuation increases, so that the output amplitude becomes small and THD deteriorates by an internal analog switch. On the other hand, when Rbias is too large, it may be affected at the noise from the outside. Please decide resistance value after it verifies it enough by an actual application.
