AC Outputs and the AC Input could be used as additional stereo inputs. The input
impedance of the AC Inputs is always 50K
Ω.

Note: In general the center frequency, Q and DC-mode can be set
independently. The exception from this rule is the mode (5/xx1111xx)
where the center frequency is set to 150Hz instead of 100Hz.
