AC Outputs and the AC Input could be used as additional stereo inputs. The input
impedance of the AC Inputs is always 50KΩ.
Speaker Attenuator
The speaker attenuators have exactely the same structure and range like the volume stage.

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.
