AC coupling
In some applications additional signal manipulations are desired, such as additional band
equalizations. For this purpose, an AC coupling can be placed before the loudness
attenuator or speaker-attenuators, which can be activated or internally shorted by I2C bus.
In short condition, the input-signal of the speaker-attenuator is available at the AC outputs.
The input-impedance of this AC inputs is 50 k
Ω.
