AC-coupling
In some applications additional signal manipulations are desired. For this purpose an AC-
coupling is placed before the 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 50k
Ω
. In addition there are Mix
In
inputs available. With this inputs it is possible to mix an external signal to every speaker with
a mixing ratio of 50% (see
Figure 17
).
The source of front and rear speaker can be set independently. As source is possible to
choose:
–
internal dc coupling (not recommended)
–
external ac coupling using AC
In
pins
–
external ac coupling using Mix
In
pins
–
mixing of AC
In
and Mix
In
pins (mixing ratio: 50%)
If the Mix
In
pins of the rear speaker are not used this inputs can be used as mixing inputs for
the internal subwoofer filter.
