Speaker Coupling
In some applications additional signal manipulations are desired, for example surround-sound or more-
band-equalizing. For this purpose an AC-Coupling with four different AC-Coupling inputs is placed before
the speaker-attenuators.
The input-impedance of the AC-Inputs is always 50k
with exception of AC input ACin1, which has pro-
grammable input impedance. For ACin3 exists an internal mixing stage and an internal mono low pass
filter, which is available as input only for the speaker FreeL/R.
There are two possibilities for internal DC Coupling:
– main channel after the bass filter
– main channel after the middle filter (same as at ACout pin)
The I2C bus programming tables shows the possible speaker sources.
