2.9 AC-coupling
In some applications additional signal manipulations are desired. For this purpose an AC-coupling is placed be-
fore the speaker-attenuators, which can be activated or internally shorted by IC-Bus. In short condition the in-
put-signal of the speaker-attenuator is available at the AC-outputs. The input-impedance of this AC-inputs is
50k
. In addition there are MixIn inputs available. With this inputs it is possible to mix an external signal to every
speaker with a mixing ratio of 50% (see Figure 15).
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 ACIn pins
– external ac coupling using MixIn pins
– mixing of ACIn and MixIn pins (mixing ratio: 50%)
If the MixIn pins of the rear speaker are not used this inputs can be used as mixing inputs for the internal sub-
woofer filter.

2.10 Speaker-Attenuator stage
Each of the four speakers and the subwoofer output has a separate volume control in the range: +15... -79dB
plus mute with a typical value of -90dB.
2.11 Output Mixer
A Mixing-stage is placed after each speaker gain/attenuator stage and can be set independently to mixing-
mode.
Having a full volume control for the Mix-signal in the range:+15... -79dB plus mute with a typical value of -90dB,
the stage offers a wide flexibility to adapt the mixing levels.
