1.13 Speaker-Attenuator and Mixing
A Mixing-stage is placed after each speaker-attenuator and can be set independly to mixing-mode. Having a full
volume for the Mix-signal the stage offers a wide flexibility to adapt the mixing levels.

1.14 Audioprocessor Testing
During the Testmode, which can be activated by setting bit D0 of the stereodecoder testing-byte and the audio-
processor testing byte, several internal signals are available at the FD2R- pin. During this mode the input re-
sistance of 100kOhm is disconnected from the pin. The internal signals available are shown in the Data-byte
specification.
