TDA7405
5.10.6Output Selector
The output-selector allows to connect the main- or the second-source to the Front-, Rear-speaker-attenuator,
respectively. As an example of this programming the device is able to connect via software the main-source to
the back (rear) and the second-source to the front (see Figure 23).

5.10.7Speaker-Attenuator and Mixing
A Mixing-stage is placed after each speaker-attenuator and can be set independently to mixing-mode. Having
a full volume for the Mix-signal the stage offers a wide flexibility to adapt the mixing levels.

5.10.8Audioprocessor Testing
During the Testmode, which can be activated by setting bit D
of the stereodecoder testing-byte and the audio-
0
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.
