Audio Signal Processing

As with all EURO 4 models, audio processing is
provided by the MSP3410 IC2101. The MSP3410 is
designed as a Multi-standard Sound Processor used
in the processing of analogue and digital audio
signals. A full description of its operation can be found

7.1. Input Signal Processing Path
:
Pin 47 - ANA_In1
This signal input has not changed, the signal input via
pin 47 of the MSP IC2101 being fed directly from the
tuner SIF output.
:
Pin 37 / Pin 38 - SC3_In_L / _R
Again this input processing path has not changed, the
left and right audio signals fed from AV3 RCA
terminals being fed directly to the MSP.
:
Pin 39 / Pin 40 - SC2_In_L / R
This input processing path again has no change which
sees the left and right audio signals being fed from the
21 pin scart terminal of AV1 .

Although the internal processing of the MSP3410
IC2101 has not changed, the input and output
processing paths have, these being cover in the

:
Pin 41 - SC1_In_L
This left audio channel input which was originally fed

IC3151 pin 15 located on the H-Board (see chapter 4
section 9.5.2.).
:
Pin 42 - SC1_In_R
This right audio channel input which was originally fed
directly from AV2, is now fed from the audio switching
IC3151 pin 16 located on the H-Board (see chapter 4
