PRELIMINARY DATA SHEET
6.5. Manual/Compatibility Mode:
6.5.1. Additional Channel Matrix Modes
This table shows more modes for the channel matrix
registers.
The sum/difference mode can be used together with
the quasi-peak detector to determine the sound mate-
rial mode. If the difference signal on channel B (right)
is near to zero, and the sum signal on channel A (left)
is high, the incoming audio signal is mono. If there is a
significant level on the difference signal, the incoming
audio is stereo.

6.5.2. Volume Modes of SCART1 Output
6.5.3. FM Fixed Deemphasis
Note: This register is initialized during STANDARD
SELECTION and is automatically updated when Auto-
matic Sound Select (MODUS[0]=1) is on.
6.5.4. FM Adaptive Deemphasis
Note: This register is initialized during STANDARD
SELECTION and is automatically updated when Auto-
matic Sound Select (MODUS[0]=1) is on.
6.5.5. NICAM Deemphasis
A J17 Deemphasis is always applied to the NICAM sig-
nal. It is not switchable.
