The AUTOBALANCE register enables or dis-
ables the autobalance for Pro Logic:
0 Autobalance ON
1 Autobalance OFF
Other values set Autobalance OFF
The WIDE_SURROUND register enables or
disables the Wide Surround for Pro Logic:
0 Wide Surround ON
1 Wide Surround OFF
Other values set Wide Surround OFF
The PINK_NOISE register enables or disables
the pink noise for Pro Logic:
0 Pink noise OFF
1 Pink noise ON
Other values set Pink noise ON
If the PROCESS register has not been set with
the PROLOGIC value, the Pink Noise is any-
way OFF.
The DELAY register contains the delay in ms
for the surround between 0 and following val-
ues (grater values are undefined):
Frequency
Max value
32kHz
53ms
44.1kHz
38ms
48kHz
35ms
The default is 20ms for all frequencies.
The DELAY_RATIO register defines the period
of the delayed signal mixed with the original
one.
