BM_LR2SUM_LEVEL
0xA6
2 Bytes
Left and Right channel into Bass Sum mixing level register.
The each mixing level register consists of mixing polarity (1-bit) and mixing level
coefficient (7-bit). MSB is the mixing polarity (“0” : +, “1” : -) and LS 7-bit is the
mixing level coefficient.
Table A-2 shows the relations between the register value and mixing level.
[7..0]: Left channel input into Bass Sum mixing level.
[15..8]: Right channel input into Bass Sum mixing level.
Default = 0x4242 ((+) -15dB, (+) –15dB)
BM_LSRS2SUM_LEVEL
