(7)-1. Volume Settings for Each Section
[Relevant data] Coefficients: KLV (00H), KRV (01H), KCV (02H), KSV (03H), KLm1 (04H), KRm1 (05H),
KLm2 (09H), KRm2 (0aH), KLd (0eH), KRd (0fH), KCd (10H), KSd (11H),
Kfb (12H), KDV1 (21H), KDV2 (22H), KDV3 (23H), KLRm1 (24H),
KLRm2 (25H), KLRm3 (26H), KTP1 (28H), KTP2 (29H), KTP3 (2aH),
KTP4 (2bH), KTP5 (2cH), KTP6 (2dH)
The format is the same as that described in "(3) Volume Coefficient Settings". The levels are as follows when
0dB = 8000H.
The I/O levels for 8000H to ffffH are obtained by the following formulas.
(Coefficient value) = [(–1)

D15 +
(Dn

)]
×
(–1)
I/O level = 20 log [coefficient value] dB
The above coefficients are normally applied as negative values, but positive values should be applied when
intentionally inverting the phase with TP1 to TP6, etc. In this case, the levels are as follows when 0dB = 7fffH.
The I/O levels for 7fffH to 0001H are obtained by the following formulas.
(Coefficient value) = [D15 +
(Dn
