(3) Volume Coefficient Settings
[Relevant data] Coefficients: KiA (d6H), Kia (dcH), Kis (ddH)
The I/O levels and volumes are 2's complement format with a decimal point between D15 and D14, and
hexadecimal notation with D15 as MSB and D0 as LSB.
The coefficient and level relationships are as follows.
D15 to D0 are negative values, but the DSP calculation is (–1)
×
(D15 to D0).
(3)-1. Kia (dcH): 0dB = c000H
The I/O levels for 8000H to ffffH are obtained by the following formulas.
(Coefficient value) = [(–1)

I/O level = 20 log [coefficient value] dB
(3)-2. KiA (d6H), Kis (ddH): 0dB = 8000H
The I/O levels for 8000H to ffffH are obtained by the following formulas.
(Coefficient value) = [(–1)

I/O level = 20 log [coefficient value] dB
Unless otherwise specified, subsequent setting examples (Pro Logic mode) in these specifications assume
either:
Kia = d2b2H, KiA = 0000H, Kis = 0000H
or:
Kia = 0000H, KiA = 8000H, Kis = a563H
(4) Auto Input Balance Control
[Relevant data] Coefficient: Kx (d4H)
The auto input balance function is turned on and off by coefficient Kx (d4H).
