Notice)
In the partial power down mode, master volume is not muted, so all analog input sources and
enabled digital sources (i.e. FM, SB, WSS etc.) can be heard. Note that AUX2 inputs are
exceptions in this regard since setting FMDAC bit inhibits the inputs altogether.
3D Enhanced control(WIDE) (R/W):
Index D7 D6 D5 D4 D3 D2 D1 D0
14h - WIDER2 WIDER1 WIDER0 - WIDEL2 WIDEL1 WIDEL0
This register specifies the wide level of the 3D enhanced control.
WIDER2-0... These bits determine the wide level of 3D enhanced control on Right
Channel by 8 step (if WIDER2-0=0, 0%, and WIDER2-0=7, 100%).
WIDEL2-0... These bits determine the wide level of 3D enhanced control on Left
Channel by 8 step (if WIDEL2-0=0, 0%, and WIDEL2-0=7, 100%).
default:00h
3D Enhanced control(BASS) (R/W):
Index D7 D6 D5 D4 D3 D2 D1 D0
15h - BASSR2 BASSR1 BASSR0 - BASSL2 BASSL1 BASSL0
This register specifies the bass level of the 3D enhanced control.
BASSR2-0... These bits determine the bass level of 3D enhanced control on Right
Channel by 1.5dB step(Max. 10.5dB).
BASSL2-0... These bits determine the bass level of 3D enhanced control on Left
Channel by 1.5dB step(Max. 10.5dB).
default : 00h
3D Enhanced control(TREBLE) (R/W):
Index D7 D6 D5 D4 D3 D2 D1 D0
16h - TRER2 TRER1 TRER0 - TREL2 TREL1 TREL0
This register specifies the treble level of the 3D enhanced control.
TRER2-0... These bits determine the treble level of 3D enhanced control on Right
Channel by 1.5dB step(Max. 10.5dB).
TREL2-0... These bits determine the treble level of 3D enhanced control on Left
Channel by 1.5dB step(Max. 10.5dB).
default : 00h
Notice)
The 3D Enhanced control parameter registers at index 14h, 15h and 16h must be 00h, when
doing the Wide Stereo portion in power down mode (setting SA3 control register, index 13h,
WIDE bit to “1”).
