Default = 0 dB (No attenuation)
The Digital Volume Control allows the user to alter the signal level in 1 dB increments from +18 to -96 dB,
using the Digital Volume Control. Volume settings are decoded as shown in Table 8, using a 2’s comple-
ment code. The volume changes are implemented as dictated by the Soft and Zero Cross bits in the Pow-
er and Muting Control register. All volume settings less than - 96 dB are equivalent to muting the channel
via the ATAPI bits (See Section 5.10.4).
NOTE: Setting this register to values greater than +18 dB will cause distortion in the audio outputs.
Default = 0 dB (No Bass Boost)
The level of the shelving bass boost filter is set by Bass Boost Level. The level can be adjusted in 1 dB
increments from 0 to +12 dB of boost. Boost levels are decoded as shown in Table 9. Levels above
+12 dB are interpreted as +12 dB.
