VOLUME CONTROL (XX_VOL)
Volume control (addresses 07h, 08h, 0Ah, 0Bh, 0Dh, 0Eh)
Default = 00
00 - Single-Speed Mode (4 to 50 kHz sample rates)
01 - Double-Speed Mode (50 to 100 kHz sample rates)
10 - Quad-Speed Mode (100 to 200 kHz sample rates)
11 - Direct Stream Digital Mode
Default = 0
0 - Disabled
1 - Enabled
Default = 0 (No attenuation)
The Digital Volume Control registers allow independent control of the signal levels in 1 dB increments
from 0 to -127 dB. Volume settings are decoded as shown in Table 4. The volume changes are imple-
mented as dictated by the Soft and Zero Cross bits. All volume settings less than -127 dB are equivalent
to enabling the MUTE bit.
Selects the required range of input sample rates or DSD Mode. When DSD mode is selected for any
channel pair then all pairs will switch to DSD mode.
The Digital-to-Analog converter output will mute when enabled. The quiescent voltage on the output
will be retained. The muting function is effected, similar to attenuation changes, by the Soft and Zero
Cross bits. The MUTE pins will go active during the mute period according to the MUTEC bits.
