Tone Control (Address 08h)
2.1 Bass Manager/Parametric EQ Control (Address 09h)
Treble Gain Level (Treb[3:0])
Default = 1000
Function:
Sets the gain/attenuation level of the treble shelving filter.The level can be adjusted in 1.5 dB steps from
+12.0 to -10.5 dB.
Bass Gain Level (Bass[3:0])
Default = 1000
Function:
Sets the gain/attenuation level of the bass shelving filter. The level can be adjusted in 1.5 dB steps from
+12.0 to -10.5 dB.
Freeze Controls (Freeze)
Default = 0
Function:
This function will freeze the previous output of, and allow modifications to be made to the master volume
control (address 57h), channel X volume control (address 58h - 5Ah), and bi-quad coefficient registers for
channel A, and channel B (address 0Ah - 54h) without the changes taking effect until the Freeze bit is
disabled. To make multiple changes in these control port registers take effect simultaneously, enable the
Freeze bit, make all register changes, then disable the Freeze bit.
