10.6. Dynamic Range Control  
Dynamic range control can be turned on or off with programmable compression threshold and  
attack/release rates. The threshold parameters of DRC can be controlled separately for channel 1/2  
and channel 3. For detailed setting, please refer to the system register Addresses 0x1C~0x25 and  
refer to the BQ ROM addresses in Table 7.
