6.24 DRC Bypass Registers (0xA2 – 0xA9)
DRC bypass/inline for channels 1, 2, 3, 4, 5, 6, 7, and 8 are mapped into registers 0xA2, 0xA3, 0xA4,
0xA5,0xA6, 0xA7, 0xA8, and 0xA9. 8bytes are written for each channel. Each gain coefficient is in 28-bit
(5.23) format so 0x00800000 is a gain of 1. Each gain coefficient is written as a 32-bit word with the upper 4
bits not used.
To enable DRC for a given channel (with unity gain), bypass = 0x00000000 and inline = 0x00800000.
To disable DRC for a given channel, bypass = 0x00800000 and inline = 0x00000000.
