Record Gain Register (Index 1Ch)
The Record Gain register is for the stereo input. Each step corresponds to 1.5 dB with 22.5 dB corresponding
to 0F0Fh. The MSB of the register is the mute bit. When this bit is set to 1, the level for that channel is set
to maximum attenuation.
The default value of this register is 8000h which represents 0-dB gain with mute on. The Record Gain
register definitions are listed in Tables 2–11.
