R7: Record Mixer Right (Mixer 2) Control 1, 16,397 (0x400D)
This register controls the gain boost of the right channel differential PGA input and the gain for the right channel auxiliary input in the
record path. The right channel record mixer is referred to as Mixer 2.

Right single-ended auxiliary input gain from the RAUX pin in the record path, input to Mixer 2.
Description
Right channel differential PGA input gain boost, input to Mixer 2. The right differential input uses the RINP
(positive signal) and RINN (negative signal) pins.

Description
Left channel differential PGA input volume control. The left differential input uses the LINP (positive signal) and
LINN (negative signal) pins. Each step corresponds to a 0.75 dB increase in gain. See Table 69 for a complete list
of the volume settings.

Left differential input mute control.
0 = mute (default).
1 = unmute.
Left differential PGA enable. When enabled, the LINP and LINN pins are used as a full differential pair. When
disabled, these two pins are configured as two single-ended inputs with the signals routed around the PGA.
0 = disabled (default).
1 = enabled.
