LMX1
LX1A4:0
Left Auxiliary Input #1 Attenuate Select. The least significant bit of this gain/attenuate select represents 1.5 dB.
LX1A4:0 = 0 produces a +12 dB gain. LX1A4:0 = “01000” (8 decimal) produces 0 dB gain. Maximum attenua-
tion is –34.5 dB. See Figure 10.
res
Reserved for future expansion. Always write zeros to these bits.
LMX1
Left Auxiliary #1 Mute. This bit, when set, will mute the left channel of the Auxiliary #1 input source. This bit
powers up set.
This register’s initial state after reset is “1xx0 1000.”

RX1A4:0
Right Auxiliary Input #1 Attenuate Select. The least significant bit of this gain/attenuate select represents
1.5 dB. RX1A4:0 = 0 produces a +12 dB gain. RX1A4:0 = “01000” (8 decimal) produces 0 dB gain. Maximum
attenuation is –34.5 dB. See Figure 10.
