Analog Input Options
This option selects the appropriate MUX for the respective left or right channel.
• MUX1 selects the L-channel source (AIN1/AIN2/AIN3).
• MUX2 selects the R-channel source (AIN1/AIN2/AIN3).
D2S Select Options
The analog input can be configured as single-end or differential. Select the D2S drop-down menu to
choose between differential or single-ended inputs. If differential is selected, AIN1L and AIN1R are used
as differential inputs.
Analog Mixer Options
The analog input, DAC output, and other channels of the analog input can be combined as an analog
mixer source. To combine the sources, select the Analog Mixer menu to combine the DAC output and
incoming stereo or mono analog signal input through PG1/PG5 or PG2/PG6.
Mic Boost Options
This checkbox sets (or resets) the +20dB microphone pre-amp PG1 (L-ch) or PG2 (R-ch).
