OUTPUT MIXER CONTROL
The Output Mixer volume controls are described in Table 32 for the Left Channel and Table 33 for
the Right Channel. The gain of each of analogue input paths may be controlled independently in the
range described in Table 34. The DAC input levels may be controlled by the DAC digital volume
control - see “Digital to Analogue Converter (DAC)” for further details of this control.
