Analog Mixer
ADC Multiplexers
The following sources are available for the Mono Out pin:
•

The stereo inputs are scaled by -6dB and then summed to provide an output that is the average of
the two inputs. The full scale output at mono out is designed to be about 0dBV. Like the stereo line
and headphone outputs, it is not possible to adjust to a +3dBV output level using a vendor defined
verb.
The mixer supports independent gain (-34.5 to +12dB in 1.5dB steps) on each input as well as inde-
pendent mutes on each input. The following inputs are available: The output of the mixer may be
sent to the ADC where the ADC record gain can adjust the volume. If the output of the mixer is sent
to an analog port, then a separate volume control is provided to adjust the output volume. This mixer
output volume control supports a gain range of -46.5dB to 0dB in 1.5dB steps. (Selecting -46.5dB
will automatically mute the output.)

The codec implements 2 ADC input multiplexers. These multiplexers incorporate the ADC record
gain function (-16 to +30dB gain in 1dB steps) as an output amp and allow a preselection of one of
these possible inputs:

DAC0 Output: When selected (by using the port connection list), the DAC0 left and right outputs
are summed together.
DAC1 Output: When selected (by using the port connection list), the DAC1 left and right outputs
are summed together.
DAC2 Output: When selected (by using the port connection list), the DAC2 left and right outputs
are summed together.
Mixer Output: When selected (by using the port connection list), the mixer left and right outputs
are summed together.
