Mono Output
The MONO Output is connected to pin 32 and has an independent mute (see the Widget listing for
details). The MONO Output derives its input from the output of the summing node after the mono
mux. The following sources are available for the mono pin:
DAC0 Output: When enabled (by using port connection list), both DAC0 Outputs are summed
together.
