Mono Output
RESET#
The Mono Out port source selection, power state, and mute characteristics are all independently
controlled by the mono output port controls. EQ does not apply to this path. An internal 2nd order
band-pass filter is provided to restrict the output frequencies when using mono out to drive an exter-
nal amplified sub-woofer.
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. It is not possible to
adjust to a +3dBV output level.
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.
Mixer Output: When selected (by using the port connection list), the mixer left and right outputs
are summed together.
