Mode of Operation
-
With the Sub 12D crossover mode on, the Sub 12D has an 80 Hz 12 dB per octave high
pass filter on the monitor outputs, including the digital left and right out, and a 24 dB per
octave low pass filter feeding the Sub 12D.
-
The cutoff frequency can be changed with software through the USB interface.
-
With the sub direct mode switch on, the crossovers are disabled; the left right outputs and
digital left right output are muted. This mode may be used when the Sub 12D is used with a
Blue Sky BMC or the Blue Sky AMC controller.
