Subwoofer
Several different applications are possible with the subwoofer circuit:
1.
Subwoofer filter OFF
a)
Main source stereo (AC coupled)
b)
Second source stereo (DC coupled)
c)
Main source mono differential (DC coupled)
d)
Second source mono-differential (DC coupled)
2.
Subwoofer filter ON
a)
Main source mono differential (DC coupled)
b)
Second source mono differential (DC coupled)
c)
Center speaker mode (filtered mono signal at SWL, unfiltered mono signal at
SWR)
In all applications the phase of the output-signal can be configured to be 0° or 180°. In the
center speaker mode only at the filtered output the phase is changed.
