Selecting the SPEAKER SETUP menu CUSTOM SETUP option opens
the CUSTOM SETUP menu, which can be used to configure the
audio output connectors for a custom speaker setup. The
CUSTOM SETUP menu allows the selection of independent
crossover points for each audio output connector.
Determining Crossover Points
The CUSTOM SETUP menu allows independent crossover points
to be assigned for each audio output connector. Crossover points
can be selected in 10Hz increments within a 30Hz–120Hz range.
With the exception of THX 80Hz, all crossover points activate a
24dB per-octave filter. The graphs on the next page indicate the
frequency response of these crossover points.

For each audio output connector, select the crossover point closest
to the low-frequency rating of the associated loudspeaker. For the
output connector labeled Subwoofer, select the crossover point
equal to the lowest crossover point of the other loudspeakers.
