Custom Speaker Setups

Selecting the CROSSOVER SETUP menu CUSTOM SETUP option
opens the CUSTOM SETUP menu shown above, which can be used
to assign independent crossover points for each Main Zone audio
output connector. Crossover points can be selected in 10Hz
increments within a 30 to 120Hz range. With the exception of THX
80Hz, all crossover points activate a 24dB-per-octave filter. The
graphs shown on the next page indicate the frequency response of
each crossover point.

To configure a custom speaker setup:

Select the crossover point closest to the low-frequency rating
of the associated speakers. For instance, set to FRONT L/R
parameter to the crossover point closest to the low-frequency
rating of the front speakers.

Setting Crossover Points

(continued from page 3-21)

Select the subwoofer crossover point equal to the lowest
crossover point of the other speakers. For instance, if CUSTOM
SETUP menu parameters are set as shown above, set the SUB
XOVER parameter to 40Hz – the lowest crossover point of the
other speakers.

In general, low frequencies will be redirected from the speakers
with the highest crossover points to the speakers with the lowest
crossover points. Low-frequency signals lower than the lowest
crossover point will be redirected to the subwoofer. If the lowest
crossover point is FULL, low-frequency signals, excluding LFE
information, will not be redirected to the subwoofer.
