CUSTOM SETUPS
Selecting the SPEAKER SETUP menu CUSTOM SETUP option opens
the CUSTOM SETUP menu, which assigns independent crossover
points for each Main Zone audio output connector. Crossover
points can be selected in 10Hz increments within a 30 to 120Hz
range. 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 example, set the FRONT L/R
parameter to the crossover point closest to the low frequency
rating of the front speakers.
• Select the subwoofer crossover point equal to the lowest
crossover point of any of the other speakers. For example, if
CUSTOM SETUP menu parameters are set as shown above, set
the SUB XOVER parameter to 80Hz – the lowest crossover point
of the other speakers.
In a custom setup, low frequencies are generally redirected from
speakers with the highest crossover points to speakers with the
lowest crossover points. Signals lower than the lowest crossover
point are redirected to the subwoofer. If the lowest crossover point
is FULL, low frequency signals, excluding LFE information, are not
redirected to the subwoofer.
Low frequencies between the Subwoofer L/R and any or all of the
other speaker channels can be duplicated. To do this, select the
FULL + SUB crossover setting for the front, center, side or rear
speakers. Making this selection can result in excessive bass.
