SETUP SPEAKERS CUSTOM SETUP

Selecting the SPEAKER SETUP menu CUSTOM SETUP option opens the CUSTOM SETUP menu, which is 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 are selected in 10Hz increments within a 30Hz to 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 fre- quency response of these crossover points.

The THX 80Hz crossover point activates a 12dB per-octave filter for the audio output connectors labeled Front L/R, Center, Side L/R and Rear L/R, and a 24dB-per-octave filter for the audio output connector labeled Subwoofer.

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