SETUP SPEAKERS CUSTOM SETUP

Selecting the SPEAKER SETUP menu CUSTOM SETUP option opens the CUSTOM SETUP menu shown above, which can be used to configure the Main Zone audio output connectors for a custom speaker setup. The CUSTOM SETUP menu allows the selection of independent crossover points for each Main Zone audio output connector. Refer to the the paragraph below for more information about determining crossover points.

Determining Crossover Points

The CUSTOM SETUP menu shown above 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 on the next page indicate the frequency response of these crossover points.

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

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