SETUP

SUB L/R MONO, STEREO, NONE

SETUP SPEAKERS SET CROSSOVERS CUSTOM SETUP SUB L/R

Configures the Main Zone audio output connector labeled Subwoofer L/R for a speaker setup that includes one, two, or no subwoofer(s).

When a custom speaker setup is selected, the SUB L/R parameter opens the SUBWOOFERS L/R menu shown on page 3-26, which can be used to select the desired configuration for the Subwoofer L/R output connectors.

•Select MONO if the speaker setup includes one subwoofer. The SDP-40 sends low-frequency front, center, and surround channel signals to the Subwoofer L/R output connectors.

•Select STEREO if the speaker setup includes two subwoofers. The SDP-40 sends low-frequency front left, center, and sur- round left channel signals to the Subwoofer L output connec- tor and low-frequency front right, center, and surround right channel signals to the Subwoofer R output connector.

•Select NONE if the speaker setup does not include a subwoofer. The SDP-40 redirects low-frequency signals to the speakers with the lowest crossover points – unless the 5.1a BYPASS listening mode is activated. In this instance, configure the speaker setup with the associated DVD-A/SACD player to redirect low-frequency signals.
