SETUP
SDP-40
3-29
SUB L/R MONO, STEREO, NONE
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.
When a SYNTHESIS 7CH speaker setup is selected, the SUB L/R
parameter cannot be adjusted. The SDP-40 automatically config-
ures the Subwoofer L/R output connectors for a speaker setup that
includes one subwoofer.

SUB XOVER FULL, 30 to 120Hz, THX 80Hz, NONE
Assigns a crossover point for the Main Zone audio output
connectors labeled Subwoofer L/R.
When a custom speaker setup is selected, the SUB XOVER
parameter opens the SUB XOVER menu shown on page 3-26,
which can be used to select a crossover point for the Subwoofer L/R
output connectors. Select FULL to send a full-range signal to the
subwoofer. Otherwise, select the crossover point equal to the
lowest crossover point of the other speakers.
When a SYNTHESIS 7CH speaker setup is selected, the SUB XOVER
parameter cannot be adjusted. The SDP-40 automatically applies a
80Hz crossover point to the Subwoofer L/R output connectors.
