4. Volume Knob

Note:
When SDP-40 output levels have been properly cali-
brated, the +0dB volume level setting corresponds to
THX reference levels (75dB).
5. Mode & Buttons
Scroll to the previous and next available listening mode,
auditioning listening modes with the current Main Zone input
source. Scrolling occurs in the order shown on the MODE

the Main Zone two-line status. The SDP-40 automatically
activates the selected listening mode when scrolling stops.

to its original level. Pressing the Mute button once lowers Main
Zone volume level. The message "MUTE ON" appears on the

again restores Main Zone volume to its original level. The
VOLUME CONTROL SETUP menu MUTE LEVEL parameter can
