Basic Operation
SDP-40
2-3
1. Standby Button
Activates and deactivates standby mode when the SDP-40 is
powered on with the rear panel power switch. The standby button
performs no function when the SDP-40 is powered off with the rear
panel power switch.
When standby mode is activated, pressing the standby button
deactivates standby mode and activates the SDP-40 including
all zones that were activated during the previous operating
session. When standby mode is deactivated, pressing the
standby button activates standby mode and deactivates the
SDP-40. The red standby button LED lights to indicate that
standby mode is activated.
Note:
Power is still supplied to the SDP-40 when standby
mode is activated.
2. Front Panel Display
Indicates the current input, listening mode, input source, and
volume level. This 2 x 20 character display can also be used to
view messages and menus, one line at a time.
3. IR Receiver
4. Volume Knob
Adjusts volume level in all zones.
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
ADJUST menu. Pressing the Mode button scrolls upward
through available listening modes, and pressing the Mode
button scrolls downward through available listening modes.
For example, if a 2-channel source is present, the Mode and
buttons scroll through available 2-channel listening modes. The
selected listening mode appears in the bottom-left corner of
the Main Zone two-line status. The SDP-40 automatically
activates the selected listening mode when scrolling stops.
6. Mute Button
Mutes Main Zone volume level and restores Main Zone volume
to its original level. Pressing the Mute button once lowers Main
Zone volume level. The message "MUTE ON" appears on the
on-screen and front panel displays. Pressing the Mute button
again restores Main Zone volume to its original level. The
VOLUME CONTROL SETUP menu MUTE LEVEL parameter can
be used to set mute levels.
