The second press restores the volume in the Main Zone to its
original level. Mute level can be set in the VOLUME
CONTROL SETUP menu (see page 3-34).
The Mute LED lights whenever mute is activated either
manually or automatically by the unit. For example, the unit
will briefly activate mute when changing input types or
listening modes.
Main Input Selection Buttons select the input in the Main
Zone, and light a corresponding blue LED. When the unit is in
standby, pressing one of these buttons also activates the Main
Zone. (Zone 2 and the Record Zone will remain deactivated
until one of those inputs is selected.)
Main Off deactivates the Main Zone.
Zone 2 Input Selection Buttons select the input in Zone 2,
and light a corresponding amber LED. When the unit is in
standby, pressing one of these buttons also activates Zone 2.
(The Main and Record Zones will remain deactivated until one
of those inputs is selected.)
Zone 2 Off deactivates Zone 2.
Record Input Selection Buttons select the input in the Record
Zone, and light a corresponding red LED. When the unit is in
standby, pressing one of these buttons also activates the
Record Zone. (The Main Zone and Zone 2 will remain
deactivated until one of those inputs is selected.)

Basic Operation
SDP-40
The Front Panel Display indicates the current input name
(top-left); the current listening mode name (bottom-left); the
current input type (top-center); and the current volume level
(right). This 2 by 20 character display can be used to view the
menus, one menu item at a time. The up and down MENU
arrows can be used to scroll through all menu items, provided
the Main remote control command bank is active (see page
2-8)
The IR Receiver receives infrared commands from the remote
control. There are three LEDs located in this area: an amber
LED blinks when an infrared command is received; a red LED
lights when the analog-to-digital converters are overloading;
and a blue LED lights when the unit is on (even when the front
panel display is deactivated).
The Volume Knob adjusts the volume level in the Main Zone.
When adjustments are made, volume level is shown in dB on
the on-screen and front panel displays. A horizontal bar graph
illustrates adjustments.
The Mode Up and Down Buttons scroll through available
listening modes in the Main Zone. Pressing the Mode Up
button selects the previous listening mode; pressing the Mode
Down button selects the next listening mode. See page 2-17
for more information about mode selection using the Mode up
and down buttons.
Mute toggles between muting the volume level in the Main
Zone, and restoring the volume to its original level. The first
press lowers the volume level in the Main Zone and lights the
amber LED on this button. The message “MUTE ON” appears
in the top-left corner of the on-screen and front panel displays.
