SDP-40

Basic Operation

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

Receives infrared commands from the SDP-40 remote control. There are three LEDs located in this area as shown below. An amber LED blinks when a remote control command is received. A red LED lights when the A/D converters are overloading. And, a blue LED lights when the SDP-40 is powered on and activated – even if the FRONT PANEL DISPLAY menu STATUS parameter is set to ALWAYS OFF.

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.
