JBL SYNTHESIS SDP-40HD - Manual (Page 15)

SDP-40HD Basic Operation
2-3
1 STANDBY BUTTON
Use the Standby button to activate or deactivate standby mode.
The Standby button performs no function when the SDP-40HD rear
panel power switch is powered off. When standby mode is
deactivated, all SDP-40HD zones that were active during the last
session are reactivated. The red LED in the Standby button lights to
indicate that standby mode is activated. Power is still supplied to
the SDP-40HD when it is put into standby mode.
2 FRONT-PANEL DISPLAY
Use the front-panel display to view the current input, listening
mode, input source, and volume level. The 2 x 20 character display
also functions as a display for messages and menus.
3 IR RECEIVER
The IR receiver accepts infrared commands from the SDP-40HD
remote control. There are three associated LEDs.
• The amber LED blinks when a remote control command is
received.
• The red LED lights when the A/D converters are overloading.
• The blue LED lights when the SDP-40HD is powered on and
activated – even if the FRONT PANEL DISPLAY menu STATUS
parameter is set to ALWAYS OFF.
4 VOLUME KNOB
Use the volume knob to adjust volume level in all zones.
Note:
When SDP-40HD output levels are properly calibrated, the +0dB volume
level setting corresponds to the THX reference level (75dB).
To adjust the Main Zone volume level:
Rotate the volume knob clockwise or
counterclockwise to increase or decrease the
volume level in 1dB increments. A horizontal
bar graph indicating the current Main Zone volume level appears in
the on-screen and front-panel displays. The Main Zone volume
range is –80 to +6dB.
To adjust the Zone 2 or Record Zone volume level:
1. Press and hold the front panel Zone 2 or Record Zone input selec-
tion button that corresponds with the current input source. For
example, if the current input source is DVD1, press and hold the
Zone 2 or Record Zone DVD1 input selection button.
2. Rotate the volume knob clockwise or
counterclockwise to increase or decrease
the volume level in 1dB increments. A hor-
izontal bar graph appears on the on-
screen and front panel displays. The Zone
2 or Record Zone volume ranges are –80
to +6dB.
3. When the Zone 2 or Record Zone volume level has been set,
release the input selection button.
Remote control input selection buttons cannot be used to select
Zone 2 or Record Zone volume level adjustment, even if the Zone 2
or Record Zone command bank is activated.
