WIRING CONNECTIONS TO THE SDEC
22
• Turn on all equipment except the surround processor. At this time all Synthesis components should remain in standby.
• Now turn on the surround processor. After a few seconds, the Synthesis components should power up. First, the SDEC
will go from standby to on, followed by the amplifiers, one channel at a time.
• The first time SDEC is powered, it may take up to 30 seconds to “boot”. After system calibration is complete, boot time
is reduced to about ten seconds. When boot is complete, the red light around the power switch goes off, and an amber
LED in the center of the front panel comes on.
• Select an active program source. At this time, check that all channels are working. Now select another “effect” on the
surround processor that triggers a mode change. Confirm that all channels are still operating normally. If all channels
are working as anticipated, you are ready for connection to the Digital Audio Calibration System for equalization. Should
time not permit system calibration immediately, it can be used “as is” temporarily. The SDEC will simply pass signals
through with no signal processing.
• If the system is not performing as expected, refer to “Troubleshooting” in Section 4.7.
Power the system up for the first time:
With all power switches “off”, plug all equipment into power outlets. Turn on the SDEC by pressing the front panel push
button. Turn on the controller (typically first with a rear-panel master power switch, after which it will go through an initial-
ization procedure, then from a front panel switch or remote control). The red light around the SDEC’s power switch should
go off and the yellow LED in the center of its front panel should light within 30 seconds. (After the SDEC is programmed,
the turn-on time is considerably shorter.) After a few seconds, the rest of the system should be on and ready for operation.
• Select a convenient source. The SDEC should route all channels to the appropriate loudspeakers, but will provide no
driver, time, or room correction.
• It is now ready for connection to the Digital Audio Calibration System for complete setup and equalization. Should
time not permit system equalization immediately, the system can be used “as-is” until the process can be completed.
The SDEC will simply pass signals through, with no equalization.
