8.3 Setting Digital Surround Delay
The CP500 automatically calculates a typical digital surround delay based on the
optical surround delay setting performed in Section 8.1. Actual theater geometry
affects the amount of surround delay required, therefore you may wish to set the
delay manually.
From the System Alignment menu, press the Digital Surround Delay key (SK5).
Rotate the front panel knob until the desired delay reading is displayed, then press
OK.
The following tables show approximate delay values (in milliseconds) based on
theater width and length. Setting of surround delay should be verified by listening at
various locations in the theater.
