Operation
4.1 Front-Panel Switches
The two front-panel switches, Film and Digital Media, select a user-determined input
format based on the cinema processor settings, or a digital media input determined by
the setup software (PCM, Dolby
®
Digital, or Dolby E bitstreams).
4.2 Power
A mains power switch is located on the rear-panel power inlet module. It should
remain in the ON position, with power normally controlled from a centrally switched
facility location. The power-on mode is “Film.”
A five-second self-test runs on power-up. The output is muted during the self-test.
4.3 Surround Delay
When the audio comes from a digital media source, it is necessary to apply a delay to
the surround channels, based on the dimensions of the auditorium. The setup software
allows an adjustment of 0 to 150 ms in 1 ms steps. The default setting at the factory
is 0.
