Ayre Acoustics DX-7 - Manual (Page 33)

Command Functions
The DX-7 may either be controlled by the remote
control via a receiver on the front panel or by a
system controller via the Control Port. A small
toggle switch on the rear panel selects which mode
is active.
For normal use, set this switch to “IR Receiver”.
Set the switch to “Control Port” only when using
a custom programmed system controller.
Command files are available from the Ayre factory
in both Crestron and Pronto (CCF) format. These
files include discrete on/off commands.
DVD Aspect Ratio Information
All DVDs use one of three aspect ratios; standard,
widescreen, or letterbox. Each DVD has its aspect
ratio coded in the disc. The Control Port can
transmit this information to a system controller so
that the aspect of the video display can be
automatically adjusted to match the disc.
A few DVDs have incorrect aspect ratio codes.
These discs will still require manual adjustment of
the video display’s aspect ratio.
