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.
