In standby mode, audio passes through with no delay. When the DD540 is switched on, the signal is output with your selected delay (0-680 milliseconds).
Automatic input selection means whichever source is operating will be output. If the source changes, the delay also changes to the setting stored for that input. This is extremely useful where each souce requires a different delay.
Thanks to these features, you can enjoy lip sync error-free viewing, leaving the DD540 alone most of the time. When you do need to change settings, full command is available via the remote control.
Other facilities include 12 delay presets (6 per input), adjustable display brightness, and manual input selection if needed.
Users who demand full integration with their A/V systems are catered for via a comprehensive set of discrete IR commands that can be sent from learning remote controls, e.g. Pronto.
