Audio delay processor
Precision Delay addresses a range of radio applications, such as drift between analog and HD Radio transmission signals; broadcast repeater synchronization; and delaying programs across time zones. It uses delay status readings from compatible Belar and Audemat modulation monitors to automatically adjust delay of the analog broadcast signal for synchronization with the HD Radio signal. In addition to the blend issue, some stations choose not to delay their analog signals during local sports events, so listeners can hear the analog signal in real-time with the game. Not only does Precision Delay provide both the inaudible exit from delay and precise post-game resynchronization with the HD Radio signal required by “ballgame mode,” it does so while leaving PPM watermarking intact, so stations don’t have to sacrifice ratings during the delay transition. Serial data over IP or RS-232, as well as contact closures, can also be delayed insync with audio.

What the Pick Hits judges had to say:
“The exceedingly long delay with no moving parts is just what I need.”
“Frame-level delay adjustments, and it talks to Audemat and Belar monitors; perfect for HD Radio.”
