Las Vegas, NV (April 15, 2013)-At the 2013 NAB Show, 25-Seven Systems showed its Precision Delay, which now offers up to four hours of sample-accurate delay.
Precision Delay provides a solution for delaying programs across time zones, while protecting the integrity of PPM codes during delay builds and exits. Its Watermark Safe Mode is said to handle the time-based structure of PPM encoding.
"We designed Precision Delay for a range of radio applications", notes Geoff Steadman, president of 25-Seven. "In addition to helping stations and networks delay programming, Precision Delay can also be used to address drift between analog and HD Radio transmission signals."
When integrated into the HD Radio air-chain, Precision Delay uses delay status readings from compatible Belar and Audemat modulation monitors to adjust the delay of the analog broadcast signal for synchronization with the HD Radio signal.
Precision Delay has a built in web-server for control from anywhere and standard digital, analog and Livewire IP audio interfaces. Serial data over IP or RS232, as well as contact closures, can be delayed in sync with the audio.
