NAB Booth #N502 FOR IMMEDIATE RELEASE

EVENTIDE INTRODUCES HIGH PERFORMANCE SYNCHRONIZATION DELAY FOR HD

LAS VEGAS, NEVADA, April 18, 2005 -

Eventide today announced the introduction of the HD-ready BD600 broadcast delay. HD broadcasting requires subsample synchronization between digital and analog signal transmission in order to maintain a seamless, artifact-free listener experience. The BD600 offers MicroPrecision Delay which provides a ten-second delay, with superfine delay adjustment down to 100 nanosecond increments, for synchronizing analog and digital signals for HD installations.

"Eventide's first audio product in 1971 was the 1745 delay which was used in broadcast. The BD600 is the latest in over thirty years of dependable, high-quality delays for broadcast and is the best sounding and most flexible delay we have ever made. Installed at the station or at the transmitter, the BD600 offers remote controllability, as well as the ability to ramp in and out of MicroPrecision Delay," said Eventide vice president of sales and marketing, Ray Maxwell. "The BD600 has two separate applications. Therefore we've included the essential features for HD analog and digital synchronization, or for obscenity protection for live radio shows all with unsurpassed fidelity and reliability."

Eventide's embrace of HD is highlighted by the introduction of the BD600 broadcast delay. The BD600 offers its new MicroPrecision Delay for real-time synchronization between analog and digital signals while on-air, without audible artifacts. With the 24-bit Eventide BD600, broadcasters can insert the highest quality delay after the exciter for HD radio synchronization or in the control room to keep offensive material off the air.

HD compatibility is the latest innovation in over thirty years of providing high-quality delays for broadcast applications. The BD600 is the first Eventide broadcast delay to incorporate HD synchronization capability to ensure the highest quality listener experience for broadcasters upgrading to HD.
