    Here's How Eventide Takes the Hassles Out of Radio Talk Show Production With the World's Most Advanced Broadcast Delay.

    Advanced Catch-up circuitry For Unprecedented Performance

    Eventide's patented automatic catch-up feature, first introduced on our now-classic BD955, solves the problem of getting back into delay after a segment is "DUMPED." The DUMP button is pushed to prevent an obscenity or other undesireable utterance from reaching the air. The obscenity is deleted and delay goes to zero. Then, without further operator intervention, the unit starts imperceptibly adding delay back into the program audio, with no program interruption. Thus, the delay "safety margin" is automatically rebuilt.

    In the BD980, this catch-up process has been dramatically enhanced, employing intelligent algorithm digital splicing techniques, field-proven in our famous Eventide Harmonizer® audio effects devices. As a result, the BD980 provides catch-up quality light-years ahead of earlier designs. Catch-up can be accomplished far faster and cleaner. With the BD980, the process is virtually undetectable, even to the careful listener. Two modes of catch-up are available, each adjustable for catch-up rate. In PAUSE mode, the unit adds delay for catch-up only during silent periods.

    Unlike other schemes which manufacturers have attempted, the BD980 calculates the optimum length of each delay "slice" to be added, so that natural speech patterns are maintained. In PAUSE/OSCILLATE mode, the BD980 operates on the audio itself, as well as the pauses. This mode is especially useful when working with music or fast speech which has few true pauses. Patented Eventide circuitry makes the process amazingly fast and clean, far better than catch-up has ever been before. And, as you can see from the specs of the BD980, audio quality is better than ever as well.

    RAMP TO ZERO Mode Gets You Out Of Delay Effortlessly.

    With previous broadcast delays, getting out of delay could be quite a hassle. Typically, the operator would have to finish the delay segment audio, immediately switch the monitor from pre-delay to post-delay, wait until he heard the last delayed word, then switch the digital delay out of the line and continue with the program. No fun in any case, and especially in combo operation - things could get quite hectic.

    To accomplish the same thing with the BD980, just push the RAMP TO ZERO button, and go right "on with the show." It's that simple. The RAMP TO ZERO mode initiates a "catch-down" process which automatically (that's easy) and inaudibly (that's the hard part only Eventide does perfectly) decrements delay until it reaches zero. With the BD980's RAMP TO ZERO mode, frantic switching and monitoring hassles are a thing of the past.

    WAIT & EXIT Makes "Impossible" Switches Easy.

    Switching from delay operation to a traffic report, remote broadcast or other event which waits for an on-air cue to start (and then getting back into delay afterwards) is really tough with conventional broadcast delays. Many stations don't even attempt such switches, certainly not on a routine "traffic report every 20 minutes basis." The BD980's exclusive WAIT & EXIT mode solves this problem ingeniously. When it's time for traffic, for example, just say your last word and push the WAIT & EXIT button. The BD980 automatically "plays out" the remaining stored audio delay and then, after your last word comes out on-air, the unit DUMPS to real time. The traffic reporter in the field hears the on-air cue and starts talking. At the end of the traffic report, you just push the WAIT & EXIT button a second time and the unit goes into CATCH-UP mode, quickly rebuilding delay. This feature is also ideal for sports remotes and network news on the hour (so that it really starts precisely on the hour).

    It's A Time Compressor, Too!

    The BD980 can also be used to shorten or lengthen an audio segment by up to ten seconds. For example, a 60 second national commercial spot can be easily compressed to 55 1/2 seconds to accommodate a local retailer's tag. Or a too-short or over-long music bed can be time compressed or expanded to fit a promo. TIME-SQUEEZE operation is simple. To delete 4.5 seconds, as in the example above, just switch to MANUAL DELAY mode, enter 4.5 seconds on the alphanumeric display, and start your tape. At the start of audio, push the RAMP TO ZERO button. When the spot is over, it will have been compressed by exactly 4.5 seconds.

    The BD980 offers several key advantages over conventional stand-alone time compressors for audio. Unlike these devices, a variable speed tape recorder is not required for time compression with the BD980. That means you can go cart-to-cart, disc-to-cassette, even live-to-tape. Also, the BD980 eliminates phasing problems that plague conventional stereo time compressors, especially when listening in mono. And the BD980 costs many thousands less than single-purpose conventional time compressors.

    Variable Delay Time for Maximum Flexibility.

    For routine, automatic operation, such as when CATCH-UP, RAMP TO ZERO or WAIT AND EXIT modes are employed, the BD980 can be set to provide 4, 6, 8, or 10 seconds of delay. This unusually wide range of delay times affords maximum flexibility to the program director and talent to choose the amount of delay which best fits their operating style (and reaction speed). To prevent unauthorized tampering, this delay adjustment is an internal DIP switch.

    In MANUAL delay mode, the BD980 can be set from the front panel, to any delay from zero to ten seconds in one millisecond steps. In this mode, the BD980 functions as a conventional digital delay, ideal for production effects such as echo and double tracking. This mode is also used to precisely set the amount of time to be added or deleted when the unit is used for time compression.

    Readout And Remote Capabilities Add Operating Ease.

    The BD980's large alphanumeric display can be easily viewed even from across the studio. The readout displays >>SAFE<< whenever the maximum delay margin is active. After a DUMP to real time, the readout is continually updated to show the present amount of delay, as catch-up proceeds. The display also indicates current settings in other modes, and functions as part of the BD980's extensive self-test facilities.

    A rear panel remote socket provides remote access to major operating functions of the BD980. This socket is pin-compatible with the remote facility of the Eventide BD955.
