DIR911 Digital Instant Recall

Not Just Instant Recall, Instant Intelligibility.

Eventide, the company that invented the first digital tape audio logger, has now turned its attention to instant recall devices. We found that most available units were pretty much alike, and they all had one glaring omission. Operators most often turn to their instant recall unit when the incoming telephone call or radio transmission is difficult to understand, often because the caller is speaking too fast or the audio sounds garbled. But most available instant recall units can only play back calls "as-is." The operator can hear it again, but not more clearly.

Intelli-Clear^tm Speed Control

Now Eventide, drawing on its expertise as one of the world's leading suppliers of audio processors to the professional recording and broadcast fields, has changed all that with Intelli-Clear speed control. This feature lets the operator slow down the playback (or speed it up) without changing the pitch or degrading the sound quality. This breakthrough, made possible by advanced DSP (digital signal processing) circuitry, is nothing like varispeed controls you may have heard in the past. The degraded audio quality of other varispeed controls often makes audio harder to understand. But with Intelli-Clear slowing down the replay actually increases intelligibility. Operators can frequently understand speech that had been hopelessly garbled.

To make Intelli-Clear even more useful, Eventide engineers rethought the conventional rewind/fast forward controls found on other recall devices. They're useful on a tape recorder, but on a recall unit, conventional rewind/fast forward buttons usually overshoot the desired segment within a message, resulting in the operator having to "hunt and peck" awkwardly until the right segment is found. But the Eventide DIR911's rewind and fast foward buttons work differently. Each touch advances or backs up the message by 1.25 seconds. Tap the rewind button four times, and you jog back five seconds. Simple, precise, and easy to use -- ideal for high-pressure public safety operations.

Large Data LCD

The DIR911's backlit 4 line x 40 character LCD screen, much larger than those on other recall units, is easier to read and shows a wider range of information. The screen displays a wide variety of information, includingall ANI (Automatic Number Identification) and CLID (Calling Party Identification) data, and uniquely, the phone number captured from ALI (Automatic LocationIdentification) data. Full ALI data will be shown on a connected external display. For operating ease, the bottom line of the LCD dynamically labels four "softkey" buttons with the proper designations for each operatingmode.
