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 use 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 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, including all ANI (Automatic Number Identification)
and CLID (Calling Party Identification) data, and uniquely, the phone
number captured from ALI (Automatic Location Identification) 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 operating mode.
Fully Featured:
Eventide has equipped the DIR911 with a full
64 minutes of standard digit al RAM storage, at the preferred 32Kbs
digital sampling rate. An addition al 64 minutes is optionally available.
The Eventide DIR911 also provides password security which protects system
setup parameters from being accidentally changed or erased. The DIR911
is available as a single or dual unit to fit a standard 5.25" X
19" rack mount. A desktop model is also available.
The choice in instant recall units for public safety applications
has now been made clear. The DIR911 with Intelli-Clear speed control
is in a class by itself.
