Eventide DIR911t Digital Instant Recall Recorders - DISCONTINUED

Eventide  DIR911t Digital Instant Recall Recorders
Manufacturer P/N: DIR911t





Eventide-the company that invented the digital voice audio logger-turned its attention to instant recall devices and found that most units had one glaring omission. When the incoming telephone call or radio transmission is difficult to understand, the operator can play it again, but can't hear it more clearly.

IntelliClear Variable Speed Control

Drawing on our expertise in professional recording and broadcasting, we changed that with the IntelliClear™ variable 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 the slow speed button offered by other units, which often makes audio even harder to understand. Slowing down the replay with IntelliClear actually increases intelligibility. Operators can frequently understand speech which had been hopelessly garbled.

To make IntelliClear even more useful, Eventide rethought the conventional rewind/fast forward controls found on other recall devices, which overshoot the desired segment within a message making the operator hunt and peck awkwardly until the right segment is found. The DIR911T's rewind and fast forward work differently; the single control wheel located beside the recall button provides precise jogging backward and forward by simply turning the wheel to the left or right. It's fast and easy-to-use, and is ideal for high-pressure public safety operations.

Large Display

The DIR911T's back-lit 4 line x 40 character LCD screen is much larger than those on other recall units, and shows a wider range of information. Telephone numbers can be captured from DTMF, Caller ID, or ALI data stream, and will appear on the display. All message information such as time/date, message number, message lengths, etc. are clearly shown. For operating ease, the bottom line of the LCD dynamically labels four soft key buttons with the proper designations for each function.

The DIR911T can be installed as a compact desktop unit or optionally as a 5.25 x 19 single or dual rackmount. The choice in instant recall units for public safety applications is clear: The DIR911T with IntelliClear variable speed control is in a class by itself!
