Miniature EM Digital Voice Recorders Tiny digital voice recorder (DVR) is intended for professional recording voice messages into flash memory. The DVR features very low power consumption, wide frequency range (100- 10000Hz), wide dynamic range and a highly sensitive built-in microphone. A built-in real time clock and a calendar are provided, as well as the mode of start-up by timer. Due to the absence of moving parts, the DVR functions in a wide temperature range, under vibration and dusty conditions.

B22 is the smallest model in the EM Digital Voice Recorders Tiny family: its size is only 6x25x31, but nevertheless it has extensive characteristics, providing up to 300 hours of recording at the sample rate of 8 kHz and 2 bit ADPCM compression.

The recorder is powered by a lithium battery.The DVR can be connected to PC via USB port with the supplied cable.
The supplied software, working under Windows 2000/XP OS, makes it possible:

• to save the recorded messages as standard sound files
• to set the DVR parameters
• to use the DVR as a flash-disc of 128-2048 MB, depending on a model, as well as to store and transfer files.
• There is an opportunity to update the DVR firmware using the software.

• The DVR has a Voice Activating System (VAS) which effectively compresses pauses in messages, therefore increasing the actual record time. Using this system saves memory during pauses, but the time intervals remain. When downloading records to PC, the pause length can be either restored (as silence) or passed depending on the settings made.
• The DVR operation modes are indicated with the LED indicator.
• The DVR is operated with a push-button.
• The DVR can act as a flash-disc, which enables storing and transferring any data on it.
• The DVR can be used simultaneously for both recording messages and as a flash-disc, with the distribution of memory space for message recording and flash-disc being set by the user.
• The DVR makes it possible to record by both daily timer (time of recording start and stop is set) and once timer (date and time of recording start and stop is set).
• To secure the data, a password may be set in the DVR, which prevents another user from unauthorized access to the DVR content and settings.
• Every record made with the DVR is marked with the recording start time and date, and has a digital signature to define the DVR, which was used to make the record, and possible modification of the record file.
• The DVR software provides a multilingual support.
