Voice recorders of the Profi-mini LCD series are professional devices intended for making high quality record of voice messages into the built-in flash memory. You can playback recorded messages using the earphone and save them into your PC as standard sound files.
Voice recorders are of extremely small size and weight, have a long record duration (varies with the model - up to 600 hours) and autonomy operation (up to 1000 hours), a wide dynamic range and a highly sensitive built-in microphone. Having no moving parts, the DVR is able to function within a wide range of temperatures, under strong vibration and dustiness.
For the user's convenience while operating the DVR, there is a push-button manipulator (joystick) and a liquid-crystal display to indicate all the information needed, including a built-in clock / a real-time timer.

DVR operation features

The DVR records either in the sequential messages mode (one by one, the number of messages is limited only by the DVR memory) or in the cycle buffer mode (i.e. cyclically). The DVR can provide some memory size to the cycle buffer. As soon as the provided memory space comes to the end, the DVR will start recording into the record beginning (i.e. deleting the previously recorded data). Therefore, the cycle mode is convenient if you want to have fresh information for a certain period.
The DVR has a Voice Activating System (VAS) which effectively compresses pauses in messages, therefore increasing the actual record duration. Activating VAS allows the user to save memory in pauses; but the data about time intervals is stored (and can be restored at further file processing with the software supplied).
You may use your DVR for message recording, as well as a flash-disc at the same time, to store and transfer data of any format.

Software

The supplied USB adapter provides high-speed data exchange between the DVR and PC (1.5 Mb). The software supplied on the CD makes it possible to save the recorded messages as standard sound files, to set the DVR parameters and to control admission to the DVR functions. Besides, with the software you may set admission levels to the DVR functions from joystick. The admission levels prevent data (or DVR settings) damage by unauthorized people.
The software features a user-friendly interface; no special skills are required to connect the DVR.
