• joystick to control the DVR;
• dynamic range, extended by 8 times (16 bit codec, and 18 bit when using an external microphone);
• signal/noise ratio improved by 12 dB;
• ended recording frequency band (100-6000 Hz), sample rate selection 4/8/16 kHz;
• lower current consumption: half in Recording mode, 5 times lower in Standby mode and 20 times lower in VAS;
• faster data exchange with the PC through the supplied USB adapter;
• timer for automatic scheduled recording;
• antialiasing program median filter available to improve recorded and played signal quality;
• firmware upgraded by the user;
• new, more functional software for PC.

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.

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.

Glossary:

Antialiasing filter
A low-frequency filter, which is connected before the analog input of the analog-to-digital converter. It is necessary to prevent possible distortions related to spectrum aliasing during the AD converting.

Dynamic range
The difference between levels of the loudest and quietest sounds, evaluated in decibels.

Signal/noise ratio
Determines the signal intensity relative to the background noise of data transfer channel, evaluated in decibels.

Sample rate
The rate of sampling at converting the analog signal into digital. It is evaluated in the number of samples per second or in hertz. For example, the sample rate of the CD system is 44.1kHz. The lower the sample rate value, the poorer the quality of the digital record, but smaller the record file size.
