Digital Voice Recorder PLMB51120 ( Dimensions: 44 mm x 24 mm x 8 mm) is intended to record voice messages within frequency band 300-3400 Hz in flash memory. It can play back stored messages using an earphone or download the messages to a personal computer as standard sound files.

PLMB51120 has small overall dimensions and weight, long battery life, long record time 18,5 hours with enabled Voice Activation System (VAS)), has a high-sensitive built-in microphone (range up to 8 m) and wide dynamic range. Due to absence of moving parts the PLMB51120 is efficient in broad band of temperatures, in conditions of shaking and dust content. PLMB51120 is connected to a computer with a supplied adapter. The supplied software allows saving recorded messages as standard sound files in "wav" format with date/time stamp, to program PLMB51120's user interface, to use a PLMB51120 for storage and carry of any computer files.

Ideal for covert recording, this model will be supplied only in black colour at the moment!

 

Since PLMB51120 has no moving parts it can safely operate in a wide environmental range and without - being detected by any special equipment.

+ Voice Activation System
Digital voice recorder has Voice Activation System (VAS) which allows effective silence compression during voice recording and thus extending recording time.

+ Benefits of the used PCM compression
PCM compression format perfectly compresses any sound information, not only voice of a person as it’s made in other voice recorders. That is why Digital voice recorder provides excellent possibility to record any sounds and compress it according to your settings without specific distortions.

+ Cyclic and/or linear record modes, internal real time clock
Digital voice recorder can store recorded voice messages to cyclic and/or linear buffers (number and length of independent messages is restricted only by memory size). Any part of the internal memory can be assigned to the circular buffer. Each message is automatically date/time stamped by the built-in real-time clock.

+ Powerful navigation system
The Digital voice recorder provides the following possibilities of navigating while playing back voice messages: you can jump to the next/previous/last/first message, to the beginning/end of the current message, rewind/fast forward the current message with variable speed and erase the messages from the internal memory.

+ LED indication
Two built-in LEDs display the Digital voice recorder's mode and battery status.

+ Built-in and remote control
Two buttons control the Digital voice recorder. It can also be remotely controlled by two external inputs. All the functions of the buttons/external inputs as well as the LED modes can be completely reprogrammed with a computer using the included software package.

+ Hot switch of wide range of settings
The Digital voice recorder supports fast selection of up to 8 record/playback modes including: recording quality/density, mono/stereo mode (the setting of the stereomode is effective only for type S) and VAS settings, circular or linear recording as well as rewind/fast forward speed and playback volume.

+ PC interface
The Digital voice recorder can be connected to a PC through the standard LPT-port, switched to bi-directional mode, using the supplied adapter. Data transfer rate is about 150-200 kbod (depends on a computer).

+ Software possibilities
Original software package operates under Windows 9x/Me/NT/2000/XP. It allows to transfer voice and data messages between the Digital voice recorder and PC, save voice messages to PC's hard disk in standard format (for further replay and editing by any third party PC software), synchronize the Digital voice recorder and PC time and completely reconfigure the Digital voice recorder's user interface. The voice/data exchange between the Digital voice recorder and PC can be password protected.

+ Digital diskette mode
The Digital voice recorder can be used as a “digital diskette” to store and carry over any digital data files. You can use the Digital voice recorder in both modes (voice recording and data storage) simultaneously. A user can define the “digital diskette” size.
