The LCD B8 Model

$780.00

 

Edic-mini LCD is a new series of digital audio recorder (DAR). Having small size traditionally, the model features the following:

  • three-line LCD indicator;

  • joystick to control the DAR;

  • dynamic range, extended by 8 times (16 bit codec, and 18 bit when using an external microphone);

  • signal/noise ratio improved by 12 dB;

  • extended 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.

Voice recorders of the Edic-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 DAR is able to function within a wide range of temperatures, under strong vibration and dustiness.
For the user's convenience while operating the DAR, 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.

DAR operation features
The DAR records either in the sequential messages mode (one by one, the number of messages is limited only by the DAR memory) or in the cycle buffer mode (i.e. cyclically). The DAR can provide some memory size to the cycle buffer. As soon as the provided memory space comes to the end, the DAR 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 DAR 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 DAR for message recording, as well as a flash-disc at the same time, to store and transfer data of any format.

B8 model
B8 model is produced in a plastic case.
Dimensions: 59x28x9 mm, weight: 20g. Battery: CR2450.
Maximum record duration: 1120 minutes.
Continuous operation duration:

  • in Record mode: up to 250 hours;

  • in Playback mode: up to 50 hours;

  • in Standby mode: 2 years;

  • in VAS Standby mode: 2500 hours.

B8 model of DAR uses accessories of type 3.
 

DAR Record Quality
Edic-mini LCD DAR has several rates of voice compression which enables the user to make records of different quality and to compromise the record quality and duration.
The DAR provides for eight user settings for record parameters (profiles).
 

0 Extra high sample rate 16 kHz, linear (without compression), 256 Kbit/s k=16
1 Super high sample rate 16 kHz, logarithmic compression (16 LOG), 128 Kbit/s k=8
2 Normal sample rate 8 kHz, logarithmic compression (16 LOG), 64 Kbit/s k=4
3 Medium sample rate 8 kHz, modified 4-bit ADPCM, 32 Kbit/s k=2
4 Extra high VAS sample rate 16 kHz, linear (without compression), VAS, 256 Kbit/s k=16*
5 Super high VAS sample rate 16 kHz, logarithmic compression (16 LOG), VAS, 128 Kbit/s k=8*
6 Normal VAS sample rate 8 kHz, logarithmic compression (16 LOG), VAS, 64 Kbit/s k=4*
7 Medium VAS sample rate 16 kHz, modified 4-bit ADPCM, VAS, 32 Kbit/s k=2*

Software
The supplied USB adapter provides high-speed data exchange between the DAR 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 DAR parameters and to control admission to the DAR functions. Besides, with the software you may set admission levels to the DAR functions from joystick. The admission levels prevent data (or DAR settings) damage by unauthorized people.
The software features a user-friendly interface; no special skills are required to connect the DAR.

Glossary

Antialiasing filter A low-frequency filter, which is connected before the analogue input of the analogue-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 analogue 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.
