Overlook
The EDIC-Mini Tiny voice recorder is used
for professional voice recording onto a ash
media following by copying to a computer. Along
with extremely small size and weight, the recorder
has low power consumption, long recording time
(150-1200 hours depends on models, sample rate,
and methods of compression), and wide frequency
and dynamic range. An internal clock and
a calendar allow starting recording according
to time setting. As a recorder does not have
any moving parts, it can be used in challenging
environment: at wide temperature range, shaking,
and dustiness.
Using a provided USB cable, a voice recorder
is connected to a computer USB socket.
The supplied software, which operates under
OS Windows XP (SP3), Windows Vista, Windows7,
allows recording messages as common audio
les, programming recorder parameters, and using
a ash media for store and copying les, which
lengths vary from 128 Mb to 8 Gb, depending
on the model.
The rmware can be upgraded using a USB
interface.

Recorder voice activating system, VAS, allowing
effective compressing pauses in messages,
increases the length of a record while minimizing
memory usage. Time intervals stay the
same. If recording are copied to a PC, pause
lengths can be restored or skipped according
to program settings.
A light emitting diode, LED, signals according
to one of the operating modes. A recorder can
function in the ash media mode, allowing using
a recorder for data storage and exchange.
If needed, a recorder can be used simultaneously
as a ash media and as a voice recorder.
To prevent unauthorized access to a recorder and
stored data, password protection can be used.
In addition, along with its both time and date,
every record has a digital audio watermark.
It allows detecting which recorder made this record
and what changes the record underwent.
The rmware provides multi language support.
Depending on modications, the EDIC-Mini Tiny
voice recorders differ by:
• Control panel
• Power supply
• Stereo mode availability
• Space and type of memory

Specications
Signal-to-Noise: Ratio -64 dB;
Recording mode: Mono, Stereo, depending on the
model;
Compression algorithm: Without compression,
u-Law, ADPCM 2-and u-Law, ADPCM 2-and 4-bits;
Sampling Rate: 5.5, 8, 11, 16 or 22 kHz;
Frequency range: 100 Hz -10 kHz (depending on
settings);
Exchange rate with PC: up to 0,7 MB/sec.
Recording time of the audio recorder in differ-
ent modes
Index of the model 150h/300h/600h/1200h –
shows the maximum recording duration in hours –
sampling rate 8 k Hz, 2 bit ADPCM).
Tables 1-4 show recording time in different modes.
Different settings allow nding effective quality-
length ratio according to your demands. Sampling
rates affect a band of audio frequencies and
compression methods affect the space of memory
used while recording.
The best quality is achieved without compression;
however, it uses biggest amount of memory.
Every next mode in the sequence minimizes
memory space and makes quality worse: (u-Law),
4-bites ADPCM, and 2-bytes ADPCM.

Recorder’s battery life
Recorder’s battery life depends on the battery
in use, rechargeable battery (its charge level),
as well as on the record mode the Recorder
operates in. The approximate battery life is specied
in the instructions for an individual model.
Control panels of different recorders have various
design, it is described in a supplement of your
recorder manual.
Turn on your recorder using control panel, then
turn on recording. After you turn on recording,
a light emitting diode of your recorder performs ve
lashes, then recording starts. While recording, two
blinking sequences indicate a rechargeable battery
status and available memory.
The rst sequence indicates a rechargeable battery
status:
• one ash – fully charged,
• two ashes – enough for work,
• three ashes – should be charged.
The second blinking sequence indicates
the amount of memory available:
• one ash – 75-100%,
• two ashes -50-75%,
• three ashes – 25-50%
• four ashes – 1-25%.

To stop your recording, set the Stop switch in
a stop position. While stopping, LED blinks one
time. Duration of this ash can be some seconds
and depends on the available recorder memory
space.
After stopping, the recorder is in a stand-by
mode. In this mode, a recorder has low power
consumption and does not demand battery
exchange or rechargeable battery charging during
a long period of time. If there is not enough memory
size or a rechargeable battery is discharged while
recording, the recorder turns into a stand-by mode
automatically.
Playing Back Audio Recordings
To play your audio recordings, copy them
to a PC using the supplied software:
the RecManager program for Edic Tiny, which
is situated in the internal memory of the recorder.
Then play them using any program for music play
back, for example, Windows Media Player.
10
The Voice Activating System (VAS)
VAS, the voice activating system, allows
to essentially minimize (up to 100 times) memory
usage and power consumption. After you turned
on recording, your recorder starts getting audio
signals from its microphones. If the signals’ level
is higher than a threshold, the audio signals are
recorded into the recorder’s memory.
If the signals’ level becomes lower than
the threshold, after dened in settings period
of time, the voice recorder stops recording the audio
signals. Then the recorder registers the amount
of this silence period of time. After the audio signals
again exceed the threshold, the recording starts.
This succession is in a progress before you turn
off the recording.
The recorder’s LED signals the same way as when
recording without VAS: two consequences when
audio signals exceed the threshold, continuous
weak luminescence while silence.
While copying to a PC, you can decide to leave
or restore the pauses. If you decide to restore
the pauses, the record’s length is equal to the real
period of recording time. If you decide not to keep
the pauses, the recording consists of the recorded
parts that follow each other without any intervals.
