Overlook

Voice recorders of the Edic-mini Tiny (16) +
series are professional devices intended for
making high quality record of voice messages

into built-in ash memory. The recordings
can be further uploaded onto the PC.

These voice recorders feature really unique
characteristics (the world's smallest size, maximum

autonomy, high acoustic sensitivity etc).

The recorders are marketed as personal means
of documenting audio information providing
protection against fake records as well as

unauthorized access to records.

The EMPlus program located in the built-in memory

is used to operate the recorder. SoundProcessor

program is designed to process the transferred
records and to facilitate the conversion of records

to text. The programs operate under Windows XP
(SP2, SP3)/Vista/7/8.

Depending on the model, the recorder features
extremely small dimensions, weight and current

consumption, long record duration (from 300
hours at sampling rate 8 kHz), wide frequency and
dynamic range. The recorder features built-in clock

and calendar, and the option to start recording at

2

the preset time using timer. Due to the absence

of removable elements the recorder is operational
under wide temperature ranges when shaking or

dusted.

The LED indicates operating modes of the device

as well as its status.

The recorder is equipped with VAS enabling to
compress pauses efciently in messages therefore
saving considerably the recorder's memory. When

uploading records onto the PC the duration of
pauses can be restored in the form of silence or

deleted depending on the settings specied.

The recorder makes it possible to perform timer
recording: either daily (with record start and end

time specied) or once (with date and time of
record's start and end parameters specied).

To protect the recorder’s information and setting

there is the option to set user's password. Each

record performed by the recorder has a mark of
time and date supplied with “digital signature” to
identify the model of the recorder to have performed

the recording and the attempts to modify it.

3

Depending on the modication, recorders differ in:

• Power source (battery, built-in rechargeable
battery or battery + solar battery, external
power supply)

• Built-in memory capacity

• The option to quickly replace the memory

The user can upgrade the recorder's rmware via
USB port.

Recording Duration

Recording duration depends on the type and
quality of the battery in use, its charge level, and

the record mode specied. Estimated duration for
different modes is specied in Appendix 1.

Installing and replacing batteries

Before starting, install the supplied battery. The
LED ashes 3 times and it will be on for about 40
sec. Now the recorder is ready to start operating.
When installing, always observe polarity (marking

on the recorder's case corresponds to the one on

the battery). Incorrect installation of battery may

lead to malfunction, which is not covered by the

warranty repair.

Supplying power for E71 and E72

For recorders with external power supply connect

a DC voltage source (3.7- 6 V) to contact 1 (minus)

and 2 (plus) of the stub coming from the Recorder

(Contact 1 is highlighted in color). In case of a Li-

Pol battery being a voltage source, battery charge

can be provided by the current of 100mA using
the connection of contacts 2 and 3 (if the adapter

is connected to the recorder and the computer's

USB).

5

Start and Stop Recording

To start recording, set the Switch to «On». The
LED ashes ve times, and the recorder starts
recording. During recording, the LED is ashing,
the number of ashes indicating battery charge
level (1 ash indicates charge of 80-100%, 2
ashes - 20-80%, 3 ashes indicate charge of
0-20%, which means the battery must be replaced

or rechargeable battery charged) and free memory

capacity: 1 ash states for 100-76%, 2 ashes ­75-51% , 3 ashes - 50-26%, 4 ashes - 25 -1%.
The interval between the rst and second series of
ashes is approximately 4 seconds, and between
the second and rst is about 8 seconds.
Note that in battery recorders the rst series of
ashes shows battery charge at the time the

recorder has been activated and is not controlled

during recording.

To stop recording, shift the Switch to «Off» position.
The LED ashes once for 10-12 seconds and the
recorder stops recording.

Attention:

• Avoid using the recorder with nearly
discharged battery, otherwise it may turn
off at the wrong moment.

• The higher the record's sampling rate, the

more energy is consumed by the recorder.
At the frequency of 22 kHz the consumption
is twice higher than at 8 kHz, and for the
recorders with batteries the autonomy is
down by more than three times.

• Fast switching during recording
(On → Off → On) puts the tab which is

visible in the Sound Processor program.
Thus it is possible to mark the desired

parts of records and then quickly nd them.

• Fast switching when the recorder is off
(Off → On → Off) shows battery charge

level the and free memory capacity through

ashing of LED. For this indication, see

«Start and Stop Recording.»

Playing Back and Uploading to the PC

Use EMPlus program to play back and upload

records onto the PC as well as to congure your
recorder. SoundProcessor program is designed to

process the transferred records and to facilitate the

conversion of records to text.

Both programs including the instructions are in
the built-in memory of the recorder and operate

under Windows XP (SP2, SP3) / Vista/7/8. Newer

versions are always available on the website

http://www.ts-market.com

1. Connect USB adapter to the recorder,
then to the PC. Red and green LEDs are
briey on the adapter. Windows recognizes
a new removable drive. It is very important

to observe the connection sequence:

Recorder→USB adapter→PC

2. Run the EMPlus program from the
recognized removable drive. The content

of the recorder is on the left side of the

window. Select the desired record.

3. To play back select the record and press

the Play button at the bottom of the left

8

panel. To upload right click on the selected
record and choose «Copy to PC» from the
context menu. The record will be converted
to WAV to be displayed at the right panel.

You can also drag and drop the selected

record from the left panel to the right one.

• Do not disconnect the recorder while

performing any operations in the EMPlus
program. This can cause data corruption

(during such operations the recorder's LED
is ashing).

• When the recorder is connected to the PC,

recording is unavailable. If the recorder
is in record mode, recording stops after
connecting to USB port of the PC.

Observe disconnection order: rst disconnect
recorder from USB adapter, then USB adapter
from the PC.

Uploading from the B70 recorder

For the model Tiny + B70 slide the recorder's cover
with ash memory in the direction indicated by the
arrow and slide it onto the USB adapter of B70.
Then connect the adapter to the USB port of your
computer.

Records are uploaded from the Tiny +

B70 recorders with the help of Reader which
is included into delivery set. Unzip the folder
RMUsbDrv located in the recorder's memory.

If you have USB2.0 driver on your PC, remove
it using the RemoveOlddrivers.exe

program located in the folder RMUsbDrv (in case

you have Windows Vista/7/8, launch the program
as Administrator). Connect Reader to the PC. After

that it suggests installing the driver from the folder

RMUsbDrv through the «Found New Hardware
Wizard» window. Remove Flash memory of
the recorder and insert it into the Reader. Connect
Reader to the PC. Run EMPlus program. Select
connection type Adapter USB 2.0.

Setting Microphone Amplification for Tiny16+

The recorder provides the option to adjust

amplication of the microphone's signal (from
0 dB to +40 dB). Both xed amplication and
Automatic Gain Control can be set. AGC enables
it to automatically adjust amplication according to
the sound level. That makes it possible to perfectly
record very loud sounds and amplify silent ones.

Timers

The recorder has two timers: Daily and

Once. Timers enable recording to start
automatically, without user’s control.

1. When setting Once Timer you need to

specify the record’s start and end time

and date. For example, «start 31.12.2013
23:00 stop 03.01.2014 10:00» - with

these settings your recorder will record

from 23:00 on the 31st of December 2013
until 10:00 of January 3, 2014. However
while conguring you should take into

account the capabilities of your recorder,

i.e. whether it’s free memory is enough to
perform the operation. To check this see

11

«free memory « in EMPlus and continuous
operation time in Appendix 1.

2. When conguring Daily Timer you need
to set record's start and end time. For
example «start 09:20 stop 13:05» - with

these settings the recorder starts recording

every day at 9:20 and stops recording at
13:05. Recording will be carried out as long

as the recorder has free memory, enough

charge and as long as the timer is on.

3. You can use both timers simultaneously,

but you should take into account that
timer's operation times must not overlap or

intersect.

Timer recording by can be stopped by

shifting the recorder's switch to ON, then
again to OFF position.

If timer is on, you don't have to enable recording
using switch (don't forget to synchronize the
recorder's time with the PC time).

Voice Activation System (VAS)

Voice Activation System (VAS) can signicantly
(up to 100 times if properly congured)

reduce both memory consumption and

12

energy consumption from the power source.
The principle of VAS is as follows: after

the user starts recording, the recorder

starts tracing signal from the microphone.
If the signal is less than the one specied in settings
(VAS level), it is not the sound from the microphone

that is stored in memory, but only the time value

during which the threshold hasn't been exceeded.

When signal level exceeds the preset threshold,
recording of sound into memory starts. When the

signal from the microphone is less than the preset

threshold, after some time (VAS time) the recorder

stops recording sound into memory and only saves

silence duration. That continues until recording
stops.

In case of signal level exceeding the preset
threshold, indication while recording with VAS is

the same as during standard recording (two series

of ashes). In case of signal below threshold
(silence), there is constant faint glow of LED.
When uploading record onto the PC, you can

specify the operations with pauses: save them in

the le uploaded or not. If you save pauses, the

duration of the resulting record will correspond to
the actual one, and the fragments when the signal

was below threshold will be played back silent. If

13

the pauses are not saved, then the resulting record
will consist of recorded parts only (signal exceeds

the threshold). These parts will be played one after
another without interruption.

Configuring VAS

Voice Activation System (VAS) is congured

in the EMPlus program by changing two

parameters: VAS threshold level and VAS time.
VAS level can be adjusted from 0 to -55 dB. 0 dB

corresponds to very low sensitivity (the device
records only very loud sounds) and the value of

-55 dB to very high sensitivity (the slightest rustle

is enough for the recorder to start recording). The
best of VAS is achieved experimentally. You can
start by setting VAS level at - 20 dB (after you

have changed the settings, do not forget to press

the button «Apply changes to the Recorder»).

After disconnecting the recorder off the PC enable
recording and place it in the conditions similar
to the planned recording (for example, lecture

in a classroom). With the level of VAS properly
congured, after the desired signal, the recorder

switches to record mode which will be indicated

by a LED ashing. If desired signal stops, and the
VAS time is up, the recorder switches to Signal
Standby mode.

14

If in case of silence, the recorder does not go to
Signal Standby Mode and continues recording,
VAS level is to be changed to be closer to zero (if it
was -20 dB, now it should be set at -17 dB).

If when desired signal appears the recorder
does not go to Record Mode, the level of VAS

should be changed to be closer to -55 dB (if it

was - 20 dB, now you need to set it at - 25 dB).
VAS time is adjusted from 1 to 15 seconds. If you
set VAS time at 1 second, the record within the le

will be divided into many pieces with the pauses

in conversation for more than 1 second. If you set

15 seconds, after any knocking the recorder will

continue recording silence for 15 seconds. The
best of VAS is achieved experimentally, but for
most cases the value of 7 seconds is enough.
If VAS operates together with timers, you don't

have to enable recording as it starts automatically
with the timer, providing that you synchronized

the recorder's time with the time on the PC.

Circular Recording

The Recorder has the option of circular recording.
In the EMPlus program you can devote a part of

the recorder's memory (or the whole memory)

15

to circular recording. After there is no more free

memory, the recorder begins to record new data

over old ones. The volume of the memory specied

determines the duration of the resulting circular

record.

Charging and Battery Maintenance

The battery starts charging automatically when

you connect the recorder to the USB- port of
the computer. Full charging takes 3 hours (while
charging LED is ashing gradually with the interval
of 5 seconds). With maximum charging LED will
continuously and smoothly change its brightness.

The user can recharge the rechargeable battery

via power source with standard USB- output (5 V),

during which the LED is permanently on and one
can assess the process according to the charging

time only (3 hours).

Do not leave the rechargeable battery discharged.

Recharge it at least once a month, even if you

don't use the recorder . Failure of the battery due
to customer's fault is not covered by the warranty.

16

Recorder Settings

With the EMPlus program you can set all the

necessary parameters of the recorder, such as:

• Enabling and conguring timers

• Enabling and conguring VAS

• Enabling and conguring circular recording

• Recording quality adjustment

• Password protection of the recorder

• Synchronization of time and date of the
