EDIC-mini Ray+ Series User manual

Short Operating Instructions for EDIC-mini Ray+ A105 recorders
Purpose:
The Edic-mini Ray+ series of professional voice recorders with an adaptive directional pattern and advanced features
including playback mode in the Recorder itself and OLED indicator. The use of 8 digital microphones with built-in 24-bit
audio codec provides maximum recording quality in the most difficult conditions, high acoustic sensitivity (up to 20
meters) and a wide dynamic range (24 bit). Availability of markers allows it to confirm the authenticity of the recording in
court. Recording is performed onto microSD card up to 256GB, which provides up to 1 year of continuous recording.
When recording in noisy, echoing premises at long distance it is impossible to achieve the desired recording quality using
conventional recorders with 1 or 2 microphones. The problem is that when recording at considerable distance the
recorder records not only the necessary signal, but also some external noise and the reflection of sound. This
interference increases quadratically depending on the distance from the sound source and at the distance of several
meters it really can drown out the desired signal. The only solution is to form a signal source direction pattern with
maximum drowning of signal from other directions.
To generate a direction pattern there are 8 microphones used in the Edic-mini Ray+ recorders forming so-called phased
array (similar to the one used in radars).
The application of 8 microphones also reduces the inherent noise of the microphones by 2.5 times. In the end, record
gain from the use of 8 microphones can be from 2 up to 6 (depending on the recording conditions) as compared to
recorder with one microphone.

*The parameter of autonomy is specified for Record Mode 8KHz/8 bit, in case of higher sampling rate or bitrate,
autonomy value is lower. Autonomy value considerably depends on the model of microSD in use and can vary to be
higher or lower. Average current consumption: in record mode (8kHz / 8bit) 2.7mA, in standby mode 2.5mkA without card
installed.

Operating the Recorder
1. Battery Charging
Before starting make sure the rechargeable battery is charged. Charge the battery if necessary.
Connect the supplied cable to the micro USB port of the Recorder, then connect it to the USB port of the PC, or to any
other USB charger with an output voltage of 5V and a current of at least 500 mA. During charging, the red LED will be on,
upon completion the green LED is on. Full charging takes 3-4 hours.
IMPORTANT: After the Recorder has been charged, remove the cable from the Recorder to avoid any possible
mechanical damage.

2. Preparing microSD Card
MicroSD card which is in the delivery set, doesn't require any preliminary preparation. It has a configuration text file
CONFIG_CARD24.INI containing Recorder's settings.
If a new memory card needs to be used, first make sure that the file system installed on the card is FAT32 or ExFat. Next,
install a new SD into the Recorder. The Recorder will generate a configuration file. With the first use of a new SD card a
long initialization is permissible (up to 1 minute).
3. Recording
To start recording press the REC button once for 1 second. The red LED flashes once and recording starts.
During recording, the LED flashes in 2 series, the number of flashes showing:
To stop recording, press the REC button once for 1 second. Red LED will be on to indicate recording has stopped.
DO NOT REMOVE MEMORY CARD DURING OPERATION OR WHILE THE LED IS ON
Failure to do so may damage the recorded file.
Note: Any number of flash series that is different from the above mentioned states for one of the following contingency
situations: 3 flashes - rechargeable battery is discharged, constant flashes of red LED indicate microSD card failure (full,
can not be read or not available).
4. Record Playback
The Recorder switches from standby mode to playback mode after a single short pressing of the PLAY button for 1
second. The Recorder start playing the last file recorded, indicating battery status with periodic green flashes. The
flashing pattern for assessing battery level is similar to the recording process. Recording can be played back through
headphones.
When the end of the current recording is reached, or after moving to the end of the recording using navigation functions,
playback stops, which is indicated by a rapid blinking of the green indicator. After that, if neither of the buttons id
pressed for 10 seconds, the Recorder goes to standby mode.
5. Configuring the Recorder. Editing configuration file through word processor
First make sure the Recorder is not in record or playback mode. Then remove the microSD card from the Recorder.
Using microsd-USB or SD-microSD connect the card to the PC, a smartphone, or tablet. Open the
CONFIG_CARD24.ini file using word processor, and start editing. To set the recording parameter, as well as to enable /
disable settings, select the corresponding value in the line with the parameter after the “=” symbol.
Editing configuration file from the Recorder
Use 'Mode' button to enter configuration mode. Navigation in configuration mode: 'Play' button - forward, 'Mode' button -
back, 'Rec' button - OK. After setting the necessary parameters, make sure to click Save and Close.
Configurator program for creating a configuration file
The supplied microSD card contains a folder with the corresponding software. There is Confiq_card24 prog program in
this folder. Also, this program is available for download from www.ts-market.com
● Run the Confiq_card24 prog program on your device, select the required settings and click the button 'Download new
settings'
● This program generates a new configuration file for your Recorder.
● Delete the old configuration file from the microSD card replacing it with the newly created one.
This program is designed as a java application, it uses any browser available on the device (your PC, tablet,
smartphone, etc.). The program operates offline (no internet connection needed).
Note: before removing the memory card, the Recorder should not be in one of the operating modes, all its indicators
being off. Failure to comply with this requirement may lead to an incorrect termination of the process operating the
memory card and to the loss of all information on it.
Detailed information on the operation, functions and programming of the Recorder is available in the full
operating instructions on the company's website www.ts-market.com.
