EDIC-mini Ray+ A105

Edic-mini Ray+ A105 is a professional voice recorder 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.
