Description
The MKE-230-2 microphone is designed to record conversations and is available in several versions for use in various conditions:
Version 1 – The microphone is designed to record a dialogue between two people (client and operator) located opposite each other. In this case, the recording is carried out in two separate channels in order to simplify the subsequent analysis. The microphone is suitable for collecting biometric personal data.
Version 2 – The microphone is intended for use in teleconferencing rooms. The microphone uses built-in noise reduction systems, focused on the most clear voice transmission while suppressing extraneous noise.
Version 3 – The microphone is intended for use in video surveillance systems. An AGC system is built into the microphone, which allows you to get maximum information about the acoustic situation in the surrounding space. Also, this microphone has the ability to be powered from an external source with a voltage of 5-18V and an analog output for connecting to the audio input of the camera.
