❯ MGT 11 Octopus | Multichannel Digital Audio Wired System
Room Monitoring Surveillance System


The MGT 11 Octopus device is a state-of-the-art digital four-channel wired microphone system designed for ambient surveillance. It comes equipped with a USB recorder and top-notch encryption capabilities.

The system is comprised of a master device, known as the MGT 11-RX, and four Microphone Devices, identified as MGT 11-TX, which are connected via a twisted pair cable.

The digital audio is sampled at 16-bit 16KHz without any compression to preserve all sound quality.

We conducted tests on communication between a master and a single TX using a basic telephone twisted pair cable in an open space covering up to 400 meters.

_Features:

  • Very compact size;
  • Superior audio quality;
  • Low noise audio path;
  • High quality Knowles MEMS microphone;
  • Two microphones for each Transmitter remotely selectable;
  • AGC System.
