Model & Key Features

MGT Pixel Nano 4G — GSM Audio Transmitter

Overview

The MGT Pixel Nano 4G is a compact remote audio listening system designed for modern cellular networks. It can operate as a standalone unit using an internal rechargeable Li-ion battery, supporting fast deployment where external power is not practical.

The system is engineered for installation in vehicles, offices and rooms. Where longer runtime is required, an external power option can be used to maintain continuous operation in fixed installations.

An onboard DSP stage improves intelligibility and helps maintain consistent audio quality in real-world environments.
