Rx775

Empower Your Operation

Clearer: Reduces noise up to 30dB
Faster: Filters voices in milliseconds

Overview

The Realix Rx775 is a flexible digital mobile radio designed for smooth communication across vehicles, motorcycles, and control rooms. It offers multiple control head options, smart connectivity, a modern UI, and AI noise cancellation for clear audio in noisy environments.

Key features

Flexible InstallationRealix Rx775 supports various setups with control head options—standard, single, or dual remote – using cables up to 40m (customizable up to 120m). Ideal for small vehicles, ambulances, trucks, buses, and desktop offices.
AI-Based Noise CancellationRealix Rx775 uses advanced AI technology to deliver clear audio by removing road noise, echoes, and nearby exhalation or howling sounds.
