Active Noise Reduction, engineered for the cockpit.
Our ANR system for aviation headsets and helmets — supplied, fitted and supported by Mac Aero.
Overview
Our Active Noise Reduction (ANR) system delivers superior noise reduction and speech clarity for pilots, ensuring comfort and protection from high cockpit noise levels.
Compatible with Alpha Eagle and Alpha 900 helmets, it features independent volume controls, Bluetooth connectivity, and an auxiliary input with audio priority settings.
The system automatically switches between aircraft and battery power (2 × AA backup) and connects via 6-Pin (Redel) or 8-Pin (Lemo) plugs, offering reliable, high-performance communication in demanding aviation environments.

- Customisable Audio Prioritisation. Choose between “mute”, “mix”, or “off” modes to control how intercom and auxiliary inputs interact.
- Flexible Power Options. Operates from aircraft power or two AA batteries (up to 45 hours of use).
