Audio Control Unit Communication Hub


The ACU is an intelligent interface, supporting coherent communications in land, sea and air environments.

As a world leading supplier of communications interfaces, the company recognises the unique and challenging conditions in which the modern war fighter has to operate, and understands the need to provide a reliable and simple communications capability.
The ACU three port communication hub can support up to two radios plus intercom providing continuous communications as soldiers conduct operations.

Situational Awareness (SA) is a key attribute of the ACU.  It is achieved via a suite of headsets to cover the spectrum of operating environments, both low and high noise.  For high noise environments, where hearing protection is required and SA is vital, ACU can be used in-conjunction with the In-The-Ear (ITE) Hearing Protection headset.  The ACU maintains microphone functionality when no headset is attached.
