The Ultra Electronics’ Graytronics Communications Systems are the most rugged audio intercom systems available. These systems, used by civil forces and in military applications, provide crystal clear audio and high performance under extreme conditions.

Intercoms used in an open cockpit environment suffer from background noise from engines and wind turbulence around the microphone. In order to overcome this noise we have designed our own speech processors, which modify the audio signal and allow only specified frequencies to pass through, thereby greatly reducing noise and increasing speech clarity.

The Graytronics communication and intercom systems enable multiple radios (secure and un-secure) to be integrated with crew intercoms and marine safety helmets. The systems also support audible engine alarms and activation of emergency alerts to base units.

A typical system comprises:

Master Control Box

Available with connections for radio operators, crew intercoms, one to six radios and alarm units (e.g. Engine Overheat, Threat Radar alert).
Illustrated is a single radio operator with access to two radios, five crew stations and input from boat alarms.

Radio Operator’s Control Box

Designed for use in an open cockpit environment, the control box allows radio operators to transmit, using remote or integral PTT, and receive signals on any of the radios fitted on board. It also allows them to conference with the rest of the crew or connect privately to the radio.

Crew Control Box (Non radio Operator)

Allows the user to adjust volume and talk with the rest of crew, using toggle or button PTT.

Headsets and Integrated Helmets Communication Systems

The waterproof moving coil loudspeakers and waterproof noise cancelling, pressure gradient, boom-microphones are integrated with ear defenders or marine safety helmets.

Options include:

• Integrated with PRR (Personal Role Radio)

• Waterproof loudhailer

• Waterproof loudspeaker

• Waterproof radio fist microphone

• Waterproof mobile telephone module

• Multi watch of two or more radios

• Emergency priority Tetra radio button

 All Graytronics systems are designed and built in-house to offer you maximum reliability under extreme operating conditions, with the minimum of maintenance.
