Headsets Interface Unit

The picture shows an example of a communications solution centred on a Headset Interface Unit (HIU).


This solution is designed to be used by firearms teams and provides a modular system giving the ability to interchange different headsets and push-to-transmit switches to fulfil the different operational requirements.


The HIU features a PTT switch and volume control on the front of the unit, a socket mounted on the top for headsets and also a side mounted socket for the connection of remote PTT switches. Internally the unit has a Tone Generator that allows the PTT and also remote PTT's to generate marked tones over the network for silent operation.


For Dynamic Entry and Snipers a tactical headset or Genesis headset could be used, worn with a soft hat or ballistic helmet this provides a noise-cancelling microphone and receive earpiece.


If it is necessary to operate in a covert role then a combined microphone/inductor or neck-loop microphone/inductor is available. Used in conjunction with a covert wireless earpiece and torpedo PTT this provides a fully covert solution centred on the HIU.


HIU enhanced




Also available is our Enhanced Headset Interface Unit 2 (EHIU2). Integrated into the unit is a PTT with non-verbal "tones" and a Volume Control dial.


At the top of the unit is a latching HiRose along with a side mounted 2.5mm receive only socket for headsets and receive only earpieces. The EHIU2 also has the capability of using a remote wireless PTT function, giving the user further flexibility for crucial communication.




The Rugged Wireless PTT can be used with a Picatinny Rail mount, or as a wrist/weapon strap deployment option.
