Lynx Micro System Integral G4 Helmets
Overview
| The Integral Helmet G4 is the latest digital Active Noise Reduction (ANR) version of the Micro System helmet which also includes a digital Voice Controlled Microphone (VCM). The helmet is specifically designed lor use in high noise environments and provides both head protection and streamlined fu1l face head protection. The helmet includes an ear-cup detensioner mechanism which reduces the ear-seal pressure when fitting and removing the helmet. This feature makes the helmet very easy to use wtIi1st ensuring optimum noise attenuation and comfort. The helmet ear-cups are also fully adjustable in lour axis 10 accommodate different head Sizes and head shapes and may be locked in position The helmet microphone is protected from wind noise inside the helmet chin guard and is positioned using a control on the piece of the helmet. This control allows the microphone to be moved out of the way during fitting and removal of the helmet and provides fine adjustment in use. The helmet shell is manufactured from carbon composite with a Polystyrene/Memory foam comfort liner . Other features include a quick release and quick adjust chin strap and clear or tinted visors. The digital ANR electronics monitor the level or background noise inside the ear-cups and generate an equal volume of anti-noise which is opposite in phase; this effectively reduces the amount of low frequency background noise inside the ear-cops. The ANR function can be switched on or off using a selector switch Ofl the nght hand side of the helmet Wlefl the ANR function is switched off. the helmet works as a normal Passive Noise Reduction (PNR) helmet. The VCM electronics monitor the helmet and disable the microphone when no voice signal is present. The microphone is re-enabled instantly when the VCM system detects speech. The VCM system uses digital technology to differentiate between speech and background noise/wind noise and adjusts automatically to changes in noise level. The VCM function can be switched on or off using a selector switch on the left-hand side of the helmet. When the VCM funclion is switched off, the helmet microphone remains active continuously. Each helmet contains an intercom circuit and a rechargeable battery. Connecting two or more helmets together forms an intercom providing communication for a minimum of fifty hours. The helmet includes digital power management which protects the battery by pulling the helmet into a low power mode when no helmet activity is detected. In addition, a switch is provided on the helmet to disable the battery if the helmet is only used with a Powered Radio Interface and the battery function is not required. Each helmet battery can be recharged up to one thousand times, and does not suffer from Memory effect. Micro System helmets can be connected to a radio via a range of interface units and are fully compatible with all available radio transceivers. |
