About RA108 Slimgard II
RA108 Slimgard II is a headset for use in high noise environments which is also compatible with close-fitting ballistic helmets. The headset attenuates higher-frequency ambient noise through Passive Noise Reduction (PNR), using the mass and volume of the headset. For lower frequencies it relies on supplementary attenuation from low-profile Active Noise Reduction (ANR) modules in each earcup.
RA108 Slimgard II Headset Technology
The mass and volume of the RA108 headset provides Passive Noise Reduction (PNR) effective at higher frequencies, while dedicated independent Active Noise Reduction (ANR) modules in each earshell deliver improved noise reduction at lower frequencies. ANR cancels unwanted signals by superimposing an identical signal in antiphase. Low-frequency noise within the earshell is detected, phase inverted and driven back via the earphone for effective cancellation.
RA108 Product Details
The close-fitting US Army PASGT helmet sets a difficult noise-reduction challenge, one that the RA108 Slimgard II headset overcomes thanks to its low-profile, internal, advanced Active Noise Reduction (ANR) modules and uniquely sculpted shape. The RA108 is compatible with PASGT-style helmets across the world, as well as a wide variety of weapons and equipment.
High noise attenuation
Passive and Active Noise Reduction (ANR) features protect the hearing of users exposed to high levels of continuous noise; the headset achieves high levels of noise attenuation.
Local sound awareness and talk-through
The user can enable talk-through to hear local environment sounds at safe levels (<85dBA) to maintain situational awareness of hazards or permit face-to-face conversations without defeating the hearing protection.
Battery powered talk-through
The talk-through feature is powered from the attached equipment or from a single AA sized battery when dismounted.
Fit and Comfort
The specially contoured earcups, ear cushions and adjustable neckband ensure enhanced comfort and fit, and reduced fatigue when used with a helmet.
We offer a wide range of headset variants compatible with all popular vehicle intercom systems, supporting live or switched microphone, press-to-talk (PTT) options and Active Noise Reduction (ANR).
The headset downlead is factory configured and terminated into the required connector with pinout and audio levels to match the attached equipment, enabling the headset to support mono or stereo communications. An optional press-to-talk (PTT) toggle switch is available, located in-line with the downlead cable. The boom microphone can be permanent live, or switched via the PTT. The headset Active Noise Reduction (ANR) and optional talk-through functions can be individually enabled/disabled via an optional control switch mounted on the earcup. The headset draws external power from the attached equipment for ANR and optional electronic talk-through features (18V to 28V DC supply required). Talk-through can also be optionally battery-powered, via an AA battery holder located on the neckband assembly.
We develop customisable solutions tailored specifically to exact end user applications for use in tracked, wheeled vehicles, dismounted and tactical applications.
