Built for comfort and safety The Speakers used for all Pama Helmet headsets are no ordinary speakers the speaker itself is special providing a class leading frequency response power output and compact size. This results in a comfortable fit helmet speaker that provides an impressive bass response making for excellent stereo audio quality and clear and natural speech. The output power allows for loud music and speech through ear plugs and the helmet lining. The speaker can be fitted in a number of ways to best suit your helmet. The Velcro pad can be stuck to the helmet lining the speaker cover can velcored directly to the helmet lining the speaker and cover can be positioned behind the lining or the speaker alone can be positioned inside or behind the lining. Some helmets have recesses which the cover can be pressed in some have pockets to fit speakers. The microphone is critical to the performance of a helmet system it must only pick up speech directly in front and close to it. The potential high levels of background noise wind noise and vibration can make speech impossible if the microphone were to pick up these noises. The Pama microphone has been carefully designed to be virtually immune to vibration and virtually deaf to wind and background noises. The HM100t kit has a Flex boom microphone which is fix with a velcro disc into the inner side of the helmet with the microphone angled directly in front of the mouth. All connectors in the system are waterproof .
