Hear the difference.3M™ PELTOR™ ComTac™ VI has new omni-directional microphones, high fidelity speakers, and a new digital signal processor that helps improve the overall sound quality of the headset.The environmental listening feature, also known as “talk-through” is a means of allowing safe audio sounds to bypass the individual hearing protection electronically while still helping protect against harmful noises. This is accomplished with 3M’s proprietary digital audio circuit integrated into the headset.A microphone receives the sounds outside of the headset and transmits them to a speaker inside of the headset. The level-dependent digital audio circuit senses noise levels above the desired threshold and compresses them to a safe decibel level or amplifies weak sounds to an audible level.Sound detection.Sound identification.Sound localization.Speech communications.All important components of auditorysituational awareness, impactingWarfighter efficiency and safety.The 3M™ PELTOR™ ComTac™ VI offers a new way to adjust the auditory settings of your headset for your mission. Traditionally, a headset has a set frequency response, and the operator can only increase or decrease the volume. The MAP function provides new advanced ambient listening modes that allow access to a variety of gain settings, but with frequency shaping, to enhance auditory performance infive conditions. The MAP Profiles have been designed with a variety of combat and combat support operations in mind.NIB enables short-range, headset-to-headset communication in high noise environments, without the use of an external communications radio. The NIB function allows for 4 team members to speak simultaneously, and over 60 people within a 10 meter radius to listen at any given time. Audio transmit is activated by either a voice activated switch (VOX) for hands free operations or by push-to-talk. The VOX switch is adaptive, meaning the threshold to activate will adjust automatically to the noise environment. To help reduce user burden, a tactile button has been added to the left ear cup that allows the user to easily turn on or off the function / and switch from VOX to PTT settings.S13
