Peltor ComTac VI User Guide 

Fitting the speech microphone 

To maximize the performance of the speech microphone in noisy areas, position the microphone very close to your mouth (less than 3 mm or 1/8 inch).

NOTE: When used in high altitudes/aviation the surrounding pressure can be reduced rapidly and affect the microphone sensitivity, for example during helicopter ascent. If this occurs position the microphone closer and/or speak louder to increase the pressure on the microphone membrane.


Mission Audio Profile(s)

Ambient Listening Modes - Advanced 1-4, OFF or Classic (Mirrors COMTAC V/III)

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 in  five conditions. The MAP Profiles have been  designed with a variety of combat and combat  support operations in mind.

1: Observation Highest volume and widest frequency response to maximize hearing when the user is still (overwatch, hide, SLLS, etc).

2: Patrol High volume with reduced high frequencies to limit sounds such as footsteps on gravel, grass moving under feet, equipment moving on body.

 3: Conversation Maximizes the frequencies important for face-to-face communications while lowering the frequencies outside of the average speech band.

4: Comfort Low volume and narrow frequency response to be used when in noise for long periods of time (tactical vehicle, air transport) where environmental listening is not prioritized over communications and overall comfort.

5: Environmental listening off ComTac VI features the capability to turn the environmental listening function off, while not powering down the headset. This may be beneficial in high noise environments where the least amount of outside sound is desired to help with communications. 

Natural Interaction Behavior (NIB)

Double press the PTT button to toggle between the different modes, NIB PTT On - NIB Off - NIB Vox On. Press and hold the PTT button to transmit.

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. 

The NIB function is easy to use. Team members in proximity of each other (10 Meters) will be  automatically connected (when the NIB function is on) with full duplex communications.   

When the VOX mode is enabled, as the noise environment gets louder (levels 80db and above) hands free communications is enabled. PTT mode can also be set if the operator wants to manually control the voice transmit.

NIB frequency

For North America, Australia and New Zealand, the frequency for NIB is 915 MHz.

Earplug Mode 

Press and hold the + or – button for two seconds to power on the headset. The voice guide will confirm with “Power on”. Keep pressing the button until the voice confirm with ”Plug mode”.

In military environments, steady state noise levels of 120 dB or higher, are easily achieved. In steady-state high noise environments exceeding 103db, dual  hearing protection may be required not only for protection, but to maintain clear communications.  

In this mode, the headset volume is boosted by approx. 6 dB to help compensate for the additional attenuation provided by the ear plug.

Wireless input

Follow the user instruction for the 3M™ PELTOR™ TEPLOOP-* to set up the neckloop.

2. Enter the headset menu to adjust the wireless input and the sensitivity to correspond to the connected neckloop. Choose Off/Low/Medium/High.

3. Adjust the volume on the external radio if needed.

NOTE: The volume may differ depending on the distance between the headset and the neckloop 

Wired Input

Adjust the wired input and sensitivity to correspond to the wired device. Choose Low/High.


The balance setting adjusts the volume balance between the right and the left ear. 

There are seven level settings: 

Center,Left 1, Left 2, Max left, Max right, Right 2, Right 1.

Warning signals

The warning signal setting disables/enables the warning signals "low battery" and "automatic power off". 

When switched off, none of these warning signals will be heard.Automatic power off. The automatic power off setting disables/enables the automatic power off function.
