3M Peltor System Control Unit

3M Peltor Tactical Modular Audio System (TMAS)


Communications Integration

  • Single, DUAL, and Multi COMMS configurable
    • Up to 3 Physical Communication Connections
    • Up to 6 two-way audio streams
  • Single Channel Radio, Multi-Channel Radio, and ICS Connectivity
  • Bluetooth® cell-phone connection capable (selected models only)


Audio Management

The SCU can handle multiple radios, with multiple channels. In such scenarios, the user is able to select one of three preset sound profiles:


  • Mix: Radio communication(s) are heard equally in both left and right ear.
  • Split: Radio communications will be spilt between the left and right ears.
  • Surround: The radio communications will be perceived as it is coming from different directions (10 o’clock or 2 o’clock) depending on which channel the radio is transmitted from.


Human-Machine Interface (HMI)

The SCU is designed to be integrated into the operator`s mission set of equipment

Wired or Wireless Headset Connection

In addition to an optional wired connection, TMAS lets you experience a secure, reliable cable-free connection between the SCU and headsets (both in-ear or overthe-ear). The SCU features proprietary automatic conflict resolution, which allows multiple users cordless communications in close proximity.


Near Field Magnetic Induction (NFMI)

Near Field Magnetic Induction is a short range, digital, wireless physical layer that communicates by coupling a tight, low power, non-propagating magnetic field between devices. The range is approximately 50 cm (20 in). The steep degradation of NFMI signal strength as a function of distance increases privacy and reduces issues with interference compared to traditional wireless technology. Spectral interference is reduced by a “channel hopping” algorithm incorporated into the TMAS suite.



Wireless Remote Switch

The SCU can be remotely operated via the RCU. Besides using the RCU as a PTT, it can also be used to adjust the volume level of the environmental listening or radio. Designed to be mounted on a picatinny rail, it can also placed elsewhere (i.e. steering wheel, second body location).
