MARVA, from Audiopack, is an NBC-hardened communications tool that coordinates a voice amplifier, lapel mic, and push-to-talk functions. The acronym MARVA stands for MAsk Radio Voice Amplifier.

Developed from Audiopack’s fire service communication device, the product was redesigned for tactical use with input from U.S. Special Forces. Taking into account the wide range of communications applications often necessary for tactical settings, MARVA was designed to transmit sound via a headset, throat mic, Invisio bone mic, or internal M-45 mask mic. If any headset fails, a backup lapel mic will take over communications duties.

Also, a dual operation version of MARVA operates two separate radios controlled by push-to-talk switches. This version allows a SWAT operations team leader to speak to a barricaded suspect and an entry team; his team on one radio and command on another; or two entry teams.

For special situations, MARVA can be operated while wearing a headset with a mic and speaker attached to a gas mask without wires penetrating protective gear. The entire system can be decontaminated.
