Hear It Right The First Time. Assure your team’s power to dominate the situation by hearing all communication the first time.

SIGTRONICS is the industry standard of excellence in high noise aircraft intercom systems since 1974. We applied the same advanced technology in the design of our intercom systems for tactical use. Our products are designed and assembled in the U.S.A. to insures the highest quality and durability. Sigtronics’ comprehensive customer support program provides our clients with a dedicated 800 line and web site for technical support, installation, and radio interface information.

INTERCOMMUNICATION: Our voice activated intercom systems provide convenient “hands free” communication. This feature improves safety by permitting the vehicle operator to communicate without diverting attention away from traffic surveillance. Use of a Sigtronics intercom also saves time by enabling the officer to brief the crew in route.

HEARING PROTECTION: Headsets reduce noise levels to protect hearing and to ensure clear communication with all personnel. Our headsets are light-weight, comfortable, and have noise-canceling electret microphones designed for superb voice fidelity and noise rejection.

RADIO INTERFACE: Sigtronics’ intercom systems interface to all mobile radios, and with our MRIM-2, to cellular telephones. This allows communication (both transmit and receive) to be heard through each headset position. Radio transmitting can be done from two or more positions. The crew’s intercommunication is not transmitted over the radio. To transmit over the radio, a radio push-to-talk switch is activated, and only that person’s voice will be heard over the air.
