The Compak Beltpack Transmitter and Monarch Headset Kit from Eartec includes a Compak beltpack transmitter and a Monarch microphone headset. It can be used to add additional users (up to 8) to an existing Comstar XT full duplex wireless system.
Designed for those who want COMSTAR hands-free communication but prefer lighter headsets, Eartec has fashioned the COMPAK Full Duplex Beltpack to function as a transceiver which can be attached to your belt or jacket by means of a spring-loaded clip. The COMPAK features a lightweight form-factor of 2.5 oz—battery included—as well an ergonomic shape that conforms to the contours of the human body. Its silicone-sealed mute switch allows you to cut the microphone gain, while a volume control gives you five different gradients of loudness. The transceiver itself is capable of a 400 yd communication range, all the while utilising a transmission power of less than 10mW, meaning no FCC licence is required to utilise this unit.
The Eartec Monarch Headset for Compak Beltpack is a lightweight headset manufactured with PBT, a material used for rough industrial environments. It features a slender backband that offers a unisex fit and is suitable for use at home, on the floor of a TV studio, or inside the cab of a tower crane. This Headset is compatible with almost all communication devices including existing wireless systems, transceivers, and hard-wired intercom.
