AirLine Fitness – Performance Headset System The Samson Airline 77 NO BODYPACK NEEDED combines the CR77 Receiver with Samson s classic Airline with built-in transmitter on the headsets. Breakthrough microcircuitry allows the AH1 to operate on a tiny triple-A battery with 14-hours of life. Plus, AirLine transmitters give you great sound and reliable wireless reception over long ranges, wherever you use it. And UHF (Ultra High Frequency) means your wireless system is operating on a much clearer frequency band with less interference.

This true-diversity half-rack unit with PLL frequency control is the heart of all Concert 77 wireless systems. Rugged, durable and crystal clear with incredible range. Diversity reception means no dropouts

Although there are two headsets, they cannot be used at the same time. In order to use two wireless microphones at the same time, you must have two different receivers on two different frequencies. This system is a bundle that uses two headsets to reduce wear and tear on each headset. Team-teaching or using both headsets simultaneously is not possible with this bundle. There is no mute button.
