This system is available in different frequencies.
The Samson AirLine 77 AH7 Fitness Headset system is a wireless microphone solution designed to meet the specific demands of fitness instructors and active performers. With the unique AH7 micro transmitter mounted to a sweat-resistant Qe fitness headset microphone, you can free yourself completely from cables and beltpacks for a truly exhilarating and motivating experience. This allows you to focus on your class or performance, and not have to worry about your audio.
Building upon the groundbreaking technology of the AirLine transmitter, the AH7 micro transmitter is mounted directly on the headset. This is unique when compared to traditional wireless systems that typically use a beltpack with a wire running from the microphone to the transmitter. The AH7 eliminates these extra components that would be especially cumbersome for a fitness instructor and puts everything you need neatly and comfortably around your head. And the transmitter operates for up to eight hours straight on a single AAA battery.
The AH7 Headset Transmitter is mounted to a lightweight, adjustable headset that fits comfortably around your ears and the back of your head, even through days teaching back-to-back classes for hours on end. The headset also features the Samson Qe condenser microphone, whose sweat-resistant capsule prevents corrosion from prolonged exposure to moisture. In addition, the mic's bidirectional pickup pattern reduces background noise, minimizes feedback problems and effectively rejects signals not originating directly in front of the mic capsule.
The CR77 True Diversity receiver provides reliable performance with up to 300' (90m) of wireless operation. Its half-rack housing is light enough to throw in your bag, or it can be permanently installed with a rackmount kit (sold separately). The rear panel features balanced XLR and unbalanced 1/4" outputs allowing flexible connection options.
