SAMSON Airline 77 AH7 Fitness Wireless System

SAMSON AirLine 77 AH7 Fitness Wireless System (Band K)

Samson AirLine 77 AH7 Fitness is a revolutionary solution for fitness instructors, aerobics coaches, and dancers. This system eliminates the biggest inconvenience – the cable connecting the microphone to the belt-pack transmitter. Instead, the compact AH7 micro-transmitter is mounted directly on the headset. This provides complete freedom of movement.

The included Qe condenser microphone is specifically designed for intensive physical activity: its capsule is resistant to moisture and sweat. The bi-directional microphone characteristic effectively suppresses background noise in the hall and reduces the risk of feedback, capturing sound precisely from the front.

The system's CR77 receiver uses "True Diversity" technology with PLL frequency control, ensuring a stable signal even with active movement up to 90 meters away. The transmitter operates with one AAA battery for up to 8 hours.

Note: This version operates on a fixed Band K frequency channel.
