Micro Wireless Design, Macro Wireless Performance The Samson AirLine 99m AH9 Fitness Headset system is a unique wireless microphone solution designed to meet the specific demands of fitness instructors and other active performers. Along with a water/sweat-resistant Qe headset microphone, this frequency-agile UHF wireless system combines the AH9 micro transmitter and AR99m micro receiver for a highly-portable, rechargeable setup that offers high-definition sound completely free of cables and beltpacks. AH9 Micro Transmitter While Samson revolutionized wireless with the original AirLine transmitter, the AH9 is the exciting next chapter to the story. Thanks to its micro design, the AH9 transmitter is mounted directly on the included Qe headset, completely eliminating beltpacks and cables from the setup (ideal for active performers). In addition to a 300' operating range, the AH9 offers easily accessible Gain and Mute controls, a battery life LED indicator, and an 8-hour rechargeable lithium-ion battery. AR99m Micro Receiver Offering frequency-agile UHF operation, the micro-sized True RF Diversity AR99m receiver provides 100 available channels to secure reliable wireless performance. The receiver provides easy setup with 1-touch scan which analyzes and selects the clearest operating channel, infrared set to pair the transmitter with the receiver, and versatile output connectors (XLR, 1/4", and 1/8"). A USB port on the AR99m receiver can be used to charge the AH9 transmitter or integrate a Samson XPD Series wireless system (sold separately) to make it a dual-receiver. Qe Headset Microphone The AirLine 99m AH9 Fitness Headset system includes a Qe headset microphone, specifically designed for fitness instructors and high-energy performers. The Qe features a lightweight, double ear headset design with an adjustable/removable strap for a more secure fit. At the end of an adjustable stainless steel metal gooseneck sits the condenser microphone, whose water/sweat-resistant capsule prevents corrosion from the prolonged exposure to moisture that is to be expected in a fitness setting. And with a bidirectional pickup pattern, the Qe's condenser capsule takes hold of stunning audio while reducing background noise, minimizing feedback problems and effectively rejecting signals not originating directly in front of the mic.
