The AirLine 99m Micro HUF Wireless System from Samson takes the concept of wireless technology to a new level with frequency agile transmitters and micro receiver, providing a completely “hassle-free” user experience. Featuring miniaturized circuitry and an internal, rechargeable battery the AH9 can operate for up to 8 hours on a single charge.This version of the AirLine 99m System combines an AH9 headset transmitter with a Samson Qe Fitness headset microphone. 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.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.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 connections (XLR,1/4” and 1/8”). An included USB port can be used to charge the AH9 transmitter or integrate a Samson XPD Series wireless system (sold separately) to make it a dual-receiver.ApplicationsLive PerformanceFitnessDJFeaturesAirLine 99m AH9 Fitness Headset Wireless System:Frequency-agile UHF wireless system100 operating channels across 24MHz bandwidthUp to 8 simultaneous systems per frequency band (region dependent)AH9 Wireless Micro Transmitter:Micro transmitter mounted directly to a double ear headset (no beltpack or cable required)Water/sweat-resistant Qe headset microphone with condenser capsuleUp to eight hours of battery life using built-in rechargeable lithium-ion batterySealed gold contact charging connectorLow battery LED indicator300' operating range (line-of-sight)Variable Gain control1-touch MuteFour windscreens includedAR99m Wireless Micro Receiver:True RF Diversity micro receiver design minimizes dropoutsSet button scans/selects optimal channel optionsIR sync wirelessly matches transmitter to receiver frequencyTone key prevents unwanted noise when transmitter is off or out of rangeChannel and Ready/IR/Peak LED displaysBalanced XLR, unbalanced 1/4" and unbalanced 1/8" outputsUSB port for adding a Samson XPD Series wireless system, AH9 transmitter or phone chargingRotary volume knob with integral power switch1/4-wave antennasSpecificationsAirLine 99m AH9 Fitness Headset Wireless System:Working Range: 300' (100 m)Audio Frequency Response: 50 Hz–15 kHzT.H.D.
