Samson AirLine 99m AH9 Бежични сет K: 470 - 494 MHz

Wireless Headset System for Fitness Instructors and Active Performers

The Samson AirLine 99m AH9 is a frequency-agile UHF wireless headset system designed around the realities of fitness instruction, dance routines and high-energy stage work. Shipped as a complete water- and sweat-resistant bundle, the package pairs a Qe double-ear headset with an AH9 micro transmitter that clips straight onto the headset frame and a compact AR99m tabletop true-RF-diversity receiver. With the transmitter physically built into the headset, the wearer is left with no beltpack, no cable and nothing to bounce around during burpees, lunges or choreography.

Standout Features

What separates this set from typical beltpack-based kits is that the rechargeable transmitter is engineered to live on the headset itself, with sealed gold contact charging and a 3.6V 500 mAh lithium-ion cell. The AR99m receiver also exposes a dual-purpose USB type-A port that can either top up the AH9 transmitter or accept a Samson XPD Series wireless stick, turning one receiver into a dual setup without buying extra hardware.

Wireless Performance — Frequency-agile UHF with 100 channels

In busy studios or multi-room training complexes, finding a clean channel matters as much as the hardware itself. The AirLine 99m AH9 operates across 100 selectable channels in a 24 MHz bandwidth, with one-touch scan that analyses the RF environment and locks onto the clearest option. Pairing between headset and receiver is handled via infrared sync, while a tone key at 35 kHz suppresses unwanted noise when the transmitter is muted or out of range.

• System Type: UHF wireless with True RF Diversity — dropouts are reduced by receiving the signal on two independent antennas simultaneously.
• Channels: 100 operating channels / 24 MHz bandwidth — enough headroom to run up to eight simultaneous systems per frequency band.
• Auto Channel Selection: One-touch scan and IR sync — picks the cleanest frequency and pairs transmitter to receiver without manual menu diving.
• Line-of-sight operating range reaches 300 ft (~91 m), covering large studios, spin rooms and full gym floors with room to spare.

Headset and Transmitter — Water-resistant Qe capsule on the AH9 micro TX

The included Qe headset was conceived for environments where sweat and humidity are unavoidable. A waterproof condenser element sits on an adjustable stainless steel gooseneck that holds its position during head movement, while the lightweight double-ear frame keeps the fit stable over long sessions. The AH9 transmitter clips onto the headset frame, exposing one-touch mute, variable gain and a low-battery LED without breaking the cable-free design.

• Microphone Type: Sweat-resistant condenser, hypercardioid pickup — rejects off-axis room noise so coaching cues stay focused on the voice.
• Because the transmitter clips straight to the headset frame, performers carry no beltpack and avoid the snag points that typically show up during floor work.
• Battery: Built-in 3.6V 500 mAh rechargeable lithium-ion — sealed gold contact connector and up to 8 hours of continuous use per charge.

Receiver and Connectivity — Compact AR99m tabletop with flexible I/O

The AR99m receiver keeps the desktop footprint small enough to sit next to a laptop or mixer without dominating the tech booth. Three analogue outputs cover every common install scenario, while the front-panel rotary volume knob doubles as the power switch, and Channel plus Ready / IR / Peak LEDs make troubleshooting visible at a glance.

• Receiver Outputs: Balanced XLR, unbalanced 1/4" (6.35 mm) and 1/8" (3.5 mm) — works with mixers, powered speakers and portable PA gear out of the box.
• Dimensions & Weight: 110 mm x 95 mm x 39 mm / 192 g — light enough to slip into a gym bag between classes.
• Beyond the standard outputs, the dual-purpose USB type-A port either tops up the AH9 transmitter or accepts a Samson XPD Series wireless stick, effectively turning one receiver into a dual setup.

Who Is It For

The AirLine 99m AH9 is the right choice for fitness instructors, dance teachers, yoga and aerobics coaches, and live presenters who work without a sound engineer at their elbow. It suits anyone who has been let down by beltpack sag, cable tangles, or sweat-damaged capsule elements in regular studio sessions. Frequency-agile operation with 100 channels and up to eight concurrent systems per band also makes it a practical choice for multi-instructor studios and smaller houses of worship that commonly run 6–8 concurrent headset mics.
