Samson AirLine 99m AH9/DE10x - Dual-Headset UHF Wireless System (K-Band 470–494 MHz)

Samson AirLine 99m AH9/DE10x - Dual-Headset UHF Wireless System (K-Band 470–494 MHz)

The Samson AirLine 99m Double Earset System (AH9/DE10x) is a professional wireless microphone system designed for vocal and vocal on the go. It integrates the AH9 micro transmitter directly into the DE10x double earset , completely eliminating beltpacks and cables. Its AR99m desktop receiver with True RF Diversity operates in UHF with 100 channels within 24 MHz and offers ultra-fast setup with one-touch scan and IR sync . The K band (470–494 MHz) guarantees professional compatibility in multiple scenarios, and its rechargeable design with up to 8 hours of battery life allows for long sessions with complete freedom of movement and a range of up to 100 m line of sight.

Main features

• DE10x dual-ear headband with 3mm condenser capsule, omnidirectional pattern, 20Hz–20kHz response and IP65 protection against sweat and dust.
• AH9 micro transmitter integrated into the headband: without belt pack, with magnetic charging connector, gain control and mute button.
• Up to 8 hours of battery life per charge (built-in 3.6V/500mAh Li-ion battery).
• AR99m receiver with True RF Diversity , one-touch channel scanning, 100 channels and balanced XLR, 1/4" and 1/8" outputs .
• K band (470–494 MHz) with up to 8 simultaneous systems per band (depending on regional regulations).
• System audio quality : 50 Hz–15 kHz, >100 dB dynamic range and SNR >95 dB.
• Approximate range of 100 m (300 ft) line of sight.
• USB port on the receiver to charge the AH9 or add a second Samson XPD system and turn it into a dual receiver.

Product benefits

• Complete mobility : the transmitter is built into the headset itself; no cables or beltpacks to get in the way in classes, lectures, or on stage.

• Moisture Resistance : The DE10x microphone features a moisture-proof coating and IP65 rating for intensive use (fitness, theater, outdoors).
• Easy setup and operation : auto-scan, IR sync, and direct volume, gain, and mute controls.
• Versatile connectivity : balanced and unbalanced outputs for mixing consoles, active speakers, recorders or cameras.

Use cases

• Trainers and teachers : clear voice projection in classrooms and auditoriums without restricting movement.
• Fitness and dance monitors : lightweight, secure, sweat-resistant design for high-intensity sessions.
• Theatre, worship and events : visual discretion, stable support and intelligible audio.
• Presenters and speakers : hands-free with stable coverage for trade shows, keynotes, and streaming.

Frequently Asked Questions

• How many systems can I use at once? Up to 8 systems per band, subject to regulations and RF environment.
• What real-world range can I expect? Up to 100 m line-of-sight; walls, metal structures, and interference may reduce this range.
• Is it sweat-proof or outdoor? Yes. The DE10x is IP65 and moisture-proof, making it ideal for fitness and intensive use.
• What outputs does the receiver include? Balanced XLR and unbalanced 1/4" / 1/8" for integration into any system.
• Can it be charged from the receiver itself? Yes. The AR99m supplies 5V/200mA via USB to charge the AH9 using the included magnetic cable.
• Does it comply with frequency regulations? Availability of the K band (470–494 MHz) varies by country. Always check local regulations before operating.

Connectivity and integration

The AR99m offers XLR (balanced, +9 dBu/240 Ω) and 1/4" and 1/8" jack (unbalanced, +14 dBu/810 Ω) outputs, with fold-down 1/4-wave antennas for transport. In addition to IR sync and auto scan , the USB port allows the transmitter to be charged or an XPD series USB receiver to be added for dual-band operation.
