For the working horn player who wants the freedom to go wireless, the AirLine AWXm Wind Instrument System offers the latest in wireless technology by combining the innovative ATX clip-on transmitter with the portable AR99m micro-receiver. Small enough to fit in any gig bag, this system provides high-definition sound for wind instruments without the need for a beltpack or cables.Relay Your SoundThe unobtrusive design of the ATX wireless transmitter allows for easy mounting while providing a gentle but secure clip-on connection to the instrument's bell. With up to eight hours of rechargeable wireless battery life, the ATX transmitter is the perfect complement to your instrument's bell.Capture The Sound, Your WayCapture the sound of your instrument with the HM60 condenser microphone. Designed specifically for live performance, the microphone delivers the dynamic, natural sound of the instrument with a wide 20 Hz to 18 kHz frequency response. Capable of handling high sound pressure levels (SPLs) up to 125 dB, the HM60 is ideal for close-miking brass and woodwind instruments. The supercardioid polar pattern provides excellent isolation of the instrument while reducing the pickup of unwanted ambient noise. The unique 3-point halo isolation mount minimizes mechanical vibration and key click noise.Multifunctional, One Compact DesignThe AR99m micro-receiver is all about functionality and versatility. With a 300 ft range and three output connectors (1/4 inch, 1/8 inch and XLR), the AR99m offers more compatibility at a fraction of the size of other receivers. Ensure maximum wireless clarity anywhere by scanning the 100 available channels with a simple push of a button; the AR99m analyzes and selects the clearest channel for your area. Turn the AR99m into a two-channel system by connecting a Samson XPD Series USB Digital Wireless System (sold separately) or conveniently charge the ATX transmitter using the receiver's USB port.
