Samson AWXm Wind Instrument system offers the latest in Samson wireless technology by pairing the innovative ATX clip-on transmitter with the portable AR99m micro receiver. Unlock the entire stage with a frequency-agile wireless system that can fit in any gig bag. Relay Your Sound The ATX wireless transmitter' s inconspicuous design enables easy mounting while providing a gentle but secure clip-on connection to the bell of the instrument. Supporting up to eight hours of rechargeable, cable-free battery life, the ATX transmitter is the perfect compliment to the bell of your instrument. Mic How You' d Like Capture 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. Able to handle high sound pressure levels (SPL) of up to 125dB, the HM60 is well suited for close miking brass and woodwind instruments. The super cardioid polar pattern provides excellent isolation of the instrument while reducing pickup of unwanted ambient sounds. The unique 3-point halo isolation mount minimizes mechanical vibrations and key click noises. Multifunctional, One Compact Design The AR99m micro receiver puts an emphasis on functionality and versatility. With a 300' operating range and three output connections (1/4 , 1/8 , and XLR) the AR99m offers more compatibility while being a fraction of the size of other receivers. Ensure maximum wireless clarity anywhere by scanning the 100 available channels with a simple touch of a button; the AR99m analyzes and selects the clearest channel for your area. Turn the AR99m into a dual channel system by connecting a Samson XPD Series USB Digital Wireless System (sold separately) or conveniently charge the ATX transmitter with the receiver' s USB port.
