Samson AirLine 77 AX1 UHF Handheld Wireless System delivers the first micro-technology transmitter in the industry. Samson AirLine 77 AX1 consists of an AX 1 handheld transmitter, a CR77 true-diversity half-rack UHF receiver and a Samson Q7 dynamic microphone. AX1 super-compact transmitter plugs directly into the XLR jack of the Q7, so small and light weight, you’ll hardly know it’s there. Q7 is the finest Neodymium handheld dynamic mic Samson makes. Airline transmitters operate on AAA batteries that offer 14-hours of operation on a single battery. CR77 receiver features a front panel display with large multi-segment Audio level and RF level LED meters, and a large rotary volume knob allowing easy adjustment of audio output. The rear panel features balanced XLR and un-balanced 1/4-inch outputs allowing flexible connection options. Two CR77 receivers can be rack mounted together in a single space rack adapter available as an added accessory. Samson AirLine 77 AX1 UHF Handheld Wireless System allows the user complete freedom.
