Samson AirLine 77 UHF TD Headset Wireless QE Microphone SystemSamson Airline 77 UHF Headset Wireless systems are an unbeatable combination.
The AirLine headset transmitter features the Samson Qe Fitness microphone element. The Qe headset is designed to go around the back of your head rather than over the top. This allows the transmitter to be attached directly to the headband, out of the way and completely unobtrusive, while being comfortable and secure during performances or exercise routines. No more wires crawling down your back from the headset, no more duct taping the mic to your favorite sax.
The CR77 true-diversity half-rack UHF receiver works flawlessly with all AirLine UHF transmitters. The CR77 receiver features a front panel display with large multi-segment audio level and RF level LED meters, and a large rotary volume knob allows easy adjustment of audio output. The new synthesized PLL frequency control circuitry keeps the signal locked and true while dual tuned molded antennas with LEDs monitor the true-diversity operation. The rear panel features balanced XLR and un-balanced 1/4-inch outputs allowing flexible connection options.
