All of the AirLine transmitters operate on inexpensive and lightweight AAA batteries that offer 14 hours of operation on a single battery.
The core of the receiver system is the CR77 true-diversity half-rack UHF receiver. It works flawlessly with all AirLine UHF transmitters. Featuring a front panel display with large multi-segment audio level and RF level LED meters, and a large rotary volume knob that allows easy adjustment of audio output, the CR77 takes all of the guesswork out making your wireless system perform.
Its 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 unbalanced 1/4-inch outputs allowing flexible connection options. In addition, two CR77 receivers can be rackmounted together in a single space rack adapter available as an added accessory.
