The SW7AVSHX is an Airline 77 wireless handheld microphone system with an AX1 plug-on transmitter. AirLine 77 features the first micro-technology transmitters in the industry. Traditional wireless systems consist of beltpacks and wires that hinder the performer. With AirLine, you get a true wireless system because there are no beltpacks and no cables, allowing the user complete freedom.

The compact AX1 Handheld UHF Transmitter allows a user to convert any dynamic microphone into a wireless mic. It’s as simple as plugging the standard female XLR connector of the AX1 into any standard wired dynamic microphone, making it easier than ever to go wireless. And because it’s so small and lightweight, the AX1 feels like a natural part of the microphone.

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 unbalanced 1/4-inch outputs allowing flexible connection options. Two CR77 receivers can be rackmounted together in a single space rack adapter available as an added accessory.
