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.
All of the AirLine transmitters operate on inexpensive and lightweight AAA batteries that offer 14 hours of operation on a single battery.

The compact AX1 Handheld UHF Transmitter allows a user to convert any dynamic microphone (or battery powered condenser mic) 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.
Despite it's small size, the AX1 features a power switch, microphone input level control and a power/battery LED that conveniently indicates when there is less than two hours of battery life remaining. The AX1 also operates for up to 14 hours on a single AAA battery. Plus, as a UHF transmitter, it operates on clearer frequencies with less interference.
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 (RK55 rack mount kit).

The Q7 dynamic microphone brings a high level of accuracy and audio performance to vocal miking applications thanks to its low mass, neodymium element. Using state-of-the-art microphone technology, the Q7 is engineered to the finest detail to provide the ultimate in sound reproduction and professionalism.


The Q7 is a handheld, dynamic microphone that excels in both live performance and recording applications. Equipped with a linear frequency response for superior reproduction, it is also designed to withstand high sound pressure levels.
Thanks to a high level of sensitivity, the Q7 will pick up all the nuances of any performance with exceptional clarity and detail. Plus, it employs a tight supercardioid pattern to reduce feedback and effectively reject signals not originating directly in front of the mic capsule.
A special shockmounted element also minimizes handling noise and provides additional protection. And with a rugged zinc alloy die-casting case, the Q7 will provide reliable performance in even the most demanding environments.
