Description

Details

The AirLine 77 Headset System offers a true wireless experience with no beltpacks and no cables, allowing complete freedom of mobility.

The AirLine headset transmitters feature the Samson Qe Fitness microphone elements. The Qe headsets were 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 group fitness classes.

The Qe is designed with unidirectional microphones and cardioid pickup patterns that reject feedback. The Qe Fitness headset is ideal for group fitness instructors who need a durable headset that will remain in place despite repetitious movement. Specifically designed for aerobics and fitness training, the Qe headset mic is light, comfortable and features a water-resistant mic element to protect against perspiration. This mic can be individually adjusted for a perfect fit. The transmitter offers 14 hours of operation on a single AAA battery.

The core of the receiver system is the CR77 true-diversity half-rack UHF receiver. It's designed to work flawlessly with AirLine UHF transmitters. Featuring dual tuned, molded antenna, 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 the LED meters monitor the system's operation. The rear panel features balanced XLR and unbalanced 1/4-inch outputs allowing flexible connection options. In addition, two CR77 receivers can be rack-mounted together in a single space rack adapter available as an added accessory.

With AirLine 77 Headset System, you get complete wireless freedom that's good to go anywhere the music takes you.
