AirLine 77 is Samson's newest version of the AirLine series that features the first micro-technology transmitters in the industry. Traditional wireless systems consist of belt-packs and wires that hinder the performer. With AirLine, you get a true wireless system because there are no belt-packs and no cables, allowing the user complete freedom.
The AirLine headset transmitters feature the Samson QV Vocal microphone elements. QV 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 exercise routines.
All of the AirLine transmitters operate on inexpensive and lightweight AAA batteries that offer 14 hours of operation on a single battery.
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. Two CR77 receivers can be rack mounted together in a single space rack adapter available as an added accessory.
