Product Description
The Concert 77 Guitar System is a high-performance UHF wireless solution that’s ideal for any application where the freedom of mobility is an important part of your performance. With a guitar tone that stays uncolored and pure as the wire, Concert 77 provides flawless reception and professional sound at any gig in any location.
The CT7 belt pack transmitter clips securely to your guitar strap, and thanks to the popular locking P3 input connection and included guitar cable, you’re ready to rock, right out of the box.
The CR77 true-diversity half-rack UHF receiver is at the core of the system. A synthesized PLL frequency control circuitry keeps the signal locked and true while dual tuned molded antennas with LEDs monitor the true-diversity operation.
The CR77 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. Its rear panel features balanced XLR and unbalanced 1/4-inch outputs allowing flexible connection options.
Where two wireless systems are required, two CR77 receivers can be rack mounted together in a single-space rack adapter available as an additional accessory.
