News
The Concert 77 system is a UHF wireless solution ideal for any professional application. UHF means Ultra High Frequency, which translates to crystal clear operation with no interference, traditionally available on only the most expensive systems. Now UHF performance and reliability are affordable thanks to Concert 77.

The new CT7 beltpack transmitter can be configured as a lavalier, headset, wind instrument and guitar system thanks to the popular locking P3 input connection. The CT7 also features a three-segment battery indicator, separate power and audio on/off switches, adjustable AF level (audio gain), and 12 hours of battery life on a single 9-volt battery.

The CR77 true-diversity half-rack UHF receiver is the core of the Concert 77 system. 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 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. 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.
