Whether you're upgrading a wireless system or replacing a receiver, the CR77 offers seamless integration and dependable functionality.

True Diversity Reception Reduces Dropouts and Interference
Equipped with dual antennas and true diversity circuitry, the CR77 continuously monitors signal strength and selects the strongest path to ensure reliable audio transmission. This reduces the chance of signal dropouts and interference, especially in environments crowded with RF activity. Combined with PLL synthesized tuning, the CR77 maintains stable signal performance throughout long sessions and dynamic performances.

Multiple Output Options for Professional Integration
The CR77 receiver features balanced XLR and unbalanced 1/4" outputs, making it compatible with both professional PA systems and consumer-grade equipment. A mic/line output level switch allows users to tailor the output signal for different applications, from direct console inputs to amp connections. This flexibility ensures the unit adapts smoothly to nearly any audio setup.

Front-Panel Controls for On-the-Fly Adjustments
The front panel includes multi-segment LED meters that clearly indicate RF signal strength and audio level in real time. A large volume control dial provides quick level adjustments, while the squelch control helps eliminate unwanted background noise when the transmitter signal is weak or lost. These intuitive controls are ideal for live sound engineers who need quick feedback and responsive functionality.

Durable Design for Permanent Installs or Portable Use
Built with a rugged metal chassis and streamlined form factor, the CR77 is ideal for use in rack-mounted systems, portable sound kits, or on-the-go production rigs.
