Features like auto frequency scanning, RF spectrum analysis, IR sync, customizable LCD displays and onboard 7-band EQ per channel help simplify setup while delivering stable, professional-grade wireless performance for theaters, worship teams, presenters, schools and live production environments.

Four Channels of Digital UHF Wireless Performance

The CSL4 receiver combines four fully independent digital True-Diversity wireless channels into a compact single-rack-space chassis engineered for reliable operation in crowded RF environments. Operating within the 516–558MHz frequency range, the system provides access to hundreds of selectable frequencies with support for multiple simultaneous wireless systems depending on the operating band. Auto frequency scanning and the built-in RF spectrum analyzer help identify clean frequencies quickly, while IR Sync instantly pairs transmitters with their assigned channels. With less than 3 ms latency, 32-bit encrypted digital modulation and operating range up to 300', the system delivers dependable low-noise wireless audio for professional live sound applications.

Handheld and Headset Flexibility for Active Performers

The two included HH48 handheld transmitters feature dynamic cardioid microphone capsules designed for focused vocal clarity and strong rejection of unwanted ambient noise and feedback. Their LCD displays provide quick access to frequency, mute and battery information during performances and presentations. The two included MBP48 bodypack transmitters paired with HS13-UBK-GAL headset microphones provide a secure hands-free wireless solution ideal for worship leaders, fitness instructors, theater performers and presenters who require unrestricted movement. The headset microphones feature a comfortable dual-ear wraparound design that helps keep the microphone stable during energetic performances and extended use.
