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

Four Channels of Digital UHF Wireless Performance

The CSL4 receiver integrates four fully independent digital True-Diversity wireless channels into a compact single-rack-space chassis built for multi-user operation in demanding RF environments. Operating in the M3 frequency range (516–558MHz), 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 operating frequencies quickly, while IR Sync instantly pairs transmitters to their assigned channels. With less than 3 ms latency, 32-bit encrypted digital transmission and operating range up to 300', the system delivers dependable low-noise audio performance with secure wireless stability.

Three Handhelds and One Bodypack for Flexible Applications

The three included HH48 handheld transmitters feature dynamic cardioid microphone capsules designed for focused vocal clarity and strong rejection of unwanted stage noise and feedback. Their LCD displays provide quick monitoring of frequency, mute and battery information during performances and presentations. The included MBP48 bodypack transmitter adds additional flexibility for use with compatible headset microphones, lavaliers or instrument applications, making the system ideal for productions requiring both traditional handheld vocal microphones and hands-free wireless operation. Adjustable bodypack gain settings and detailed transmitter status displays help tailor the system to a wide range of performance and presentation needs.

Professional Connectivity and Expandable Wireless Control

The CSL4 receiver provides balanced XLR outputs for each individual channel plus a summed unbalanced 1/4" output for simplified mixer integration. Integrated 7-band EQ processing per channel allows fast tonal shaping directly from the receiver, while customizable LCD display colors help engineers organize channels visually during live operation. The system also supports expansion with optional Galaxy Audio accessories including lavalier microphones, headset microphones, directional antennas and antenna distribution systems for larger installations and advanced wireless setups. Compact, professional and highly adaptable, the CSL4-HHHBM delivers dependable mixed-transmitter wireless performance for a broad range of live sound environments.
