The Galaxy Audio CSL4-HSSSM 4-channel digital UHF wireless microphone system is built for productions that require a combination of handheld vocal performance and secure hands-free headset operation without sacrificing wireless stability or audio quality. This configuration includes one CSL4 quad-channel receiver, one HH48 handheld dynamic cardioid microphone transmitter, three MBP48 bodypack transmitters paired with HS13-UBK-GAL headset microphones, antennas, power supply, combined-output cable and quick-start guide for a complete ready-to-deploy wireless setup. Features like auto frequency scanning, RF spectrum analysis, IR sync, customizable LCD displays and onboard 7-band EQ per channel streamline setup while delivering reliable professional-grade wireless performance for worship services, theater productions, schools, conferences and live presentations.
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 designed for dependable 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 quickly locate clean operating frequencies, 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 stable low-noise wireless performance for demanding live applications.
Headset Mobility and Handheld Vocal Flexibility
The included HH48 handheld transmitter features a dynamic cardioid microphone capsule designed for focused vocal clarity and strong rejection of unwanted ambient noise and feedback. Its LCD display provides quick access to frequency, mute and battery information during live use. The three included MBP48 bodypack transmitters paired with HS13-UBK-GAL headset microphones provide a secure hands-free solution ideal for instructors, worship leaders, theater performers and presenters who require unrestricted movement during performances or presentations. The headset microphones feature a comfortable dual-ear wraparound design that helps maintain secure positioning throughout extended use and energetic stage activity.
Professional Connectivity and Expandable System Design
The CSL4 receiver provides balanced XLR outputs for each individual channel plus a summed unbalanced 1/4" output for simplified mixer integration and installed sound applications. Integrated 7-band EQ processing per channel allows quick tonal shaping directly from the receiver, while customizable LCD display colors help engineers organize channels visually during operation. The system also supports expansion with optional Galaxy Audio accessories including lavalier microphones, antenna distribution systems and directional antennas for larger wireless installations and advanced RF management. Compact, professional and highly adaptable, the CSL4-HSSSM delivers dependable mixed-transmitter wireless performance for a wide range of live sound and presentation environments.
