Not every wireless setup needs four handheld microphones—sometimes flexibility between handheld and bodypack operation is what keeps a production running smoothly. The Galaxy Audio CSL4-HBBBM 4-channel digital UHF wireless microphone system is designed for demanding live environments that require a mix of vocal, presentation and wearable wireless solutions in a single streamlined package. Combining four independent digital UHF True-Diversity receivers into a compact 1U rackmount chassis, the system includes one HH48 handheld dynamic cardioid microphone transmitter, three MBP48 bodypack transmitters, antennas, power supply, combined-output cable and quick-start guide for immediate multi-channel deployment. 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 production environments.
Four Channels of Digital Wireless Performance
The CSL4 receiver combines four fully independent digital True-Diversity wireless channels into a compact single-rack-space design built for multi-user live sound applications. 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 integrated RF spectrum analyzer streamline operation in crowded RF environments, while IR Sync allows transmitters to pair instantly with their assigned channels. With less than 3 ms latency, 32-bit encrypted digital transmission and operating range up to 300', the system delivers reliable wireless performance with clean, low-noise audio quality.
Mixed Handheld and Bodypack Flexibility
The included HH48 handheld transmitter features a dynamic cardioid microphone capsule designed for focused vocal clarity and strong feedback rejection, making it ideal for presenters, singers and spoken-word applications. Its LCD display provides quick access to frequency, mute and battery information during live operation. The three included MBP48 bodypack transmitters expand the system for use with compatible lavalier microphones, headset microphones or instrument applications, offering adjustable input gain and detailed status monitoring directly from their LCD displays. This mixed configuration makes the CSL4-HBBBM especially useful for productions requiring both traditional handheld vocal microphones and more discreet wearable wireless solutions.
Professional Connectivity and Expandable Operation
The CSL4 receiver provides balanced XLR outputs for each channel plus a summed unbalanced 1/4" output for simplified integration into mixers and installed sound systems. Integrated 7-band EQ processing per channel allows quick tonal shaping directly from the receiver, while customizable display colors help engineers visually organize multiple channels during busy productions. The system can also expand with optional Galaxy Audio accessories including lavalier microphones, headset microphones, antenna distribution systems and directional antennas for larger installations and advanced wireless setups. Compact, professional and highly adaptable, the CSL4-HBBBM system delivers dependable mixed-transmitter wireless performance for a wide range of live sound applications.
