Keeping multiple performers connected wirelessly is one thing—making every voice sound clear, stable and effortless under pressure is another challenge entirely. The Galaxy Audio CSL4-HHVVM 4-channel digital UHF wireless microphone system is built for productions that require both traditional handheld vocal microphones and discreet lavalier operation in a single professional wireless platform. This configuration includes one CSL4 quad-channel receiver, two HH48 handheld dynamic cardioid microphone transmitters, two MBP48 bodypack transmitters paired with LV13-UBK-GAL lavalier 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 simplify setup while delivering stable, professional-grade wireless performance for worship services, theater productions, conferences, schools and live event applications.
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 dependable operation in busy 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 integrated 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 modulation and operating range up to 300', the system delivers reliable low-noise wireless audio performance for professional stage and presentation use.
Handheld Vocal Control and Discreet Lavalier Operation
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 live performances and presentations. The two included MBP48 bodypack transmitters paired with LV13-UBK-GAL lavalier microphones provide a low-profile wireless solution ideal for presenters, worship leaders, theater productions and conference environments where discreet microphone placement is essential. The lavalier microphones feature unidirectional pickup patterns that help maintain speech intelligibility while minimizing surrounding room noise.
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 and installed sound applications. Integrated 7-band EQ processing per channel allows quick tonal adjustments directly from the receiver, while customizable LCD display colors help visually organize channels during live operation. The system also supports expansion with optional Galaxy Audio accessories including headset microphones, antenna distribution systems and directional antennas for larger wireless installations and advanced RF management. Compact, professional and highly adaptable, the CSL4-HHVVM delivers dependable mixed-transmitter wireless performance for a broad range of live sound and presentation environments.
