In productions where presenters, speakers and performers are constantly moving, dependable wearable wireless systems become just as important as the sound system itself. The Galaxy Audio CSL4-HVVVM 4-channel digital UHF wireless microphone system is designed for exactly those environments, combining four independent digital UHF True-Diversity wireless channels into a streamlined 1U rackmount solution optimized for handheld and lavalier operation. This configuration includes one CSL4 quad-channel receiver, one HH48 handheld dynamic cardioid microphone transmitter, three 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 help 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 demanding 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 identify clean operating frequencies, 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 stable low-noise wireless audio performance for professional live sound and presentation use.
Handheld Versatility and Discreet Lavalier Operation
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 during live speaking or singing applications. Its LCD display provides quick access to frequency, mute and battery status during operation. The three included MBP48 bodypack transmitters paired with LV13-UBK-GAL lavalier microphones provide discreet low-profile wireless solutions ideal for presenters, educators, worship leaders and theatrical productions where unobtrusive microphone placement is essential. The lavalier microphones feature unidirectional pickup patterns that help maintain intelligibility while reducing 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 integration into mixers and installed sound systems. Integrated 7-band EQ processing per channel allows fast tonal adjustments directly from the receiver, while customizable LCD display colors help visually organize channels during 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-HVVVM delivers dependable mixed-transmitter wireless performance for a broad range of live sound and presentation environments.
