Galaxy Audio CSL4-HHHVM 4-Channel Digital UHF Wireless Microphone System - Frequency CODE M3 516-558MHz

Some live productions require the flexibility of handheld vocal microphones while still giving one performer the freedom of a discreet lavalier system. The Galaxy Audio CSL4-HHHVM 4-channel digital UHF wireless microphone system is designed for those mixed-use environments, combining four independent digital UHF True-Diversity wireless channels into a streamlined 1U rackmount solution built for demanding stage and installed sound applications. This configuration includes one CSL4 quad-channel receiver, three HH48 handheld dynamic cardioid microphone transmitters, one MBP48 bodypack transmitter paired with an LV13-UBK-GAL lavalier microphone, antennas, power supply, combined-output cable and quick-start guide for a complete performance-ready wireless setup. Features like auto frequency scanning, RF spectrum analysis, IR sync, customizable LCD displays and onboard 7-band EQ per channel simplify operation while delivering stable, professional-grade wireless audio across multiple performers and speaking 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 engineered for reliable 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 built-in RF spectrum analyzer help quickly identify 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 dependable low-noise wireless performance for professional live sound applications.

Handheld Vocal Control and Lavalier Flexibility

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 access to frequency, mute and battery information during live operation. The included MBP48 bodypack transmitter paired with the LV13-UBK-GAL lavalier microphone adds a discreet wireless solution ideal for presenters, instructors, worship leaders and theatrical performances where low-profile microphone placement is preferred. The lavalier’s unidirectional pickup pattern helps maintain intelligibility while minimizing surrounding ambient noise in active performance environments.

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 integration into mixers and installed sound systems. Integrated 7-band EQ processing per channel allows fast tonal shaping directly from the receiver, while customizable LCD display colors help visually organize channels during live events. 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-HHHVM delivers dependable mixed-transmitter wireless performance for a broad range of live sound and presentation environments.
