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

Some productions need the flexibility to move seamlessly between handheld vocals and hands-free wearable systems without sacrificing wireless stability. The Galaxy Audio CSL4-HHBBM 4-channel digital UHF wireless microphone system is designed for exactly that kind of demanding live environment, combining four independent digital UHF True-Diversity wireless channels into a single streamlined rackmount solution. This configuration includes one 1U CSL4 quad-channel receiver, two HH48 handheld dynamic cardioid microphone transmitters, two MBP48 bodypack transmitters, antennas, power supply, combined-output cable and quick-start guide for a versatile mixed-transmitter wireless package ready for live performance, worship, theater, conferencing and installed sound applications. 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-grade wireless operation.

Four Channels of Digital UHF Wireless Performance

The CSL4 receiver combines four independent digital True-Diversity wireless channels into a compact single-rack-space design built for busy stages and multi-user setups. Operating within the M3 frequency range (516–558MHz), the system provides access to hundreds of selectable frequencies with support for multiple simultaneous systems depending on the operating band. Auto frequency scanning and the integrated RF spectrum analyzer help identify clean operating frequencies quickly, while IR Sync pairs transmitters instantly to 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 audio in demanding RF environments.

Flexible Combination of Handheld and Bodypack Transmitters

The two included HH48 handheld transmitters feature dynamic cardioid microphone capsules designed for focused vocal pickup and reliable feedback rejection during live speaking and singing applications. Their LCD displays provide quick monitoring of frequency, mute and battery status while PLL phase-locked operation maintains stable wireless performance. The two included MBP48 bodypack transmitters expand the system for use with compatible lavalier microphones, headset microphones or instrument sources, offering adjustable input gain and detailed status information directly from their displays. This mixed transmitter configuration makes the system especially practical for productions that combine vocal performance, presenters and wearable wireless applications in the same setup.

Professional Connectivity and Expandable System Design

The CSL4 receiver provides balanced XLR outputs for each individual channel along with a summed unbalanced 1/4" output for simplified mixer integration. Built-in 7-band EQ processing per channel allows quick tonal adjustments directly from the receiver, while customizable LCD display colors help organize channels visually during live operation. The system also supports expansion with optional Galaxy Audio accessories including headset microphones, lavaliers, directional antennas and antenna distribution systems for larger installations and advanced wireless configurations. Compact, professional and highly adaptable, the CSL4-HHBBM delivers reliable mixed-transmitter wireless performance for a wide variety of live sound and installed audio environments.
