  • Four Independent True-Diversity Receivers Share One 1U Rack Chassis For Space Efficiency
  • Auto Frequency Scanning And RF Spectrum Analyzer Simplify Coordination In Congested RF Environments
  • IR Sync Pairs Each MBP48 Bodypack To Its Receiver Channel Instantly
  • Per-Channel 7-Band Adjustable EQ Lets Operators Tailor Each Wireless Signal Independently
  • Color-Coded LCD Displays With Six Options Enable Fast Visual Channel Identification
  • 32-Bit Encrypted Digital Modulation Protects Transmission Security
  • Balanced XLR Output Per Channel Plus Combined Unbalanced Output Supports Flexible Cabling

The Galaxy Audio CSL4 is built for sound engineers and integrators who need to manage multiple wireless channels without consuming rack space or fighting interference. Four independent True-Diversity UHF receivers share a single 1U chassis, making it a practical solution for worship teams, theatrical productions, corporate AV installs, and multi-performer live sound where rack economy and RF reliability are both non-negotiable. The included MBP48 bodypacks offer four-position input gain switching and a full-status LCD, giving talent and crew clear feedback on frequency, battery, mute, and RF power at a glance.

Where single-channel systems require separate rack units and manual frequency coordination, the CSL4 consolidates that workflow. Auto Frequency Scanning and an onboard RF Spectrum Analyzer let operators find clean frequencies quickly across three available bands, supporting up to 18 compatible systems simultaneously in dense RF environments. IR Sync eliminates manual frequency entry by pairing each transmitter to its corresponding receiver instantly. Balanced XLR outputs on every channel feed directly into stage boxes or FOH consoles, while the summed unbalanced quarter-inch output provides a simplified feed option for smaller setups or monitoring. Per-channel 7-band EQ and color-coded LCD displays let operators differentiate and tune each channel independently without leaving the rack.
