Galaxy Audio CSL4-SSSSP 4-Channel Digital UHF Diversity Wireless System - 470-507 MHz

Keep every voice clear and every performer moving freely with a wireless microphone system built for hands-free communication. The Galaxy Audio CSL4-SSSSP 4-channel digital UHF diversity wireless headset microphone system provides four complete headset microphone channels in a streamlined package designed for theater productions, houses of worship, educational programs, fitness instruction and professional presentations. Operating within the 470–507MHz UHF frequency range, the system includes four MBP48P bodypack transmitters paired with four HS13-UBK unidirectional wrap-around headset microphones and a 1U rackmount receiver featuring four independent True Diversity channels. This configuration provides secure, consistent microphone positioning for presenters and performers who need to move naturally while speaking, singing or interacting with an audience. With 32-bit encrypted digital modulation, less than 3ms latency and an operating range of up to 300', the CSL4-SSSSP delivers responsive wireless audio for demanding multichannel applications. Individual seven-band EQ, color-changing LCD displays and intelligent frequency management tools provide convenient control over all four microphone channels.

Four Wrap-Around Headset Microphones Provide Secure Hands-Free Operation

The CSL4-SSSSP includes four MBP48P bodypack transmitters and four HS13-UBK unidirectional headset microphones, providing a complete hands-free wireless solution for productions involving multiple active performers or presenters. Each headset features a wrap-around, dual-ear design that helps maintain consistent microphone positioning near the mouth, making it particularly useful for theatrical performances, fitness classes, worship services and educational presentations. The unidirectional pickup pattern emphasizes the wearer's voice while reducing unwanted surrounding sound, helping maintain vocal clarity in environments with multiple sound sources. Unlike handheld microphones, the headset design allows performers to gesture, demonstrate equipment or move freely without interrupting their presentation. Each bodypack operates through its own independent wireless channel, allowing all four microphones to be used simultaneously without sharing equipment. This configuration is especially practical for productions where consistent hands-free microphone placement is essential throughout a performance.

True Diversity Reception and Intelligent Frequency Management Simplify Setup

The CSL4 receiver features four independent True Diversity wireless channels designed to maintain dependable signal reception as presenters and performers move throughout the venue. Operating across 1,480 selectable frequencies within the 470–507MHz P-band, the system provides flexibility for finding suitable operating channels in different RF environments. Auto Frequency Scan helps identify available frequencies, while the integrated RF Spectrum Analyzer provides additional visibility into surrounding wireless activity for more informed channel selection. Once frequencies are assigned, IR Sync simplifies setup by transferring the appropriate settings from the receiver to each compatible bodypack transmitter. Color-changing LCD displays provide convenient visual feedback during operation, while 32-bit encrypted digital modulation supports secure audio transmission with less than 3ms latency. Together, these features streamline wireless coordination for sound engineers, educators and production teams managing multiple headset microphones.

Individual Seven-Band EQ and Flexible Outputs Provide Precise Audio Control

Each of the CSL4-SSSSP's four wireless channels features an independent seven-band adjustable equalizer, allowing sound engineers to tailor individual microphone signals to different voices, performance styles and room acoustics. This channel-specific processing makes it easier to balance multiple headset users without applying identical tonal adjustments to every microphone. The 1U rackmount receiver provides four balanced XLR outputs for routing each headset microphone to a separate mixer channel, along with a summed 1/4" output for applications requiring a combined audio feed. Its compact rackmount format simplifies integration into portable sound systems, installed audio racks and professional mixing environments. Combining four complete headset microphone channels, intelligent wireless coordination and independent audio processing, the Galaxy Audio CSL4-SSSSP provides a flexible solution for venues and production teams that need dependable hands-free wireless performance with straightforward setup and control.
