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

Keep performers moving freely while ensuring every voice stays connected to the audience. The Galaxy Audio CSL4-HSSSP 4-channel digital UHF diversity wireless system combines three hands-free headset microphones with one handheld microphone in a versatile package designed for theatrical productions, houses of worship, fitness instruction, presentations and live events. Operating within the 470–507MHz UHF frequency range, the system includes three MBP48P bodypack transmitters with HS13-UBK unidirectional dual-ear headset microphones, one HH48P handheld transmitter with a dynamic cardioid capsule and a 1U rackmount receiver with four independent True Diversity channels. This configuration allows three performers or presenters to maintain hands-free mobility while reserving a handheld microphone for announcements, lead vocals or audience interaction. With 32-bit encrypted digital modulation, less than 3ms latency and an operating range of up to 300', the CSL4-HSSSP delivers responsive wireless audio for multichannel applications. Individual seven-band EQ, color-changing LCD displays and intelligent frequency management tools provide convenient control over all four microphone channels.

Three Hands-Free Headsets and One Handheld Support Dynamic Performances

The CSL4-HSSSP includes three MBP48P bodypack transmitters paired with HS13-UBK dual-ear headset microphones, providing hands-free vocal pickup for performers, instructors and presenters who need to move naturally throughout a production. Each headset features a unidirectional pickup pattern that emphasizes the wearer's voice while reducing unwanted surrounding sound, making the configuration particularly useful for theatrical performances, fitness classes and worship services. The dual-ear design provides a secure wearing arrangement for active performers, while the bodypack transmitters allow users to speak or sing without holding a microphone. An included HH48P handheld transmitter features a dynamic cardioid capsule suited to announcements, lead vocals and other applications where traditional handheld operation is preferred. All four microphones operate through independent wireless channels, allowing three headset users and one handheld user to perform simultaneously without sharing equipment.

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 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 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, mobile entertainers and production teams managing multiple microphones.

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

Each of the CSL4-HSSSP'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 the three headset microphones and handheld microphone without applying identical tonal adjustments to every source. The 1U rackmount receiver provides four XLR outputs for routing each microphone to a separate mixer channel, along with a combined 1/4" output for applications requiring a shared audio feed. Its compact rackmount format simplifies integration into portable sound systems, installed audio racks and professional mixing environments. Combining extensive hands-free capability, handheld versatility, intelligent wireless coordination and independent audio processing, the Galaxy Audio CSL4-HSSSP provides a flexible solution for venues and production teams that need dependable multichannel microphone performance with straightforward setup and control.
