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

Keep every performer connected to the audience with hands-free wireless audio designed for movement, flexibility and clear communication. The Galaxy Audio CSL4-SSSVP 4-channel digital UHF diversity wireless system combines three headset microphones and one lavalier 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 four MBP48P bodypack transmitters, three HS13-UBK unidirectional wrap-around headset microphones, one LV13-UBK unidirectional lavalier microphone and a 1U rackmount receiver with four independent True Diversity channels. This configuration provides secure headset positioning for three active performers while offering discreet lavalier pickup for a fourth speaker. With 32-bit encrypted digital modulation, less than 3ms latency and an operating range of up to 300', the CSL4-SSSVP 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 Headset Microphones and One Lavalier Support Hands-Free Performances

The CSL4-SSSVP includes three HS13-UBK wrap-around headset microphones and one LV13-UBK lavalier microphone, each paired with its own MBP48P bodypack transmitter for independent wireless operation. The headset microphones provide consistent positioning near the mouth, making them particularly useful for theatrical performers, fitness instructors and presenters who move frequently or need both hands free. Their wrap-around design helps maintain microphone placement during active performances, while unidirectional pickup emphasizes the wearer's voice and reduces unwanted surrounding sound. The included lavalier microphone offers a discreet alternative for speakers, worship leaders and panelists who prefer a microphone positioned unobtrusively on clothing. With four complete bodypack microphone setups included, the system allows all four users to speak or perform simultaneously while selecting the microphone style best suited to their role.

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 and presenters 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. A 50Hz–16kHz frequency response further supports clear reproduction of vocals and spoken-word audio across all four channels.

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

Each of the CSL4-SSSVP'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 lavalier 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 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 three secure headset microphones, a discreet lavalier option, intelligent wireless coordination and independent audio processing, the Galaxy Audio CSL4-SSSVP provides a flexible solution for venues and production teams that need dependable hands-free wireless performance with straightforward setup and control.
