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

Some performances demand secure microphone placement, while others call for discreet vocal pickup that keeps the focus on the speaker. The Galaxy Audio CSL4-SSVVP 4-channel digital UHF diversity wireless system combines two headset microphones and two lavalier microphones in a versatile wireless package designed for houses of worship, theatrical productions, presentations, educational programs and live events. Operating within the 470–507MHz UHF frequency range, the system includes four MBP48P bodypack transmitters, two HS13-UBK unidirectional headset microphones, two LV13-UBK unidirectional lavalier microphones and a 1U rackmount receiver with four independent True Diversity channels. This configuration provides secure headset positioning for active performers alongside low-profile lavalier pickup for presenters who prefer a less visible microphone. With 32-bit encrypted digital modulation, less than 3ms latency and an operating range of up to 300', the CSL4-SSVVP 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.

Two Headsets and Two Lavaliers Support Different Performance Styles

The CSL4-SSVVP includes two HS13-UBK wrap-around headset microphones and two LV13-UBK lavalier microphones, 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 instructors, theatrical performers 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 two lavalier microphones offer a discreet alternative for speakers, worship leaders and panelists who prefer a microphone that can be 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-SSVVP's four wireless channels features an independent seven-band adjustable equalizer, allowing sound engineers to tailor individual microphone signals to different voices, speaking styles and room acoustics. This channel-specific processing makes it easier to balance headset and lavalier microphones 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 two secure headset microphones, two discreet lavaliers, intelligent wireless coordination and independent audio processing, the Galaxy Audio CSL4-SSVVP provides a flexible solution for venues and production teams that need dependable hands-free wireless performance with straightforward setup and control.
