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

From presentations and panel discussions to worship services and live productions, different speakers often need different ways to be heard. The Galaxy Audio CSL4-SVVVP 4-channel digital UHF diversity wireless system combines one headset microphone and three lavalier microphones in a versatile wireless package designed for educational programs, houses of worship, corporate presentations and multi-speaker events. Operating within the 470–507MHz UHF frequency range, the system includes four MBP48P bodypack transmitters, one HS13-UBK unidirectional wrap-around headset microphone, three LV13-UBK unidirectional lavalier microphones and a 1U rackmount receiver with four independent True Diversity channels. This configuration provides secure headset positioning for an active performer or presenter while offering discreet, hands-free lavalier pickup for three additional users. With 32-bit encrypted digital modulation, less than 3ms latency and an operating range of up to 300', the CSL4-SVVVP 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.

One Headset and Three Lavalier Microphones Support Versatile Presentations

The CSL4-SVVVP includes one HS13-UBK wrap-around headset microphone and three LV13-UBK lavalier microphones, each paired with its own MBP48P bodypack transmitter for independent wireless operation. The headset microphone provides consistent positioning near the mouth, making it particularly useful for instructors, worship leaders and presenters who move frequently or need both hands free. Its wrap-around design helps maintain microphone placement during active performances, while unidirectional pickup emphasizes the wearer's voice and reduces unwanted surrounding sound. The three lavalier microphones offer discreet alternatives for speakers, panelists and presenters who prefer microphones positioned unobtrusively on clothing. Their compact design allows users to gesture, demonstrate equipment or interact naturally with an audience without holding a microphone. 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 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. 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-SVVVP'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 the headset microphone and three 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 secure headset operation, three discreet lavalier channels, intelligent wireless coordination and independent audio processing, the Galaxy Audio CSL4-SVVVP provides a flexible solution for venues and production teams that need dependable hands-free wireless performance with straightforward setup and control.
