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

Keep every speaker connected to the audience without the restrictions of handheld microphones. The Galaxy Audio CSL4-VVVVP 4-channel digital UHF diversity wireless lavalier microphone system provides four independent wireless lavalier channels in a streamlined package designed for presentations, houses of worship, educational facilities, theater productions and multi-speaker events. Operating within the 470–507MHz UHF frequency range, the system includes four MBP48P bodypack transmitters paired with four LV13-UBK unidirectional lavalier microphones and a 1U rackmount receiver featuring four independent True Diversity channels. This configuration provides discreet, hands-free voice pickup for presenters and performers who need to move naturally while speaking 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-VVVVP 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 Wireless Lavalier Microphones Provide Discreet Hands-Free Operation

The CSL4-VVVVP includes four MBP48P bodypack transmitters and four LV13-UBK lavalier microphones, providing a complete hands-free wireless solution for productions involving multiple speakers or performers. Each lavalier features a unidirectional pickup pattern designed to emphasize the wearer's voice while reducing unwanted surrounding sound, making it suitable for presentations, lectures, worship services and theatrical applications. The compact lavalier design allows microphones to be positioned discreetly on clothing, helping maintain a natural appearance while giving users the freedom to gesture, demonstrate equipment or move throughout the performance area. Each bodypack operates through its own independent wireless channel, allowing all four microphones to be used simultaneously without sharing equipment. This configuration is particularly useful for panel discussions, educational programs and events where several participants require consistent, unobtrusive voice pickup.

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, with support for up to 18 compatible systems. 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, greater than 80dB signal-to-noise ratio and less than 0.5% total harmonic distortion at 1kHz further support clear, consistent voice reproduction across all four channels.

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

Each of the CSL4-VVVVP'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 multiple presenters without applying identical tonal adjustments to every microphone. The 1U rackmount receiver provides four balanced XLR outputs for routing each lavalier microphone to a separate mixer channel, along with a summed unbalanced 1/4" output for applications requiring a combined audio feed. Measuring 1.79" x 19" x 7" and weighing 3.34 lb., the receiver integrates into standard equipment racks and operates from a 12V DC, 1000mA power supply. Combining four complete lavalier microphone channels, intelligent wireless coordination and independent audio processing, the Galaxy Audio CSL4-VVVVP provides a flexible solution for venues and production teams that need dependable hands-free wireless performance with straightforward setup and control.
