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

Give every presenter the freedom to move while keeping a traditional handheld microphone ready for announcements and audience interaction. The Galaxy Audio CSL4-HVVVP 4-channel digital UHF diversity wireless system combines one handheld microphone and three lavalier microphones in a versatile wireless package designed for presentations, houses of worship, educational programs and multi-speaker events. Operating within the 470–507MHz UHF frequency range, the system includes one HH48P handheld transmitter with a dynamic cardioid capsule, three MBP48P bodypack transmitters paired with LV13-UBK unidirectional lavalier microphones and a 1U rackmount receiver with four independent True Diversity channels. This configuration provides discreet, hands-free pickup for three speakers while reserving a handheld microphone for lead vocals, announcements or audience participation. With 32-bit encrypted digital modulation, less than 3ms latency and an operating range of up to 300', the CSL4-HVVVP 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 Lavalier Microphones and One Handheld Support Versatile Presentations

The CSL4-HVVVP includes three MBP48P bodypack transmitters with LV13-UBK lavalier microphones and one HH48P handheld wireless transmitter, providing flexible microphone options 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 lectures, worship services, panel discussions and corporate presentations. Their compact design allows discreet placement on clothing, giving presenters the freedom to gesture, demonstrate equipment or move naturally without holding a microphone. The handheld transmitter features a dynamic cardioid capsule that focuses on the primary sound source while limiting background pickup, making it practical for announcements, featured speakers and audience interaction. All four microphones operate through independent wireless channels, allowing three lavalier users and one handheld user to speak or 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 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 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, educators and production teams managing multiple microphones.

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

Each of the CSL4-HVVVP'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 three lavalier 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 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 discreet lavalier microphones, a versatile handheld channel, intelligent wireless coordination and independent audio processing, the Galaxy Audio CSL4-HVVVP provides a flexible solution for venues and production teams that need dependable multichannel wireless performance with straightforward setup and control.
