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

Bring multiple voices together with the flexibility of handheld microphones and the convenience of discreet, hands-free audio. The Galaxy Audio CSL4-HHHVP 4-channel digital UHF diversity wireless system combines three handheld microphones and one lavalier microphone in a versatile wireless package designed for live performances, presentations, houses of worship and professional events. Operating within the 470–507MHz UHF frequency range, the system includes three HH48P handheld transmitters with dynamic cardioid capsules, one MBP48P bodypack transmitter with an LV13-UBK unidirectional lavalier microphone and a 1U rackmount receiver with four independent True Diversity channels. This configuration allows three performers or presenters to use traditional handheld microphones while a fourth benefits from discreet, hands-free vocal pickup. With 32-bit encrypted digital modulation, less than 3ms latency and an operating range of up to 300', the CSL4-HHHVP provides responsive wireless audio for multichannel applications. Individual seven-band EQ, color-changing LCD displays and intelligent frequency management tools give operators convenient control over all four microphone channels.

Three Handheld Microphones and One Lavalier Support Flexible Vocal Applications

The CSL4-HHHVP includes three HH48P handheld wireless transmitters and one MBP48P bodypack transmitter paired with an LV13-UBK unidirectional lavalier microphone, providing multiple microphone options for productions with varied presentation requirements. The handheld microphones feature dynamic cardioid capsules designed to focus on the primary sound source while reducing unwanted background pickup, making them suitable for vocal performances, announcements and panel discussions. The included lavalier microphone offers a discreet alternative for speakers, instructors and presenters who need their hands free while moving, demonstrating equipment or addressing an audience. Its unidirectional pickup pattern helps emphasize the wearer's voice while limiting surrounding sound. All four microphones operate through independent wireless channels, allowing multiple users to speak or perform simultaneously without sharing equipment. This combination of handheld versatility and unobtrusive lavalier operation makes the system particularly useful for corporate presentations, worship services and live productions requiring different microphone styles.

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 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. 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-HHHVP'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 handheld microphones and lavalier microphone without applying identical tonal adjustments to every source. The 1U rackmount receiver provides four balanced XLR outputs for routing each microphone to a separate mixer channel, along with a combined 1/4" output for applications requiring a shared audio feed. Operating from a 12V DC, 1000mA power supply, the receiver integrates into standard equipment racks and professional sound systems. Combining three handheld microphones, a discreet lavalier option, intelligent wireless coordination and independent audio processing, the Galaxy Audio CSL4-HHHVP provides a flexible solution for venues and production teams that need reliable multichannel microphone performance with straightforward setup and control.
