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

From corporate presentations and worship services to educational programs and live events, clear communication starts with the right microphone for every speaker. The Galaxy Audio CSL4-HHVVP 4-channel digital UHF diversity wireless system combines two handheld microphones and two lavalier microphones in a flexible wireless package designed for productions requiring both traditional vocal pickup and discreet, hands-free operation. Operating within the 470–507MHz UHF frequency range, the system includes two HH48P handheld transmitters with dynamic cardioid capsules, two MBP48P bodypack transmitters with LV13-UBK unidirectional lavalier microphones and a 1U rackmount receiver with four independent True Diversity channels. This configuration allows two performers or presenters to use handheld microphones while two others benefit from low-profile lavalier pickup. With 32-bit encrypted digital modulation, less than 3ms latency and an operating range of up to 300', the CSL4-HHVVP provides 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.

Two Handheld Microphones and Two Lavaliers Support Versatile Applications

The CSL4-HHVVP includes two HH48P handheld wireless transmitters and two MBP48P bodypack transmitters paired with LV13-UBK unidirectional lavalier microphones, giving users flexible microphone options for different presentation and performance requirements. The handheld microphones feature dynamic cardioid capsules designed to emphasize the primary sound source while reducing unwanted background pickup, making them suitable for vocal performances, announcements and audience interaction. The included lavalier microphones provide discreet, hands-free operation for speakers, instructors and presenters who need to move naturally or demonstrate equipment while speaking. Their unidirectional pickup patterns help focus on 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 balanced configuration makes the system particularly useful for panel discussions, worship services, classrooms and professional events requiring a combination of handheld and unobtrusive microphone placement.

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-HHVVP'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 two handheld microphones and two lavalier microphones 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. Its compact rackmount format simplifies integration into portable sound systems, installed audio racks and professional mixing environments. Combining handheld versatility, discreet lavalier operation, intelligent wireless coordination and independent audio processing, the Galaxy Audio CSL4-HHVVP offers a flexible wireless solution for venues and production teams that need dependable multichannel microphone performance with straightforward setup and control.
