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

Give every performer the freedom to be heard with a wireless microphone system that adapts to different voices and performance styles. The Galaxy Audio CSL4-HHSSP 4-channel digital UHF diversity wireless system combines two handheld microphones and two headset microphones in a versatile package designed for live performances, houses of worship, theatrical productions and professional presentations. Operating within the 470–507MHz UHF frequency range, the system includes two HH48P handheld transmitters with dynamic cardioid capsules, two MBP48P bodypack transmitters with HS13-UBK unidirectional headset microphones and a 1U rackmount receiver with four independent True Diversity channels. This configuration gives two performers traditional handheld microphone control while allowing two others to move freely with hands-free vocal pickup. With 32-bit encrypted digital modulation, less than 3ms latency and an operating range of up to 300', the CSL4-HHSSP 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.

Two Handheld Microphones and Two Headsets Support Flexible Performances

The CSL4-HHSSP includes two HH48P handheld wireless transmitters and two MBP48P bodypack transmitters paired with HS13-UBK unidirectional headset microphones, providing a balanced configuration for productions requiring both handheld and hands-free operation. 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 presentations. The included headset microphones allow performers, instructors and presenters to keep their hands free while speaking, singing or interacting with equipment. Their unidirectional pickup patterns help emphasize the wearer's voice while limiting surrounding sound. All four microphones operate through independent wireless channels, allowing two handheld users and two headset users to perform simultaneously without sharing equipment. This combination makes the system particularly useful for worship teams, theatrical productions, fitness instruction and events 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-HHSSP'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 headset 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 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, hands-free operation, intelligent wireless coordination and independent audio processing, the Galaxy Audio CSL4-HHSSP offers a flexible wireless solution for venues and production teams that need dependable multichannel microphone performance with straightforward setup and control.
