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

From lead vocalists and presenters to performers who need their hands free, every voice deserves a reliable connection to the audience. The Galaxy Audio CSL4-HHHSP 4-channel digital UHF diversity wireless system combines three handheld microphones and one headset microphone in a versatile wireless package designed for live performances, houses of worship, presentations 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 HS13-UBK unidirectional headset microphone and a 1U rackmount receiver with four independent True Diversity channels. This configuration gives three performers the flexibility of traditional handheld microphones while allowing a fourth 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-HHHSP delivers responsive wireless audio for demanding multichannel applications. Individual seven-band EQ, color-changing LCD displays and intelligent frequency management tools provide additional control for coordinating multiple microphones from a single receiver.

Three Handheld Microphones and One Headset Support Versatile Performances

The CSL4-HHHSP includes three HH48P handheld wireless transmitters and one MBP48P bodypack transmitter paired with an HS13-UBK unidirectional headset microphone, giving performers and presenters flexible options for different speaking and singing applications. The handheld microphones feature dynamic cardioid capsules that focus on sound arriving from the front while reducing unwanted background pickup, making them suitable for vocal performances, announcements and panel discussions. The included headset microphone provides hands-free operation for instructors, worship leaders, theatrical performers and presenters who need to move naturally or interact with equipment while speaking. Each microphone operates through its own independent wireless channel, allowing all four users to perform simultaneously without sharing equipment. This mixed configuration provides the convenience of traditional handheld microphones alongside the freedom of a bodypack-powered headset system, making it a practical solution for productions with varied microphone requirements.

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, greater than 80dB signal-to-noise ratio and less than 0.5% total harmonic distortion at 1kHz further support clear, consistent audio reproduction across all four channels.

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

Each of the CSL4-HHHSP'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 headset 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 unbalanced 1/4" output for applications requiring a shared audio feed. Measuring 1.79" x 19" x 7", the receiver integrates into standard equipment racks and operates from a 12V DC, 1000mA power supply. Combining handheld versatility, hands-free operation, intelligent wireless coordination and independent audio processing, the Galaxy Audio CSL4-HHHSP provides a flexible multichannel microphone solution
