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

Give every voice the freedom to move while keeping complete control over your live sound. The Galaxy Audio CSL4-HHHHP 4-channel digital UHF diversity wireless handheld microphone system delivers four independent wireless microphone channels in a streamlined, rackmount design built for live performances, presentations, houses of worship and professional events. Operating within the 470–507MHz UHF frequency range, the system combines four HH48P handheld transmitters with a 1U CSL4 receiver featuring True Diversity reception, automatic frequency scanning and an integrated RF Spectrum Analyzer. Each handheld microphone features a dynamic cardioid capsule designed to capture clear, focused vocals while reducing unwanted background sound. With 32-bit encrypted digital modulation, less than 3 ms latency and an operating range of up to 300', the CSL4-HHHHP provides reliable wireless performance for applications requiring multiple speakers or vocalists. Individual 7-band EQ, color-changing LCD displays and flexible audio outputs give operators the tools needed to manage all four microphone channels from a single receiver.

Four Dynamic Cardioid Handheld Microphones Support Multiple Performers

The CSL4-HHHHP includes four HH48P handheld wireless transmitters, providing a complete four-microphone solution for vocal ensembles, panel discussions, worship teams and events with multiple presenters. Each transmitter features a dynamic cardioid microphone element that emphasizes sound arriving from the front while reducing pickup from the sides and rear, helping maintain vocal clarity in environments with competing sound sources. Independent wireless channels allow all four microphones to operate simultaneously, eliminating the need to share microphones between performers or presenters. Each handheld operates on two AA batteries and provides approximately eight hours of battery life, supporting extended rehearsals, services and live events. With transmitter RF output power of up to 10mW, the system delivers practical wireless mobility while maintaining the convenience of traditional handheld microphone operation.

True Diversity Reception and Intelligent Frequency Management Simplify Setup

The CSL4 receiver features four independent True Diversity wireless channels designed to maintain consistent signal reception as performers move throughout the venue. Operating across 1,480 selectable frequencies within the 470–507MHz band, the system provides flexibility for finding suitable operating channels in different RF environments. Automatic 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 transmitter setup by transferring the appropriate settings from the receiver to each handheld microphone. Color-changing LCD displays provide convenient visual feedback for monitoring system operation, while 32-bit encrypted digital modulation supports secure audio transmission with less than 3 ms latency. Together, these features streamline wireless coordination for live sound engineers, mobile entertainers and production teams managing multiple microphones.

Individual 7-Band EQ and Flexible Outputs Provide Precise Audio Control

Each of the CSL4-HHHHP's four wireless channels features an independent 7-band equalizer, allowing operators to shape individual microphone signals to accommodate different voices, performance styles and room acoustics. This channel-specific control makes it easier to balance multiple vocalists or presenters without applying the same tonal adjustments to every microphone. The 1U rackmount receiver provides four individual 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 four handheld microphones, intelligent frequency management and independent audio processing, the Galaxy Audio CSL4-HHHHP offers a versatile wireless solution for venues and production teams that need dependable multichannel microphone performance with straightforward setup and control.
