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

From live vocals and spoken-word presentations to hands-free performances, a flexible wireless system gives every performer the freedom to work their way. The Galaxy Audio CSL4-HHHBP 4-channel digital UHF diversity wireless system combines three handheld microphones and one bodypack transmitter in a versatile package designed for bands, houses of worship, schools 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 and a 1U rackmount receiver with four independent True Diversity channels. This configuration provides three ready-to-use handheld microphones for vocalists and presenters while allowing a fourth performer to connect a compatible headset microphone, lavalier microphone or instrument accessory to the bodypack transmitter. With 32-bit encrypted digital modulation, less than 3ms latency and an operating range of up to 300', the CSL4-HHHBP delivers responsive wireless audio for multichannel applications. Individual seven-band EQ, color-changing LCD displays and intelligent frequency management tools provide convenient control over all four wireless channels. A microphone or instrument connection accessory for the bodypack transmitter is not included and must be purchased separately.

Three Handheld Microphones and One Bodypack Support Flexible Performances

The CSL4-HHHBP includes three HH48P handheld wireless transmitters and one MBP48P bodypack transmitter, providing a practical configuration for productions that rely primarily on traditional microphones while requiring an additional customizable wireless channel. Each handheld microphone features a dynamic cardioid capsule designed to emphasize the primary sound source while reducing unwanted background pickup, making them suitable for lead vocals, announcements, panel discussions and presentations. The included bodypack transmitter accommodates compatible headset microphones, lavalier microphones or instrument connections, allowing users to tailor the fourth channel to their specific performance requirements. This flexibility makes the system particularly useful for worship teams, theatrical productions, educational environments and live events combining different audio sources. All four transmitters operate through independent wireless channels, allowing three handheld users and one bodypack user to perform simultaneously. The bodypack microphone or instrument connection accessory is sold separately, giving users the freedom to select the option that best suits their application.

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. Together, these features streamline wireless coordination for sound engineers, mobile entertainers and production teams managing multiple wireless sources.

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

Each of the CSL4-HHHBP's four wireless channels features an independent seven-band adjustable equalizer, allowing sound engineers to tailor individual audio signals to different voices, instruments and room acoustics. This channel-specific processing makes it easier to balance the three handheld microphones and bodypack source without applying identical tonal adjustments to every channel. The 1U rackmount receiver provides four XLR outputs for routing each wireless source 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 three handheld microphones, a customizable bodypack channel, intelligent wireless coordination and independent audio processing, the Galaxy Audio CSL4-HHHBP provides a flexible foundation for venues and production teams that need dependable multichannel wireless performance with the freedom to select their preferred microphone or instrument accessory.
