The Galaxy Audio CSL4-BBBBP 4-channel digital UHF diversity wireless system provides four independent bodypack channels in a versatile package designed for theatrical productions, houses of worship, presentations and professional live sound installations. Operating within the 470–507MHz UHF frequency range, the system includes four MBP48P bodypack transmitters and a 1U rackmount receiver featuring four independent True Diversity channels. Each bodypack can accommodate compatible headset microphones, lavalier microphones or instrument connections, allowing users to customize their wireless setup for different performance requirements. With 32-bit encrypted digital modulation, an operating range of up to 300' and 1,480 selectable frequencies, the CSL4-BBBBP provides flexible wireless operation for multichannel applications. Individual seven-band EQ, color-changing LCD displays and intelligent frequency management tools provide convenient control over all four channels. Microphones and instrument connection accessories are not included and must be purchased separately.

Four Bodypack Transmitters Support Customizable Wireless Configurations

The CSL4-BBBBP includes four MBP48P bodypack transmitters, providing a flexible foundation for productions that require different microphone types or wireless instrument connections. Each transmitter accommodates compatible headset microphones, lavalier microphones or instrument accessories, allowing sound engineers to configure individual channels according to the needs of performers, presenters and musicians. A four-position line-to-mic input gain adjustment provides flexibility for matching different audio sources, while an integrated LCD display offers convenient access to transmitter status information. Each bodypack operates on two AA batteries and provides approximately eight hours of battery life, supporting extended rehearsals, presentations and live events. With RF output power of up to 10mW, the transmitters provide practical wireless mobility for performers moving throughout the venue. Because microphones are not included, users can select compatible accessories suited to their specific applications without purchasing unnecessary microphone configurations.

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 bodypack transmitter. Color-changing LCD displays provide convenient visual feedback during operation, while 32-bit encrypted digital modulation supports secure audio transmission across all four channels. Together, these features streamline wireless coordination for sound engineers, production teams and venues managing multiple wireless sources.

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

Each of the CSL4-BBBBP'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 multiple bodypack sources 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 four customizable bodypack channels, intelligent wireless coordination and independent audio processing, the Galaxy Audio CSL4-BBBBP provides a flexible foundation for venues and production teams that need dependable multichannel wireless performance with the freedom to select their preferred microphone and instrument accessories.
