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

Give performers the flexibility to choose how they connect with their audience using the Galaxy Audio CSL4-HHBBP 4-channel digital UHF diversity wireless system, a versatile package combining two handheld microphones and two bodypack transmitters for live performances, houses of worship, presentations and professional productions. Operating within the 470–507MHz UHF frequency range, the system includes two HH48P handheld transmitters with dynamic cardioid capsules, two MBP48P bodypack transmitters and a rackmount CSL4 receiver with four independent True Diversity channels. This configuration provides two ready-to-use handheld microphones for vocals and spoken-word applications while allowing two additional performers to connect compatible headset microphones, lavalier microphones or instrument accessories to the bodypack transmitters. With 32-bit encrypted digital modulation, less than 3ms latency and an operating range of up to 300', the CSL4-HHBBP 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. Microphones and instrument accessories for the bodypack transmitters are not included and must be purchased separately.

Two Handheld Microphones and Two Bodypacks Support Versatile Performance Setups

The CSL4-HHBBP includes two HH48P handheld wireless transmitters and two MBP48P bodypack transmitters, providing a balanced configuration for productions requiring both traditional microphone operation and customizable wireless connections. The handheld microphones feature dynamic cardioid capsules designed to emphasize the primary sound source while reducing unwanted background pickup, making them suitable for vocal performances, announcements and presentations. The two bodypack transmitters accommodate compatible headset microphones, lavalier microphones or instrument connections, allowing users to select accessories that match their specific performance needs. This flexibility makes the system particularly useful for worship teams, theatrical productions, educational presentations and live events combining multiple audio sources. All four transmitters operate through independent wireless channels, allowing two handheld users and two bodypack users to perform simultaneously. Bodypack microphones and instrument connection accessories are sold separately, giving users the freedom to configure those channels according to their 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 further supports clear reproduction of vocals, instruments and spoken-word audio across all four channels.

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

Each of the CSL4-HHBBP'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 two handheld microphones and two bodypack sources without applying identical tonal adjustments to every channel. The rackmount receiver provides four balanced 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 format simplifies integration into portable sound systems, installed audio racks and professional mixing environments. Combining two handheld microphones, two customizable bodypack channels, intelligent wireless coordination and independent audio processing, the Galaxy Audio CSL4-HHBBP 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.
