Galaxy Audio CSL4-SSVVM 4-Channel Digital UHF Wireless Microphone System - Frequency CODE M3 516-558MHz

Not every wireless application calls for the same microphone solution, which is why flexibility is often the key to a successful system. The Galaxy Audio CSL4-SSVVM 4-channel digital UHF wireless microphone system combines four independent digital UHF True-Diversity wireless channels into a professional rackmount platform designed to support both headset and lavalier applications simultaneously. This configuration includes one CSL4 quad-channel receiver, two MBP48 bodypack transmitters paired with HS13-UBK-GAL headset microphones, two MBP48 bodypack transmitters paired with LV13-UBK-GAL lavalier microphones, antennas, power supply, combined-output cable and quick-start guide. Features such as auto frequency scanning, RF spectrum analysis, IR sync, customizable LCD displays and onboard 7-band EQ per channel help simplify setup while delivering dependable wireless performance for houses of worship, educational facilities, theaters, conference spaces and live presentations.

Four Channels of Professional Digital Wireless

The CSL4 receiver integrates four independent digital True-Diversity wireless channels into a compact 1U rackmount chassis designed for reliable operation in challenging RF environments. Operating within the M-Band frequency range of 520–554MHz, the system provides access to 1,360 selectable frequencies and supports up to 17 compatible systems simultaneously. Auto frequency scanning and the built-in RF spectrum analyzer streamline frequency coordination, while IR Sync allows transmitters to pair instantly with their assigned receiver channels. With less than 3 ms latency, 32-bit encrypted digital transmission and operating range up to 300', the system delivers secure, low-noise wireless audio for professional applications.

Headset and Lavalier Flexibility in One System

The two included HS13-UBK-GAL headset microphones provide a secure, hands-free solution ideal for active presenters, instructors, performers and worship leaders who require maximum freedom of movement. Their dual-ear wraparound design helps maintain consistent microphone placement during extended use. The two included LV13-UBK-GAL lavalier microphones offer a more discreet alternative for presenters, panel discussions and speaking engagements where low-profile visibility is preferred. Paired with the MBP48 bodypack transmitters, both microphone types benefit from adjustable gain settings, detailed LCD status displays and reliable digital wireless performance.

Built for Professional Installations and Events

The CSL4 receiver provides balanced XLR outputs for each channel along with a summed unbalanced 1/4" output for simplified integration into mixers and installed sound systems. Individual 7-band EQ processing on each channel allows quick tonal adjustments directly from the receiver, while customizable display colors make channel identification easy during operation. Designed for long-term flexibility, the system can be expanded with additional Galaxy Audio wireless accessories and antenna management solutions as requirements grow. Compact, scalable and highly adaptable, the CSL4-SSVVM delivers a versatile wireless platform for environments where both headset and lavalier microphone solutions are essential.
