Digital UHF Performance With Advanced RF Control

The CSL receiver combines digital UHF True-Diversity technology with practical RF management features that simplify setup and improve reliability. Auto frequency scanning quickly locates available channels, while the integrated RF spectrum analyzer provides a visual overview of local RF activity for easier frequency coordination. Operating within the M-Band frequency range of 520–554MHz, the system offers access to 1,360 selectable frequencies and supports up to 17 compatible systems operating simultaneously. With less than 3 ms latency and 32-bit encrypted digital transmission, the CSL-HS delivers clear, secure audio with minimal delay.

Hands-Free Headset Performance

The included HS13-UBK-GAL headset microphone provides a comfortable and secure hands-free solution for users who need unrestricted movement while maintaining consistent vocal pickup. Its dual-ear wraparound design helps keep the microphone positioned correctly during active presentations, performances and instructional sessions. Paired with the MBP48 bodypack transmitter, users benefit from adjustable input gain, LCD status monitoring and approximately eight hours of battery life from two AA batteries. The result is a dependable wireless system designed to keep presenters focused on their audience rather than their equipment.

Professional Connectivity and Installation Flexibility

The CSL receiver provides both balanced XLR and unbalanced 1/4" outputs for easy integration with mixers, powered speakers and installed audio systems. Built-in 7-band EQ allows quick tonal shaping directly from the receiver, while customizable display colors simplify identification in multi-system environments. Compact enough for mobile applications and supplied with a rackmount kit for permanent installations, the CSL-HS delivers professional wireless headset performance for houses of worship, schools, conference facilities, corporate AV systems and live event production.
