Product Overview +
Complete Wireless System for Educators and Executives
The Sennheiser SL Handheld Set DW is a comprehensive package designed to deliver professional-grade audio for high-stakes environments. By combining a stationary receiver with a premium handheld transmitter, this set provides everything needed to capture speech with absolute clarity. The included rackmount kit ensures a clean, professional installation in any server rack or media lectern, making it the ideal choice for universities and corporate boardrooms.
Intelligent Bi-Directional Technology
Unlike traditional systems that require manual tuning, the SpeechLine Digital Wireless system utilizes bi-directional communication between the transmitter and receiver. This allows the system to autonomously monitor the RF environment and switch frequencies invisibly if interference is detected. It eliminates the technical guesswork, providing a stable, secure, and encrypted connection that lets the speaker focus entirely on their audience.
Versatile Power and Charging
Reliability is at the core of the SL Handheld DW. The system features a robust rechargeable accupack that delivers a full 15 hours of operation, enough to power through the longest conferences. For added convenience, the unit is USB-rechargeable, allowing for quick top-ups via the included cable or standard charging ports, ensuring the system is always ready for the next session.
Networked Maintenance and Control
Managing audio across a large campus or corporate office is streamlined via the Sennheiser Control Cockpit software. This digital tool provides a birds-eye view of all your networked SpeechLine devices. You can monitor battery levels, adjust gain settings, or update firmware from a central location, significantly reducing the time and effort required for routine technical maintenance.
