Sennheiser SL Lavalier Set DW-4-US R - Wireless Lavalier System - 5...
Product Overview
The Sennheiser SL Lavalier Set DW-4-US R is a complete SpeechLine Digital Wireless lavalier microphone system for presentation, house of worship, and commercial meeting space applications. It bundles the discreet MKE 1 omnidirectional lavalier with the SL Bodypack DW transmitter and a rack-mount receiver, delivering hands-free wireless speech capture with automatic frequency management for AV integrators.
Product Description
Operating in the license-free 1.9 GHz band, the system requires no frequency license or registration and uses Automatic Frequency Management to continuously find a clear channel. That removes manual coordination for IT and facilities teams running wireless microphone systems across multiple boardrooms, training rooms, and all-hands rooms.
The included MKE 1 condenser lavalier reproduces clear, natural speech while staying visually discreet on presenters and clergy. The SL Rack Receiver DW and GA 4 rack-mount kit support clean equipment-rack integration, and the BA 30 rechargeable battery provides up to 15 hours of operation for full-day events and services.
