Sennheiser SL Handheld Set DW-4-US R - Wireless Vocal System - 505905
Product Overview
The Sennheiser SL Handheld Set DW-4-US R is a complete SpeechLine Digital Wireless handheld microphone system for presentation, house of worship, and commercial meeting space applications. Operating in the license-free 1.9 GHz band with automatic frequency management, this rack-mount wireless microphone system removes the frequency-coordination burden from AV integrators and IT teams managing multi-room deployments.
Product Description
The set pairs the SL Handheld DW transmitter and MME 865-1 supercardioid condenser capsule with the rack-mount SL Rack Receiver DW. The 1.9 GHz digital transmission is license-free and requires no registration, while Automatic Frequency Management continuously finds a clear channel, eliminating manual frequency planning across boardrooms and training rooms.
With up to 250 mW adaptive RF output and a 50 Hz to 20,000 Hz audio response, the system delivers reliable, intelligible speech for auditoriums and all-hands rooms. The included BA 10 rechargeable battery and GA 4 rack-mount kit support permanent installation, and the supercardioid capsule rejects off-axis noise for higher gain-before-feedback in live rooms.
