Sennheiser SL Boundary 114-S DW-4 B — Wireless Boundary Microphone
SL Boundary 114-S DW-4 B Overview
The Sennheiser SL Boundary 114-S DW-4 B is a professional wireless table boundary microphone built for demanding installed sound environments including boardrooms, conference rooms, courtrooms, and houses of worship. Designed as part of Sennheiser’s SL Digital Wireless ecosystem, it delivers a half-cardioid pickup pattern optimized for table-surface placement, capturing speech from seated participants while rejecting unwanted off-axis noise. The wireless design eliminates cable runs across table surfaces, simplifying installation and maintaining a clean aesthetic in professional environments. This microphone is well suited for AV integrators, corporate facility managers, and system designers requiring reliable, discreet wireless audio capture.
The boundary form factor keeps the microphone low-profile on any conference table surface, and its integration into the SL Digital Wireless platform provides a managed, scalable wireless infrastructure for multi-channel installations.
