The Sennheiser SL-TS 133 GN SET DW-4 US is a comprehensive wireless conference table microphone system designed for professional meeting rooms, boardrooms, and council chambers. This set provides a complete, integrated solution for clear audio capture and transmission in collaborative environments. The core of the system is a fixed, gooseneck microphone base station that houses a wireless transmitter and is designed to be discreetly installed on a table surface, with an attached flexible gooseneck allowing for precise positioning of the microphone capsule. This setup ensures consistent, high-quality audio pickup for participants seated around the table, facilitating natural conversation and clear transcription without the clutter of individual wired microphones or the need for a central sound column.

The system operates on a stable UHF frequency band, utilizing a diversity receiver to ensure a robust and dropout-free wireless audio link between the table unit and the receiver, which can be conveniently rack-mounted at a distance. The microphone capsule itself typically features a uni-directional pickup pattern, such as cardioid or supercardioid, to focus on the speaker directly in front of it and reject ambient room noise and sounds from other directions. This directionality, combined with the close-proximity placement enabled by the gooseneck, provides excellent gain before feedback, allowing for higher system volume before acoustic feedback occurs—a critical feature in reverberant rooms with installed loudspeakers.

Functionality extends beyond simple audio capture. The table unit often incorporates intuitive user controls, such as a prominent push-button for muting and unmuting the microphone, accompanied by a highly visible LED status ring that clearly indicates the mute state to all participants. The system is designed for seamless integration with existing room audio systems, connecting via standard balanced XLR or line-level outputs. By offering a reliable, user-friendly, and aesthetically clean wireless solution, the Sennheiser SL-TS 133 set addresses the core needs of modern conferencing: providing clear, intelligible audio for both in-room reinforcement and remote participants via teleconferencing or video conferencing systems.
