Sennheiser SL DW TS 133 Set

SL DW TS 133 Set is a complete wireless solution for presentations, lectures and meeting rooms, pairing a desktop tablestand with the MEG 14-40 gooseneck microphone and the SL Rack Receiver DW. It provides a fully professional speech setup with clean audio and zero cable clutter.

The system is built on SpeechLine Digital Wireless technology, ensuring stable RF performance, automatic frequency management and AES 256 encrypted transmission. The 133-S DW tablestand is designed specifically for speech and supports any Sennheiser XLR-3 gooseneck microphone – in this set it comes with the MEG 14-40 B, delivering natural, focused and highly intelligible voice pickup.

The tablestand operates on the BA 40 battery for up to 11 hours and supports both USB charging and wireless charging via the CHG 2W induction station. This allows quick setup and flexible placement without running cables across the room.

The included SL Rack Receiver DW offers advanced signal processing, EQ adjustments, low-cut filtering, speech presets for male/female voices, and full remote management via Sennheiser Control Cockpit. The system automatically optimizes sensitivity, selects the best frequency and ensures stable transmission without interference.

This kit is ideal for lectures, panel discussions, public speaking, corporate meetings and any scenario requiring clear speech and the mobility of a wireless system.
