Sennheiser SL DW TS 153 Set

The Sennheiser SL DW TS 153 Set is a professional wireless speech system designed for podium presentations, panel discussions, press events, lectures and educational spaces. The set includes the SL Tablestand 153-S DW, the MEG 14-40-L-II gooseneck microphone with LED ring, and the SL Rack Receiver DW – providing everything needed for stable, high-quality speech reinforcement.

The system operates in the license-free 1.9 GHz band and uses advanced algorithms for automatic frequency management and interference mitigation, delivering a continuous, noise-free signal without dropouts. Audio transmission is protected with AES-256 encryption, ensuring secure communication in corporate, governmental and institutional environments.

The tablestand supports both wireless charging and USB charging, includes battery level indicators and offers up to 10 hours of operation with the BA 40 battery. Remote monitoring and control via Sennheiser Control Cockpit allows real-time supervision of battery status, microphone settings, device state and system configuration.

The MEG 14-40-L-II microphone features a cardioid pickup pattern, high sensitivity and a bi-color LED ring for status indication. It operates via phantom power and includes RFI protection for reliable use in complex RF environments.

The included SL Rack Receiver DW ensures stable reception and offers XLR and RCA outputs, a 7-band EQ, voice presets, an OLED display and IPv4/IPv6 network control.

This is a complete, compact, mobile “plug-and-play” solution that enables high-quality speech reproduction in any space – even without permanent AV infrastructure.
