Sennheiser SpeechLine DW Boundary Microphone Set – SL Boundary Set DW-4 EU

The Sennheiser SL Boundary Set DW-4 EU is a cable-free boundary microphone set for conference rooms, built around the SL Boundary 114-S DW microphone and the SL Rack Receiver DW. It offers a 40 to 20,000 Hz frequency response, cardioid and half-cardioid pickup, and wireless inductive charging. Procure.ae supplies the SL Boundary Set DW-4 EU in the UAE.

The SL Boundary 114-S DW microphone is optimized for speech transmission in conference rooms and works without cables. Its signal-to-noise ratio is above 90 dB(A), its microphone sensitivity is 10 mV/Pa, and total harmonic distortion is typically 0.1 %. The rechargeable 2.2 Ah battery pack has a typical operating time of 13 hours. Dedicated battery status LEDs give a clear battery life indication, and the microphone can be charged wirelessly by inductive charging or via USB.

The set suits meeting rooms that need cable-free microphones on a table. It includes the SL Rack Receiver DW and everything needed for usage and installation, and all devices can be monitored and controlled remotely with the Sennheiser Control Cockpit. The SL TS 133 GN Set DW-3 is the tablestand option in this range, with a gooseneck microphone for podium speakers, so the boundary set suits open discussion around one table.
