  • SL Boundary 114-S DW-4 B Wireless Boundary Microphone

    Part of the SpeechLine Digital Wireless line of microphone conferencing systems, the Sennheiser SL Boundary 114-S DW-4 B is a wireless boundary microphone optimized for speech transmission in conference rooms, huddle rooms, and meeting spaces. Designed to be placed on a flat surface such as a desk or a conference table, its flat shape is visually unobtrusive for the seated meeting participants. The microphone is equipped with a cardioid polar pattern that picks up the speaker either in front of the mic or in close proximity, ideal for meetings, presentations, video conferencing, streaming, and more.

    The SL Boundary 114-S DW-4 B is powered via the included BA 40 rechargeable battery pack, which provides a typical operating time of 13 hours on a full charge. The complete absence of cable gives you speed of setup and the freedom to position the mic anywhere in the room. The battery can be charged wirelessly with the CHG 2W wireless power transmitter (available separately) or via USB.

    Compatible with the SL Rack Receiver DW stationary receiver, the SL Boundary 114-S DW-4 B can be monitored and controlled remotely with the free Sennheiser Control Cockpit software (available separately).
