Engineered for boardrooms and conferencing spaces where cable-free flexibility is essential, this wireless boundary microphone delivers optimized speech intelligibility for seated speakers. The half-cardioid polar pattern minimizes rear noise pickup while capturing focused audio from presenters positioned in front of the unit. Integrators gain programmable button modes—push-to-talk, push-to-mute, toggle, or permanent-on—to match client workflow requirements without additional hardware.

Inductive charging eliminates USB dependency during events, while compatibility with SL Rack Receiver DW ensures unified system management across multi-room installations. Real-time battery monitoring through dedicated status LEDs prevents unexpected dropouts, and Sennheiser Control Cockpit integration allows technicians to adjust settings and monitor performance from a central location. The compact footprint fits discreetly on conference tables without obstructing sightlines or requiring permanent mounting hardware.
