Samson Unidirectional Surface Boundary Mic - Black is a low profile, surface-mount boundary microphone ideal for flat surfaces like conference room tables, alters or hanging on walls. The minimally intrusive design allows the microphone to be used in applications where low visibility is desired. Features a permanently charged condenser element with a half-cardioid, or uni-directional, pickup pattern. The microphone exhibits excellent rear rejection, providing maximum gain before feedback. The CM10B is fitted with a standard 3-pin miniature male XLR connector, and a 30-foot mini XLR to standard XLR cable is included. The CM10B operates on standard 9 through 52 Volt phantom power. A heavy Neoprene rubber pad is added to the bottom of the unit to decouple the microphone from the surface helping reduce unwanted pickup noise. It is built using heavy-duty die-cast construction with reinforced steel grill screen. Convenient mounting holes and hardware for hanging on walls or ceilings are included. A low reflectance, matte black finish enhances the stylish minimalist look. • Surface mount Uni-directional boundary microphone • Condenser element • Half Cardioid Pickup Pattern • Internal Hi-pass filter • Mini XLR connector • Includes 30-foot cable with mini to standard XLR connectors • 9-52 Volt Phantom Power Operation
