The CM10B 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. The CM10B 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. Although the CM10B is very small in size, all the electronics are contained within the body, eliminating the need for any external electronics pack. 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. The CM10B is built using heavy-duty die cast construction with reinforced steel grill screen. Convenient mounting holes and hardware for hanging on walls or ceilings is included. A low reflectance, matte black finish enhances the stylish minimalist look.
