Introduction
Thank you for purchasing the CM11B boundary microphone from Samson Audio! The CM11B is a low profile, sur-
face-mount boundary microphone ideal for flat surfaces like conference room tables, alters or hanging on walls.
The minimally intrusive design allows that microphone to be used in applications where low visibility is desired. The
CM11B features a permanently charged condenser element with a half-omnidirectional pickup pattern. Because the
CM11B is omni-directional, it provides linear pick-up in a 360-degree pattern, allowing the unit to be placed on the
center of a conference table to pick-up everyone seated. Although the CM11B is very small in size, all the electron-
ics are contained within the body, eliminating the need for any external electronics pack. The CM11B is fitted with
a standard 3-pin miniature male XLR connector, and a 30-foot mini XLR to standard XLR cable is included. The
CM11B operates on standard 9 through 52 Volt phantom power. A heavy Neoprene rubber pad is added to the bot-
tom of the unit to decouple the microphone from the surface helping reduce unwanted pick-up noise. The CM11B is
built using heavy-duty die cast construction with reinforced steel grill screen. Convenient mounting holes and hard-
ware for hanging on walls or ceilings is included. A low reflectance, matte black finish enhances the stylish minimalist
look.
Should your CM11B Boundry Microphone ever require servicing, a Return Authorization number (RA) must be
obtained before shipping your unit to Samson. Without this number, the unit will not be accepted. Please call
Samson at 1-800-3SAMSON (1-800-372-6766) for a Return Authorization number prior to shipping your unit. Please
retain the original packing material and, if possible, return the CM11B in its original carton and packing materials.
