CM11B OMNI-DIRECTIONAL BOUNDARY MIC
SERIES CATEGORY
INSTALLATION MICS BOUNDARY MICS
GENERAL DESCRIPTION
The CM11B 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 that microphone to be used in
applications where low visibility is desired. The CM11B
features a permanently charged condenser element
with an 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 electronics 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 bottom 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 hardware for hanging on walls or ceilings
is included. A low reflectance, matte black finish
enhances the stylish minimalist look.
