MICROPHONES — Installed Sound: Conference (part 1 of 2)
MB SERIES
Mini-Boundary™ Microphone System
Featuring an incredibly small size, the MB Series of Mini-Boundary, half-supercardioid
microphones from Crown offer a wide range of features and flexibility. The miniature,
low-profile designs virtually disappear when installed, yet provide the same great sound
as our highly-acclaimed PCC microphone series. Best of all, the MB Series provides
substantial savings compared to traditional microphones.
Comprised of five microphones—three that work with our innovative MB interfaces
and two that operate in a traditional stand-alone manner—the MB System lets you mix
and match microphones as needed for multiple configurations.
All MB System microphones feature a surface-mounted half-supercardioid capsule for
extended reach and clarity. Each microphone also features a built-in red LED that illu-
minates when the microphone is active.
The
MMBB--22
is a tiny, (less than 1 x 1.5-inch.) removable microphone
that features a 1/4-inch stereo phone plug for quick insertion and
removal from a standard contractor-supplied jack. Like the MB-1 and
MB-4E, the
MMBB--22
features multiple switching modes when used with
an MB Interface.

Just 1.3 in. wide! The low-profile MB-1 features a ¼-in. stereo
phone plug for quick insertion and removal from the supplied
insert. The insert, featuring a black anodized aluminum finish, can
be permanently installed, and includes a black dust cap for use
when the microphone is removed. In combination with an MB
Interface, the MB-1 can be programmed for multiple switching
functions.
