WIRED MICROPHONES

CROWN

MB SERIES

602

Mini-Boundary Microphone System

With their incredibly small size, the MB Series offers a wide range of options

and flexibility—making boardroom installations much easier. Using

miniature, low-profile designs, these mini-boundary,

supercardioid mics virtually disappear when installed, yet provide the

same great sound as Crown’s highly-acclaimed PCC microphone series

at a substantial savings compared to traditional microphones.

Designed with the help of leading audio consultants and contractors, the

MB Series is a comprehensive system of microphones and electronics that’s

perfect for a wide range of applications. Comprised of five microphones—

three that work with the innovative MB-100 and MB-200 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.

Designed to accommodate up to four microphones, the MB interfaces provide four separate inputs, outputs and

programmable switching connections. With easy-hookup Phoenix connectors and a low profile, the MB interface mounts

quickly and conveniently beneath a tabletop. All MB System microphones feature a surface-mounted supercardioid cap-

sule for extended reach and clarity and a built-in red LED that illuminates when the microphone is active.

The MB-1, MB-2, MB-3 and MB-4 are each designed for multi-miking applications such as teleconferencing, distance

learning, boardrooms, and courtrooms. The MB-3 can also be used for surveillance in security applications, and the MB-4

in TV or theatrical applications.

grammed for touch-on/touch-off,

momentary on, or momentary off

(not on MB-3)

MB SYSTEM ELECTRONICS INTERFACE

The MB-100 and MB-200 are

electronic interfaces that power up to

four Crown mini-boundary MB-1,

MB-2, or MB-4/E microphones.

Interfacing up to four mics reduces

the size and cost of the mic system

and reduces installation time.

The MB-100 provides programmable

switching to turn the mic on or off if

desired (switches not provided). The MB-200 is the same plus it also has remote switch sensing

via an optical coupler.

Two microphones can be wired to each pluggable terminal block, which plugs into the MB-100

or MB-200. Pluggable terminal blocks are also provided for the balanced outputs on the

interface, and for remote switch sensing. They are powered by 18 to 48v phantom power from

a mixer or a phantom power supply.
