GENERAL

Shure Microflex

MX300 Series microphones are surface-

mounted electret condenser microphones designed primarily

for mounting on conference tables, stage floors, and lecterns.

Their high sensitivity and wide frequency range make them es-

pecially suitable for picking up speech and vocals in sound re-

inforcement and recording applications. Interchangeable car-

tridges provide the installer with greater flexibility and make it

possible to easily reconfigure microphone coverage as the

need arises. The MX392 and MX393 models include an inter-

nal preamplifier .

MX300 Series microphones take advantage of the princi-

ple that, at a barrier or boundary, the sound pressure level

doubles. When placed near a sufficiently large boundary

surface, the microphone has 6 dB higher sensitivity and

approximately 3 dB greater direct-to-reverberant sound ra-

tio.

FEATURES

· Flat frequency response across the vocal range for un-

colored sound

· Interchangeable cardioid, supercardioid, and omni-

directional cartridges that provide choices for applica-

tions

· Sleek, low-profile design for unobtrusive appearance

· Balanced transformerless output for increased immunity

to noise over long cable runs

· Low susceptibility to electromagnetic hum and RFI

· Programmable on/off switch and LED on/off indicator

· Logic input/output terminals for remote control or use

with automatic mixers (MX392 models only)

MODEL VARIATIONS

· MX392 Models: Surface-mount microphone; in-

cludes a programmable membrane on/off switch, log-

ic input/output ter minals, an on/off indicator LED,

screw terminal connections, and attac hed untermi-

nated cable.

· MX393 Models: Surface-mount microphone; in-

cludes a pr ogrammable membrane on/off switch, an

on/off indicator LED, and a miniatur e, three pin con-

nector.

Selecting a Cartridge

All Micr oflex mic rophones are available with any one of

three interchangeable cartridges . The polar pattern of the

original cartridge used in a particular microphone is indi-

cated by the model number suffix:

C = Cardioid, S = Superc ardioid, O = Omnidirec tional

Cardioid (C). Recommended for general sound rein-

forcement applic ations. Pic kup angle (-- 3 dB) = 130°.

Supercardioid(S).Recommendedfor sound reinforc e-

ment applications requiring narrow or more distant c over-

age. Picku p angle (-- 3 dB) = 115°.

Omnidirectional (O). Recommended for recording or

remote monitoring applications . Pickup angle (--3 dB) =

360°.

MICROPHONE PLACEMENT

To maintain the flattest possible low-fr equency re-

sponse and optimum rejection of backgr ound noise, place

the microphone on a flat s urface that is as large as pos-

sible. The s urface can be a floor, t able, or lec tern.

NOTE: Avoid locating micr ophones near reflectiv e sur-

faces other than the boundary sur face (i.e., beveled sides

of pulpits or overhanging shelv es). Failure to do so will re-

sult in inc reased levels of rev erberant sound.
