Microflex￿ MX300 Series User Guide

Boundary Microphones

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 terminals, an on/off indicator LED, screw terminal connections, and attached untermi- nated cable.

￿MX393 Models: Surface-mount microphone; in- cludes a programmable membrane on/off switch, an on/off indicator LED, and a miniature, three pin con- nector.

Selecting a Cartridge

All Microflex microphones 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 = Supercardioid, O= Omnidirectional

Cardioid (C). Recommended for general sound rein- forcement applications. Pickup angle (--3 dB) = 130￿.

Supercardioid (S). Recommended for sound reinforce- ment applications requiring narrow or more distant cover- age. Pickup 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-frequency re- sponse and optimum rejection of background noise, place the microphone on a flat surface that is as large as pos- sible. The surface can be a floor, table, or lectern.

NOTE: Avoid locating microphones near reflective sur- faces other than the boundary surface (i.e., beveled sides of pulpits or overhanging shelves). Failure to do so will re- sult in increased levels of reverberant sound.

MX300 Series specifications

The Shure MX300 Series represents a significant advancement in professional audio technology, designed specifically for the nuances of theatrical performances, live events, and studio recording. These high-quality microphones are engineered to deliver exceptional sound clarity and reliability, making them an essential tool for audio professionals.

One of the standout features of the MX300 Series is its versatile capsule design. The microphones utilize a proprietary cardioid pattern that effectively isolates the desired sound source while minimizing ambient noise from the surrounding environment. This directional sensitivity makes them ideal for stage use, where managing feedback and unwanted sound is crucial.

The MX300 Series incorporates advanced audio technologies, including integrated pop filters and shock mounts. These features help to reduce plosive sounds and vibrations that can detract from vocal performances. The result is a cleaner, more focused sound with less interference, allowing performers to project their voices confidently.

Durability is another hallmark of the MX300 Series. The microphones are constructed with a robust metal chassis designed to withstand the rigors of touring and frequent use. The rugged design ensures that the MX300 can handle the demands of both outdoor and indoor environments without compromising audio quality.

In addition to its physical durability, the MX300 Series boasts impressive frequency response characteristics. The microphones are engineered to capture a wide range of frequencies, from the rich lows of a deep bass voice to the sparkling highs of a soprano. This broad frequency range allows for a natural and accurate representation of the performer's voice, enhancing the overall listening experience.

The MX300 Series also features an intuitive user interface with convenient controls, making it easy for audio engineers to adjust settings on the fly. This level of user-friendly design ensures that both seasoned professionals and newcomers to the audio field can operate the microphones without extensive training.
