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 especially suitable for picking up speech and vocals in sound reinforcement and recording applications. Interchangeable cartridges 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 ap- proximately 3 dB greater direct-to-reverberant sound ratio.

FEATURES

•Flat frequency response across the vocal range for uncolored sound

•Interchangeable cardioid, supercardioid, and omnidi- rectional cartridges that provide choices for applications

wSleek, 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

wLogic 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 unterminated 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 indicated 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.

This makes it especially suitable for situations with multiple speakers, as it minimizes interference from surrounding sounds.

The MX392/C and MX392/S models share many similarities but cater to different user needs. The MX392/C comes equipped with a connector specifically designed for connection to a variety of audio systems, making it a flexible choice for various installations. This model also features an integrated preamplifier, which enhances the microphone's sensitivity and overall performance. The MX392/S, on the other hand, is designed for use with Shure's wireless systems, allowing for a more mobile and dynamic setup without compromising on sound quality.

Both the MX392/C and MX392/S utilize Shure's proprietary technologies to deliver pristine audio quality. The microphones employ high-quality condenser elements that capture a broad range of frequencies, providing a natural sound that accurately represents the speaker's voice. Additionally, the microphones are constructed with rugged materials designed to withstand the rigors of professional use, ensuring durability and longevity.

Another notable feature of these microphones is their ease of installation and use. With a variety of mounting options, including desktop bases and flexible goosenecks, users can customize their microphone placement for optimal performance. The built-in LED status indicator on the MX392 models helps users ensure that the microphone is powered and functioning properly.

In summary, the Shure MX300, MX392/C, and MX392/S microphones combine cutting-edge technology, robust construction, and user-friendly design to provide exceptional audio performance for a range of professional applications.
