Permanent Installation - Shure MX300 Serie Guia Del Usuario

MX392-MX392BE-MX393
Boundary Microphones
Shure Microflex MX300 Series microphones are surface-mounted electret condenser microphones
®
designed primarily for mounting on conference tables, stage floors, and lecterns. Their high sensi-
tivity 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 internal preamplifier.
MX300 Series microphones take advantage of the principle 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 ratio.
Features
The MX392, MX392BE, and MX393 feature pro-
grammable logic input and output. Additionally
they provide following benefits:
• Flat frequency response across the vocal
range for uncolored sound
• Interchangeable cartridges that provide a
choice of polar pattern for each application
• Sleek, low-profile design for surface mounting
• Programmable mute button
• LED indicator
• Logic input/output for remote control or use
with automatic mixers
• RF filtering
Model Variations
MX392: Attached, unterminated cable.
MX392BE: Attached, unterminated cable
configured at the factory for bottom exit.
MX393: Detachable cable with XLR output
connector.
The polar pattern of the included cartridge is
indicated by a model number suffix:
/C Cardioid
/S Supercardioid
/O Omnidirectional
/N Cartridge not included

Permanent Installation

MX392 and MX393
1. Remove grille to access mounting key holes.
2. Cut slots into pads.
3. Slide microphone forward to engage screws
in slots.
Note: If using rear side-exit cable option, only
drill two outer holes.
Microphone Placement
For best low-frequency response and rejection
of background noise, place the microphone on
a large, flat surface, such as a floor, table, or
lectern.
To reduce reverberance, avoid reflective sur-
faces above or to the side of the microphone,
such as beveled sides of pulpits or overhanging
shelves.
