GENERAL
Shure Microflex MX412D Series microphones are miniature
electret condenser gooseneck microphones with a desktop base
and attached 3 m (10 ft) cable. The desktop base allows these
microphones to be used in multi–purpose rooms where quick
set–up is required, or where permanent installation is impractical.
FEATURES
Wide dynamic range and frequency response for accurate
sound reproduction across the audio spectrum
Interchangeable cartridges that provide an optimal polar
pattern choice for each application
Balanced, transformerless output for increased immunity to
noise over long cable runs
Programmable on/off switch and LED on/off indicator
Logic input and output terminals for remote control or use
with automatic microphone mixers
Snap-fit foam windscreen
MODEL VARIATIONS
All Microflex microphones are available with any one of three
interchangeable cartridges. The polar pattern of the cartridge is
indicated by the model number suffix:
C = Cardioid, S = Supercardioid, O= Omnidirectional
MX412D/C: 304.8 mm (12 in.) cardioid desktop
mini–condenser, gooseneck–mounted microphone.
MX412D/S: 304.8 mm (12 in.) supercardioid desktop
mini–condenser, gooseneck–mounted microphone.
MX412D/O: 304.8 mm (12 in.) omnidirectional desktop
mini–condenser, gooseneck–mounted microphone.
SELECTING A POLAR PATTERN
Cardioid (C). Recommended for general sound reinforcement
applications. Pickup angle (–3 dB) = 130 .
Supercardioid (S). Recommended for sound reinforcement
applications requiring narrower or more distant coverage. Pickup
angle (–3 dB) = 115 .
Omnidirectional (O). Recommended for recording or remote
monitoring applications. Pickup angle = 360 .

User Guide
GENERAL INSTALLATION GUIDELINES
1.
Aim the microphone toward the desired sound source, such
as the talker, and away from any unwanted sound source,
such as a loudspeaker.
2.
Place the microphone cartridge within 15 to 30 cm (6 to 12
in.) of the desired sound source.
3.
Always use the supplied windscreen or the optional metal
windscreen to control breath noise.
4.
If four or more microphones will be open at the same time,
use of an automatic mixer, such as the Shure SCM810 or
FP410, is recommended to minimize feedback and noise.
MICROPHONE INSTALLATION
Securing a Microphone to a Mounting Surface (Figure 1)
1.
Install two No. 6 wood screws, 50.8 mm (2 in.) apart, on the
mounting surface.
2.
Place the key holes over the screw heads and push the
microphone into position. Adjust the height of the screws as
necessary to secure the microphone.
Installing the Foam Windscreen (Figure 2)
1.
Press the foam windscreen onto the microphone until it
snaps into the groove located below the cartridge.
2.
To remove the windscreen, spread the slot in its mounting
ring with a screwdriver or thumbnail and pull the windscreen
off carefully.
INTERNAL DIP SWITCH FUNCTIONS
All MX412D models have internal DIP switches that allow the
user to program the On/Off switch for a variety of applications. To
gain access to the DIP switches, remove the bottom plate.
LOGIC TERMINAL DEFINITIONS
LOGIC GND Terminal: Connects to the logic ground of an
automatic mixer, switcher, or other equipment. Can be modified
to prevent ground loops. Refer to the "MX412D Logic
Modifications" paragraph.
SWITCH OUT Terminal: Provides a TTL logic low (0 Vdc)
when the membrane switch is pressed. Provides TTL logic high
(5 Vdc) otherwise. This signal is available at all times for all
switch settings. The Switch Out function provides momentary
closure when S1 is Off and latching closure when it is On.
MX412D LOGIC MODIFICATIONS
Isolating Logic Ground from Audio Ground
1.
Remove jumper R40 from the top of the circuit board.
2.
Make sure LOGIC GND terminal connects to the logic ground
of the automatic mixer, switcher, or other equipment.
Changing SWITCH OUT Terminal to Always Momentary
To accommodate interface equipment requiring momentary
closure of the microphone (even when the desired microphone
function is latching on/off), proceed as follows:
1.
Remove R45 from the top of the circuit board.
2.
Reinstall R45 at location R46 on the top of the circuit board.
