Shure Microflex® MX400S Series microphones are miniature gooseneck-mounted electret condenser microphones designed primarily for speech and vocal pickup. They can be mounted on lecterns, pulpits, or conference tables. All models include a preamplifier and are available with interchangeable cardioid, supercardioid, or omnidirectional cartridges.
MX400 microphones are available with 305 mm (12 in.) or 457 mm (18 in.) goosenecks, with or without a mute switch. They are available in supercardioid, cardioid and omnidirectional polar patterns.
The polar pattern of the included cartridge is indicated by a model number suffix:
/N Cartridge not included
Microflex microphones use interchangeable cartridges that allow you to choose the polar pattern for different installations.
If necessary, the preamplifier gain can be reduced by 12 dB. Contact an authorized Shure service center for information.
Mount the microphone using one of the following methods.
@ 1 kHz, open circuit voltage
|Cardioid||–35 dBV/Pa(18 mV)|
|Supercardioid||–34 dBV/Pa(21 mV)|
1 Pa=94 dB SPL
1 kHz at 1% THD, 1 kΩ load
|Cardioid||28 dB SPL|
|Supercardioid||27 dB SPL|
Ref. 94 dB SPL at 1 kHz
1 kΩ load, @ 1 kHz
10 Hz to 100 kHz
45 dB, minimum
at 1% THD
–6 dBV (0.5 V)
Positive sound pressure on diaphragm produces positive voltage on pin 2 relative to pin 3 of output XLR connector
