OVERVIEW
Shure Microflex ^® MX400 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.
FEATURES
- Wide dynamic range and frequency response for accurate sound reproduction across the audio spectrum
- Interchangeable cartridges provide the right polar pattern for every application
•Balanced, transformerless output for increased immunity to noise over long cable runs - Shock mount that provides over 20 dB isolation from surface vibration noise
- Locking flange mount for permanently securing microphone to lecterns, pulpits, or conference tables
- Snap-fit foam windscreen
- MX418S: 457 mm (18 in) gooseneck microphone; includes a mute switch and an LED.
Dynamic Range at 1 kΩ Load
96.2 dB
100 dB at 0 gain
Common Mode Rejection 45.0 dB minimum
Mute Switch Attenuation (switched models only) 50.0 dB minimum
Preamplifier Output Clipping Level (1% THD) -6.0 dBV (0.5 V) -12 dB at 0 gain
Polarity
Positive sound pressure on diaphragm produces positive voltage on pin 2 relative to pin 3 of output connector.
Power Requirements
11 to 52 Vdc phantom, 2.0 mA
Environmental Requirements
Operating Temperature Range: -18^ to 57^ ( 0^ to 135^ )
Relative Humidity: 0 to 95%
Dimensions (Figure 3)
Certification
Eligible to bear CE Marking. Conforms to European EMC Directive 89/336/EEC. Meets applicable tests and performance criteria in European Standard EN55103 (1996) parts 1 and 2, for residential (E1) and light industrial (E2) environments.
