Description
MX392 and MX393 Microflex® Wired Boundary Microphones from Shure are equipped with features like programmable, silent membrane switches, logic inputs and outputs, and green LED indicators. The high-quality solution for a range of applications such as altars, boardrooms and distance learning centers, Microflex Boundary microphones feature interchangeable condenser cartridges.
MX392: Surface-mount mic; LED logic input/switch logic output terminals, screw terminal connections, attached unterminated cable
Features
- Flat frequency response across the vocal range for uncolored sound
- Interchangeable cardioid, supercardioid, and omnidirectional cartridges that provide optimal choice for each application
- Sleek, low-profile design for unobtrusive appearance
- Balanced, transformerless output for increased immunity to noise over long cable runs
- Programmable membrane on/off switch plus LED on/off indicator
- LED logic input and switch logic output terminals for remote control or use with automatic mixers (MX392 models only)
| Frequency Response | 50 to 17,000 Hz |
| Polar Pattern | Omnidirectional (MX392/O, MX393/O) |
| Output Impedance | EIA Rated at 150 ohms (180 ohms actual) |
| Sensitivity (at 1 kHz, open circuit voltage) | Omnidirectional: -22.0 dBV/Pa (79.4 mV) 1 Pascal=94 dB SPL |
| Maximum Sound Pressure Level (1 kHz at 1% Total Harmonic Distortion, 1 k ohm load) | Omnidirectional: 111.5 dB |
| Signal to Noise Ratio (referenced at 94 dB SPL) | Omnidirectional: 76.5 dB |
| Equivalent Output Noise (A-weighted) | Omnidirectional: 17.5 dB SPL |
| Dynamic Range | 94.0 dB |
| Common Mode Rejection | 45 dB minimum, 10 Hz to 100 kHz |
| Switch Attenuation | 50 dB minimum |
| Preamplifier Output Clipping Level | -6 dBV (0.5 V) |
| Polarity | Positive sound pressure on diaphragm produces positive voltage on pin 2 relative to pin 3 of output connector. |
| Logic Connections (MX392 Only) | LED IN: Active low (<1.0v), TTL compatible. Absolute maximum voltage: -0.7V to 50V. SWITCH OUT: Active low (<0.5V), sinks up to 20mA, TTL compatible. Absolute maximum voltage: -0.7V to 24V (up to 50V through 3 k ohms). |
| Power Requirements | 11 to 52 Vdc phantom 2.0 mA current consumption |
| Environmental Requirements | Operating Temperature Range: -18 to 57 degrees C (0 to 135 degrees F) Relative Humidity: 0 to 95% |
