Shure MX412D / C conference microphone

Shure MX412D / C conference microphone Shurt MX412D / C Goose neck spokes newly explained flexible real connotations. In addition to the fully adjustable gooseneck, there are more flexible new interchangeable capacitive microphones. The interchangeable microphone head has a design that is easy to replace, and can use heart-shaped, super-interested, and all-to-direction patterns that provide ultra-wide frequency response and precision for a variety of applications (such as churches, courts and conference centers). Sound reproduction. In addition, the capacitive microphone head is suitable for each model of the new MicroFlex product line, making it easier to use and has a sound quality consistent. Shtrian MX412D Shuur MX412D / C contains a unique Switch with LEDs with LEDs. And the MX412D / C gooseqi cylinder has high sensitivity and a balanced output without a transformer, which can improve the immunity to electromagnetic alternating symbols and radio frequency interference, even by a long distance cable transmission. Shuur MX412DC = Heart Shaped; s = superography; n = non-wrong cartridge product function: wider dynamic range and frequency response can be provided with an accurate recovery microphone head of the entire audio frequency spectrum to provide each application The pickup mode does not have a balanced output of the transformer, which can improve the immunity to noise when transmitting the long-distance cable transmission, can isolate more than 20 dB of noise lock flange brackets from surface vibration to be permanently securely secured. Placeable foam windshield on desktop, podium or conference table Programmable ON / OFF switch and ON / OFF LED LEDs new brighter LEDs improve visibility logic input / output connections in a strong lighting environment can be used Remote control or with automatic microphone mixer use technical parameters: microphone specification frequency response 50 to 17,000 Hz output impedance effective impedance is 180 ohm (EIA rated to 150 ohm) sensitivity (1,000 Hz, open circuit voltage) Heart shaped: -35.0 dBV / PA (17.8 mV) Super heart: -33.5 DBV / PA (21.1 mV) Over-direction: -27.5 DBV / PA (42.2 mV) 0 gain, all values are -12 dB; PA = 94 DB sound pressure level Press (1 kHz, 1% Total harmonic distortion, 1 kHz load) Heart shaped: 124.2 DB superography: 122.7 DB Over-direction: 116.7 DB0 Gain, all values are +6 DB equivalent output noise (A Weight) Heart Shaped: 28.0 dB Sound pressure grade super heart shaped: 26.5 dB Sound pressure level 全向: 20.5 DB Sound-resistance level signal to noise ratio (refer to 94 dB Sound pressure level) Heart shaped: 66.0 DB superography: 67.5 DB To: 73.5 DB1 Dynamic range 96.2 DB0 gain, 100 dB common mode suppression minimum 45.0 dB preamplifier output limit level (1% total harmonic distortion) -6.0 dBV (.5 V) 0 The positive voltage (relative to pin 3) is generated on the pin 2 of the -12 DBV polar diaphragm when gain. Power supply requirements 11 to 52 VDC, phantom, 2.0 MA environment requirements use temperature range: -18 to 57 degrees Celsius (0 to 135 degrees Fahrenheit) relative humidity: 0 to 95%
