[. . . ] RE27N/D Variable-D® N/DYM® Dynamic Cardioid Microphone Key Features: · · · · · · Studio condenser performance from selfgenerating transducer Consummate announce microphone Ideal for sampling Switch-selected E. Q. [. . . ] The blast filter shall also serve as a shock mount for the internal microphone transducer. The microphone shall have a wide-range uniform frequency response from 45-20, 000 Hz. Integral passive networks, controlled with three recessed slide switches, shall be provided with switches in the "flat" position, the microphone shall be essentially flat from 80-2, 000 Hz with a 6-dB rise in response from 2, 000-16, 000 Hz. With one filter switch in the "roll-off" position, low-frequency response shall tilt down 6 dB from 250 to 100 Hz. A second filter switch, when in the "roll-off" position, shall have a gentle roll-off of 12 dB from 1, 000 to 100 Hz. The third filter switch, when in the "roll-off" position shall decrease the high-frequency rise by 3 dB. The open circuit voltage sensitivity shall be 3. 1 mV/Pascal at 1, 000 Hz and the power level sensitivity shall be -51 dB at 1, 000 Hz (0 dB equals 1 mW/ pascal. ) The magnetic circuit shall be a nonwelded circuit and employ a neodymium alloy magnet. The transducer shall employ a hum-bucking coil, with a resulting hum sensitivity of -130 dBm at 60 Hz in a 1 millioersted field, and a shield to prevent dust and iron particles from reaching the diaphragm.
