The Electro-Voice Model RE38N/D
cardioid dynamic microphone

Description
The Electro-Voice Model RE38N/D is a professional quality dynamic cardi­oid micro­phone designed especially for recording, broadcast and sound reinforcement applications requiring smooth tailorable response over a wide frequency range. The extended high-frequency response and the 16-position equalization switch give the RE38N/D great flexibility in obtaining the appropriate sound for any situation. For those applications that require a deeper sound, the micro­phone has bass-boosting proximity effect when used up close. The amount of this proximity effect can be reduced by ad­justing the equalization switch as shown on the frequency response curves. The “brightness” of the high frequency response is also adjustable with the equalization switch.

The RE38N/D incorporates a revolutionary neodymium alloy magnet to provide high sensitivity. Combined with the inherent low noise of a dy­namic transducer, the high sensitivity ensures a superior signal-to-noise ratio ready for digital recording and sampling. To further reduce noise, the micro­phone uses a hum-bucking coil to attenuate from lighting and other sources. The RE38N/D utilizes DynaDamp, an advanced vibration-isola­tion material, so that a large external shock mount is not required for studio use. DynaDamp is a unique foamed elastomer, specially formulated for vibration control.

The dynamic element of the RE38N/D provides reliable operation in hu­midity and temperature extremes. An Acoustifoam pop filter reduces both wind noise and P-pop breath sounds. The micro­phone features a rugged machined aluminum case and Memraflex grille screen designed to with­stand all the rigors of professional use.

To solve the problem of micro­phone placement the RE38N/D features a pivoting yoke configuration. With the unique pivoting yoke, the micro­phone can be easily adjusted to position the front toward the sound source. The yoke positions are detented to assure the micro­phone doesn’t shift during usage. This adjustment option in combination with the stand adapter provides a highly flexible mounting system.

Using the Equalization Adjustments
The graphic pictorials on the RE38N/D nameplate provide an approxima­tion of the 16 possible far-field (distant) frequency responses which may be selected. This flexibility allows the user to obtain a desired sound character in almost any situation right at the micro­phone. There are eight low-frequency-tailoring combinations and two high-frequency combina­tions to yield a total of 16 possible frequency responses built into the RE38N/D. With these options, the user can compensate for proximity effect, low frequency noise and sibilance to get that “right sound.” The control is easy to adjust with a small screwdriver (provided) yet cannot be accidentally changed during use. Experimentation is encouraged with the equalization positions to get the performance best for your application. To aid in determining the frequency response which is right for your application, the typical responses for the positions are shown in Figures 1 through 16.

Switch position 1 yields the flattest frequency response of all the posi­tions to give a clean, uncolored representation of the input sound for signals in the far field. The far field response shown is the output when the sound source is at least 24 inches from the micro­phone grille. Low-frequency response increases due to proximity effect when the sound source is less than 24 inches from the micro­phone. This low-frequency response will continue to increase as the sound source moves closer to the micro­phone. The amount of proximity effect in the output of the micro­phone can be controlled by placing the micro­phone at different distances from the sound source and with the equalization choices provided in the RE38N/D. Positions 9 through 16 have the same low frequency shape as the respective positions 1 through 8, the difference being that high-end response is “bright” in positions 9 through 16.

The cardioid polar pattern of the RE38N/D provides excellent isolation
at all frequencies. The directional control is smooth in transition
from front to back to keep off-axis coloration at a minimum.
