Electro Voice Microphone N D478 User Manual

N/D478  
N/DYM® Dynamic Cardioid  
InstrumentalMicrophone  
Key Features:  
VOBTM technology provides tailored bass  
response for controlled “proximity effect” and  
exceptional vocal clarity  
Cardioid pattern for superior feedback rejec-  
tion and acoustic isolation  
Excellent choice for micing acoustical or  
electrical instruments whether in a live sound  
or studio environment  
Neodymium based magnet structure pro-  
vides greater sensitivity and signal-to-noise  
ratio  
Warm GripTM handle for more comfortable feel  
and lower handling noise  
General Description:  
Technical Specifications:  
The N/D478’s acoustic response presents optimal  
performance in both a live sound or studio environment.The  
new “vocally optimized bass” or VOB™ technology provides  
the instrumentalist with reduced resonant distortion at low  
frequencies. Critical damping of the low frequency resonant  
peak has resulted in a microphone that replaces the  
“muddiness” found in competitive models with greater  
warmth and increased clarity. The result is a exceptional  
performing instrument microphone with clean, clear,  
consistent sound that “cuts through the mix.”

The low frequency response of the N/D478 microphone  
varies with the distance from the sound source. Known as  
“proximity effect,” maximum bass response is produced in  
“close-up” use with the microphone 1/4 inch from the sound  
source. Normal bass response is experienced with working  
distances greater than 24 inches.Working close to the  
microphone will produce a more robust sound. Close up  
positioning of the microphone will also reduce the potential  
for feedback from the sound reinforcement system.When  
close-miced, the bass-boost provides an increase in overall  
microphone output level.The mixer gain may be  
proportionately reduced, resulting in a reduction of the  
system’s sensitivity to feedback caused by sound entering  
the microphone from the loudspeakers.
