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.
