Electro Voice

The N/D767a presents optimal performance in a live sound environment. The 767a vocal microphone utilizes
EV’s VOB™ (Vocally Optimized Bass) technology to provide the performer with reduced low-end distortion
and eliminates the muddiness found in other microphones. Combined with EV’s industry first
neodymium based magnet structure, the N/D767a offers the power and clarity to cut through the mix.
Operation
The low frequency response of the N/D767a 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-talked, 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.
