The new “vocally optimized bass” or VOB technology provides the performer 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 vocal clarity. The increased clarity permits greater working distances than other competitive microphones, and ensures a clean, clear, consistent sound that “cuts through the mix.” Operation The low frequency response of the N/D267a and 267as 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 systems sensitivity to feedback caused by sound entering the microphone from the loudspeakers.

Instrumental Microphone Standard Placement & Use Guidelines 1. Always point the microphone at the desired source of sound, and away from any unwanted sources. 2.The microphone should be located close to the sound source to minimize interference from other potential sound sources. 3. Use the 3-to-1 rule when using multiple microphones. Place each microphone three times farther from other microphones as from the desired sound source. 4. Minimize over-handling of the microphone to reduce unwanted mechanical noise. 5.Working close to the microphone will increase the bass tone and also provide increased gain-before-feedback. Microphone Use and Placement Please note that micing techniques are a matter of personal preference. These are merely guidelines to assist in the placement of the microphone to gain optimal performance. UsageOptimal Placement VocalsZero to six inches from the windscreen, and on axis with the microphone. Spoken WordFive to ten inches from the windscreen, and on axis with the microphone.
