1、Technical Specifications: The N/D868 is truly a top performer in any application. Whether in a live sound or studio environment, the N/ D868 is able to handle incredibly high sound pressure levels without distortion or overriding the input mixer. With a response specifically designed to “kick” the N

2、/ D868 can be used “as is”no additional EQ required. Electrovoice was the first to utilize the neodymium magnet structure, and it remains at the heart of our new N/DYM series of microphones. Experience the leader again for the first time and hear the difference. Operation The low frequency response

3、of the N/D868 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 clos

Then, the bass- boost provides an increase in overall microphone output level.The mixer gain may be proportionately reduced, r

Standard Placement & Use Guidelines 1. Always point the microphone at the desired sou

12、rce 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

13、 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 p
