1、Technical Specifications: Designed specifically for horns, drums, acoustical and electric guitars, the N/D468 provides a smooth, natural sound, capturing the excitement of the instrument. The supercardioid pattern provides superior rejection and acoustic isolation in any application. An innovative E

2、V design harnesses the increased power of a neodymium based magnet design, allowing a large-diameter voice coil (up to 50% larger than other mics) for dynamic, efficient microphone performance. N/DYM offers the power and clarity to “cut through the mix.” Whatever your instrument application the N/D4

3、68 is sure to be a top performer. Operation The low frequency response of the N/D468 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

4、 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

5、 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. : tneme lEeru t c ur t stengamMYD/N c i manyD :eso lC,esnopseR.qerFzH000,22-zH03 : raF,es

Always point the microphone at the desired source of sound, and away from any unwanted sources. 2.The microph

13、one 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 mic

14、rophone 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 th

15、e placement of the microphone to gain optimal performance. UsageOptimal Placement Electric Guitar and Bass Guitar AmplifierPlace microphone approximately 1-2 from and at a 90degree angle to the speaker cone. To reduce boominess, move the microphone off axis to the cone from 90 to 45, or move mic fro

16、m center of cone to either edge. Tom-TomsOn double headed Toms place mic over the top of drum 1-3 and at a 45 angle to the drum surface and 1-2 in from the drum edge. On single headed Toms use above method or place mic inside Tom from underneath at a 90 angle from the center of head, 3-5, away. Snar

17、e DrumPlace mic 1-3 above the heads, 1-2 in from the rim. Aim each mic at the top heads angled down about 45. If the drum rings, tape deadening material to the head or use damping rings. For more “snare” sound place a 2nd mic underneath aimed up at the bottom of head. CymbalsPlace microphone one to two feet above the top of cymbals. High-HatPlace 5 inches above outside edge at a 45 down angle. Brass6-24 away, and on axis with the bell of the instrument. Acoustic GuitarPlace mic 6-12 from where finger board joins the body.
