RadioFans.CN 收音机爱 好者资料库 SHURE MODEL BG?6.1 CARDIOID DYNAMIC INSTRUMENT MICROPHONE The BG6.1 is
3、a high output, dynamic, instrument mi- crophone designed for professional sound reinforcement and project studio recording applications. Its dynamic car- tridge features a smooth, extended frequency response ideal for instrument miking, and a neodymium magnet for high output level and signal-to-nois
4、e ratio. The BG6.1 also maintains a consistent cardioid pattern throughout its fre- quency range, which ensures high gain-before-feedback, maximum isolation from undesired sound sources, and minimum off-axis sound coloration. The built-in, locking stand adapter is designed for easy and convenient po
5、si- tioning and installation. Its rugged construction, dent- resistant tapered grille, sturdy die-cast handle, and superi- or shock-mounting system allow the BG6.1 to maintain its high performance through even the roughest environ- ments. Typical BG6.1 applications include close miking of tom-toms a
6、nd other percussion instruments, as well as guitar amplifiers, brass instruments, and woodwinds. The BG6.1 can also be mounted on a stand for vocal applica- tions. GENERAL RULES FOR MICROPHONE USE 1. For optimal signal-to-noise ratio, place the microphone as close as possible to the desired sound so
7、urce. 2. For the best gain-before-feedback and isolation from undesired background noise, aim the microphone to- ward the sound source and away from undesired sound sources (see Figure 1). The BG6.1 features a cardioid polar pattern which is most sensitive to sound directly in front of the microphon
8、e, and least sensitive to sound directly at 180?. 3. For the purest reproduction of sound, use only one mi- crophone per sound source and use the fewest number of microphones necessary for the application. 4. For maximum isolation, keep the distance between mi- crophones at least three times the dis
9、tance from each source to its microphone. 5. Placing the microphone close to the sound source im- proves bass response (Figure 2). This phenomenon is known as proximity effect and can be used to achieve a fuller sound, and to change the bass output of an in- strument without using tone controls. Pro
10、ximity effect is also especially good for vocals during soft passages where emphasis is needed. 6. Placing the microphone too close to acoustically reflec- tive (smooth, hard) surfaces will result in a poor frequen- cy response and will increase the chances for feed back. To minimize this effect, pl
11、ace microphones as far as possible from acoustically reflective surfaces. 7. Add an external windscreen when using the micro- phone outdoors to reduce wind noise. 8. It is important to keep foreign particles out of the grille and the windscreen because they may alter the fre- quency response of the
12、microphone. The grille may be periodically cleaned using warm, soapy water. Rinse with plain water and let it dry before replacing.
