APPLICATIONS

应用场合

Some typical applications for the KSM32 are listed below. Microphone use, however, is largely a matter of personal taste. The KSM32 may be used for a variety of applications other than those listed.

  • Voice—solo, background, voice-over, broadcasting
  • Acoustic instruments—such as piano, guitar, drums, percussion, strings
  • Wind instruments—brass and woodwind
  • Low frequency instruments—such as double bass, electric bass, kick drum
  • Overhead miking—drums or percussion
  • Ensembles—choral or orchestral
  • Room ambience pick-up—guitar amplifier or drums
Both the acoustic environment and microphone placement have significant effects on the sound obtained when miking a source. You may need to experi-ment with these variables to achieve the best overall sound for each applica-tion.

下面列出了KSM32的一些典型应用场合。但是,麦克风的使用在很大程度上取决于个人趣味,除了下面列出的以外,KSM32还可能应用于其它多种场合。
  • 人声——独唱、背景、配音、播音
  • 声学乐器——如钢琴、吉他、鼓、打击乐器、弦乐器等
  • 管乐器——铜管和木管
  • 低频乐器——如低音提琴、电贝司、踢鼓
  • 吊挂麦克风——鼓和打击乐器等
  • 合唱合奏——合唱队或交响乐团
  • 室内周围环境拾音——吉他放大器或鼓

当用麦克风拾取一个声源时,现场声学环境及麦克风的安置对所获得的音响效果有很大影响。对于每个应用场合,可能需要对这些变化因素进行试验,以获得最佳的整体音响效果。

OPERATION

操作

Position the microphone so that the side marked “Shure”—the side opposite the switches—faces the sound source.

麦克风的取向应使标有“Shure”的一边,即与开关相对的一边面向声源。

Power

电源

The KSM32 requires phantom power. Optimal performance will be achieved when using a 48 Vdc supply (IEC-268-15/DIN 45 596). The microphone oper-ates with supplies as low as 11 Vdc.

KSM32需要幻路电源。使用48伏直流电源(IEC-268-15/DIN 45 596)时可获得最佳性能。该麦克风在电源电压低至11伏直流时仍可工作。

Mounting

安装

The ShureLock swivel mount and elastic shock mount provide a secure means of fastening the microphone to a floor or boom stand. When using the swivel mount, the internal shock mount provides good isolation. For greater reduction of noise from external vibrations, use the elastic shock mount.

ShureLock转座和弹性隔振垫提供安全的方式将麦克风固定到地板或麦克风吊台上。当使用转座时,加以内部隔振垫可提供良好的隔振作用。如欲进一步降低外部振动的影响,可采用弹性隔振垫。

It is important when mounting the microphone that the threaded, knurled locking grip on the shock mount or swivel mount is screwed securely onto the threads at the base of the microphone. Do not overtighten.

安装麦克风时,很重要的是要把隔振垫或转座上带有螺纹的滚花锁定把手牢固地拧到麦克风底座上的螺纹孔中,但不要拧得过紧。

Integral Pop Filter

集成式静电噪音过滤器

The KSM32 has an integral pop filter which provides excellent protection against most wind and breath noise. An external pop protection screen may be necessary when close-miking vocalists. The use of a low frequency cutoff filter may also be effective.

KSM32具有一个集成式静电噪音过滤器,可除去大多数因风和呼吸所造成的静电噪音。当麦克风很靠近演唱者时,可能需要加一个外部静电噪音保护屏,使用一个低频截频滤波器也可能有效。

Selecting Low-Frequency Response

选择低频响应

A three-position switch on the back of the KSM32 allows you to adjust the low-frequency response of the microphone. The low-frequency filter settings can be used to compensate for wind noise, room noise or proximity effect.

KSM32背后的一个三位开关可用来调节麦克风的低频响应,可利用低频滤波器的设定来补偿风噪音、室内噪音和临近效应。

Flat response. Use this setting for any application where you desire the most natural reproduction of the source. The microphone will reproduce ultra-low frequencies, and the ShureLock elastic-suspension shock mount may be required to reduce mechanical vibrations transmitted through the mi-crophone stand.

平坦响应。在任何希望最自然地再现声源的场合,可使用这一设定。麦克风将会再现超低频,可能需要使用ShureLock弹性悬挂隔振垫来降低由麦克风支架传输过来的机械振动。

Low-frequency cutoff. Provides 18 dB-per-octave cutoff at 80 Hz. Helps eliminate stage rumble or other low-frequency room noise such as that coming from heating, ventilation, or cooling (HVAC) systems. It may also be used to compensate for proximity effect or to reduce the low frequencies that can make an instrument sound dull or “muddy.”

低频截频。80赫兹时,提供每八度18分贝的截频。有助于消除舞台上的嗡嗡声或其它来自暖通空调(HVAC)系统的低频室内噪音。还可用它来补偿邻近效应,或降低可使乐器声音显得沉闷或“拖泥带水”的低频部分。

Low-frequency rolloff. Provides a 6dB-per-octave rolloff filter at 115Hz. Use this setting with vocals or instruments to compensate for proximity effect or to reduce the low frequencies that can make an instrument sound dull or muddy.

低频上移。提供一个115赫兹时每八度6分贝的低频上移滤波器。可用它来补偿人声或乐器的邻近效应,或降低可使乐器声音显得沉闷或拖泥带水的低频部分。
