APPLICATIONS


應用場合

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的一些典型應用場合。但是,麥克風的使用在很大程度上取決於個人趣味,除了下面列出的以外,KSM32還可能應用於其他多種場合。

  • 人聲——獨唱、背景、配音、播音
  • 聲學樂器——如鋼琴、吉他、鼓、打擊樂器、絃樂器等
  • 管樂器——銅管和木管
  • 低頻樂器——如低音提琴、電貝司、踢鼓
  • 吊挂麥克風——鼓和打擊樂器等
  • 合唱合奏——合唱隊或交響樂團
  • 室內周圍環境拾音——吉他放大器或鼓



當用麥克風拾取一個聲源時,現場聲學環境及麥克風的安置對所獲得的音響效果有很大影響。對於每個應用場合,可能需要對這些變化因素進行試驗,以獲得最佳的整體音響效果。


OPERATION


操作

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


麥克風的取向應使標有“Shure”的一邊,即與開關相對的一邊面向聲源。

Power


電源

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需要幻路電源。使用48伏直流電源(IEC-268-15/DIN 45 596)時可獲得最佳性能。該麥克風在電源電壓低至11伏直流時仍可工作。

Mounting


安裝

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轉座和彈性隔振墊提供安全的方式將麥克風固定到地板或麥克風吊臺上。當使用轉座時,加以內部隔振墊可提供良好的隔振作用。如欲進一步降低外部振動的影響,可採用彈性隔振墊。

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.


安裝麥克風時,很重要的是要把隔振墊或轉座上帶有螺紋的滾花鎖定把手牢固地擰到麥克風底座上的螺紋孔中,但不要擰得過緊。

Integral Pop Filter


集成式靜電噪音篩檢程式

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具有一個集成式靜電噪音篩檢程式,可除去大多數因風和呼吸所造成的靜電噪音。當麥克風很靠近演唱者時,可能需要加一個外部靜電噪音保護屏,使用一個低頻截頻濾波器也可能有效。

Selecting Low-Frequency Response


選擇低頻回應

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背後的一個三位元開關可用來調節麥克風的低頻回應,可利用低頻濾波器的設定來補償風噪音、室內噪音和臨近效應。

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.


平坦回應。在任何希望最自然地再現聲源的場合,可使用這一設定。麥克風將會再現超低頻,可能需要使用ShureLock彈性懸挂隔振墊來降低由麥克風支架傳輸過來的機械振動。

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.”


低頻截頻。80赫茲時,提供每八度18分貝的截頻。有助於消除舞臺上的嗡嗡聲或其他來自暖通空調(HVAC)系統的低頻室內噪音。還可用它來補償鄰近效應,或降低可使樂器聲音顯得沈悶或“拖泥帶水”的低頻部分。

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.


低頻上移。提供一個115赫茲時每八度6分貝的低頻上移濾波器。可用它來補償人聲或樂器的鄰近效應,或降低可使樂器聲音顯得沈悶或拖泥帶水的低頻部分。
