Shure KSM32 Operation, Power, Mounting, Integral Pop Filter, Selecting Low-Frequency Response

OPERATION

Position the microphone so that the side marked ªShureºÐthe side opposite the switchesÐfaces the sound source.

Power

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.

Mounting

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.

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.

Integral Pop Filter

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.

Selecting Low-Frequency Response

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.

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.

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 ªmuddy.º

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.
