SHURE INCORPORATED KSM32 CARDIOID CONDENSER MICROPHONE Thank you for selecting the KSM32 cardioid condenser microphone. Over 70 years of microphone manufacturing experience has contributed to making the KSM32 one of the finest condenser microphones available. If you have any questions not answered in this booklet, please contact Shure Applications at 847-866–2200, Monday through Friday, from 8:00 am to 4:30 pm, CST. In Europe, call 49-7131-72140. Our web address is www.shure.com. GENERAL DESCRIPTION The Shure KSM32 is a side-address, cardioid condenser microphone for highly critical studio recording and live sound productions. It offers an extended frequency response for an open, natural sounding reproduction of the original sound source. FEATURES Class A, transformerless preamplifier circuitry eliminates cross-over distortion for improved linearity across the full frequency range Embossed, high-compliance diaphragm provides extended low frequency response Ultra-thin, 2.5 m, gold-layered, low mass, Mylar diaphragm for excellent transient response 15 dB attenuation switch for handling extremely high sound pressure levels (SPL) Switchable low-frequency filter provides greater flexibility to reduce background noise or to counteract proximity effect Integrated three-stage pop protection grille reduces “pop” and other breath noise Internal shock mount reduces transmission of handling noise PERFORMANCE CHARACTERISTICS Extended frequency response Very low self noise Exceptional low-frequency reproduction High output level High input SPL capability No cross-over distortion Extremely uniform polar response Superior common mode rejection and suppression of radio frequency interference English – 1 MODEL VARIATIONS The KSM32/SL has a champagne-colored finish and comes with the following accessories: Locking aluminum carrying case ShureLock elastic-suspension shock mount ShureLock swivel mount Protective velveteen pouch The KSM32/CG has a non-reflective, charcoal-gray finish for situations where less microphone visibility is prefered, such as live sound and stage production. It comes with the following accessories: ShureLock swivel mount Padded, zippered carrying bag APPLICATIONS 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 experiment with these variables to achieve the best overall sound for each application. English – 2 OPERATION Position the microphone so that the side marked “Shure”—the side opposite the switches—faces 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 operates 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 microphone 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 “muddy.” 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. English – 3 Setting Attenuation The attenuation switch on the back of the KSM32 reduces the signal level from the cartridge by 15 dB without altering the frequency response. This can prevent extremely high SPL from overloading the microphone. To activate attenuation, move the switch to the “–15 dB” position. In situations where the high output capability of the KSM32 might overload the microphone preamplifier of a console or mixer, use an attenuation switch (pad) in the mixer or an external inline attenuator such as the Shure A15AS. Load Impedance A load impedance of at least 1000 Ω is recommended. When used with typical modern microphone preamplifiers (rated at about 2500 Ω), the KSM32 provides higher maximum SPL capability and output clipping level. The KSM32 can handle up to 160 dB SPL, and output +15 dBV into a 5500 Ω or greater load with microphone attenuation.
