GENERAL DESCRIPTION

The Shure®KSM32 is a side-address condenser microphone with a cardioid polar pattern.

Designed for studio use but rugged enough for live applications, the KSM32 has an externally

biased 1-inch diaphragm, extremely low self-noise, and an extended frequency response

specially tailored for vocal tracking and instrument recording.

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

The KSM32/CG has a non-reflective, charcoal-gray finish for situations where less micro-

phone visibility is preferred, such as live sound and stage production. It comes with the fol-

lowing accessories:

• ShureLock

™

Swivel mount

• Padded, zippered carrying bag

APPLICATIONS

Some typical applications for the KSM32 are listed below. Microphone use, however, is large-

ly a matter of personal taste. The KSM32 may be used for a variety of applications other than

those listed.

• Voice and vocals

• Close-miking of acoustic instruments such as piano, guitar, violins, drums, and

percussion

• Brass and woodwind instruments

• Low-frequency instruments such as double bass and kick drum

• Overhead miking for drums or percussion

• Orchestras, choirs, wind ensembles

• Room ambience pick-up (guitar amplifier or drums)

NOTE: Sound quality is strongly affected by microphone location and room acoustics. To

achieve the best overall sound for a particular application, it may be necessary to experiment

with microphone placement and various room treatments.

OPERATION

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 micro-

phone. Do not overtighten.

Power

The KSM32 requires phantom power and performs optimally with a 48 Vdc supply

(IEC-268-15/DIN 45 596). However, it will operate with slightly decreased headroom and

sensitivity with supplies as low as 11 Vdc. Most modern mixers provide phantom power.

Phantom power can only be transmitted to the KSM32 through a cable terminated with XLR

connectors at each end.

Positioning the Microphone

The front of the KSM32 is marked by the logo. See Figure 1. Position this side of

the microphone toward the sound source. The rear of the microphone is marked by the

logo, the low-frequency filter switch, and the 15dB attenuation switch.

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 reduce wind

noise, room noise or proximity effect.

Flat response. Provides the most natural sound in most applications.

Low-frequency cutoff. Provides a

15 dB-per-octave cutoff at 80 Hz. Helps

eliminate floor rumble and low-frequency

room noise from heating and air

conditioning systems. This setting may also

be used to compensate for proximity effect

or to reduce low frequencies that make an

instrument sound dull or muddy.

Low-Frequency Rolloff. Provides

a 6 dB-per-octave rolloff filter at 115 Hz. Use

this to compensate for proximity effect or to

reduce low frequencies that could make an

instrument sound dull or muddy.

FIGURE 2. LOW FREQUENCY RESPONSES

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 SPLs (ie.

close miked drums and guitar cabinets) from overloading the microphone. To activate

attenuation, move the switch to the “-15 dB” position.

0 dB - Use this switch for “quiet” to “normal” sound levels.

-15 dB - Use this switch position when in close proximity with extremely loud sound

sources such as kick drum, snare drum, or loud guitar cabinets.

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.

Integral Pop Filter

The KSM32 grille consists of 3 separate mesh layers that act as an integral pop filter which

helps reduce wind and breath noise. Depending on the performer, an external pop-protection

screen or windscreen (See Figure 3) may be necessary when close-miking vocalists.

Load Impedance

Shure recommends a load impedance of at least 1000 Ω. When used with modern

microphone preamplifiers (rated at 2500 Ω), the KSM32 provides higher maximum SPL

capability and output clipping level. When the attenuation switch is set to the -15 dB position,

the KSM32 can handle sound pressure levels of up to 160 dB and output +15 dBV into a load

of 5500 Ωor greater, with microphone attenuation.

SPECIFICATIONS

*20 Hz to 20 kHz; THD < 1%. THD of microphone preamplifier when applied input signal is equivalent to cartridge output at specified SPL.

**S/N ratio is difference between 94 dB SPL and equivalent SPL of self-noise, A-weighted.
