Shure KSM32 Instrucciones De Uso página 6

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 Ω or greater, with microphone attenuation.
