Shure KSM32 Instrucciones De Uso página 5

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 microphone. 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
side of the microphone toward the sound source. The rear of the microphone is
marked by the
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. See Figure 2.
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
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
Provides a 6 dB-per-octave rolloff filter at
115 Hz. Use this to compensate for
