The Perception 120 USB has attenuation and bass-cut selector switches.
Attenuation selector switch
Selector switch 1 on the right-hand side
of the microphone enables you to
increase the control limit by 20 dB to
enable distortion-free recording of very
loud sound sources and in close
proximity to sound sources. The
preattenuation pads
microphone's output level, particularly at
low frequencies, from over-loading.
Bass-cut selector switch
Rumble or wind noises, etc. may cause
distortion at the lowest frequencies. The
switchable bass-cut provides additional
distortion reduction. The filter slope is 6
dB/octave with a corner frequency of
120 Hz. The bass-cut also counteracts
the proximity effect that can occur when
the microphone is only a short distance
(less than 15 cm) from the sound
source.
