filter. Controls
Preattenuation Selector

selector
The selector switch on the left-hand side of the
microphone (fig. 1) lets you increase the
microphone's headroom by 10 dB for distortion
free recordings of very loud sound sources or
close to sound sources. The preattenuation
pads prevent the microphone's output level,
particularly at low frequencies, from over-
loading the miniature transformers used in
mixer input stages, etc.
Bass Cut Selector
Figure 2: Bass cut
Rumbling or wind noise may cause distortion
at very low frequencies. The microphone's
switchable bass cut filter (refer to fig. 2) further
reduces low-end distortion. The filter slope is
more than 6 dB/octave at 500 Hz and below.
The bass cut also minimizes the proximity
effect that may arise when close-in miking
from less than 6 inches..
