Description

Controls

The C 3000 provides selector switches for the preattenuation pad and bass cut

 

filter.

 

Preattenuation 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

 

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..
