AKG Acoustics C 3000 Controls, Filter, Preattenuation Selector, Microphone lets you increase

	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..
