Description
This condenser microphone has been designed on the basis of experience
AKG and its customers have gained worldwide over the last decades using
models such as the C 414 B. C 3000, and C 1000 S. The C 2000 B uses
advanced, reliable components to meet the highest professional demands
and withstand even long-time, tough handling in the studio and on stage.
The C 2000 B provides the following features:
The transducer capsule has been acoustically designed with a cardioid
polar pattern to make the microphone suitable for use both in the record-
ing studio and on stage.
The diaphragm is made of a plastic foil that is gold-sputtered on one side
to prevent local shorts to the back electrode even at extremely high
sound pressure levels.
A switchable preattenuation pad allows you to increase the maximum
SPL capability of your C 2000 B by 10 dB for distortion-free close-in
recordings. Many mixing console input stages use small transformers
that are susceptible to overload, particularly at low frequencies. The
C 2000B's pad prevents such overload.
A bass cut filter that is switchable on the microphone body reduces low-
end distortion due to uncontrolled rumble or wind noise even further.
Also, you can eliminate the proximity effect (occurring at working
distances of less than 4 inches) inherent in unidirectional microphones
by switching the bass cut filter in.
The filter has a 6 dB/octave slope starting at 500 Hz.
The all-metal die-cast body shields the microphone very effectively
against RF interference when using it near radio transmitters or
together with wireless microphones or other communication systems
and protects the microphone from the hardships of live use.
The built-in pop screen is ideal for vocal use.

An internal spider-type shock mount for the transducer effectively sup-
presses handling and cable noise.
A safety flange on the connector shaft prevents the microphone from
falling out of the spider suspension or stand adapter even when
mounted upside down.
With its high SPL capability, minimum distortion, and resistance to
extreme temperatures and high humidity, the C 2000B is a truly uni-
versal microphone.
Although the microphone capsule is shock mounted internally, you can use
the supplied H 100 "spider" suspension to reduce vibrational noise
from the stand or other sources even further. Remember to insert the
cable into one of the two grooves at the rear end of the outer ring for
strain relief. This removes mechanical pull from the connector and re-
duces vibrational noise that may be transmitted to the microphone by
the cable.
