AKG Acoustics C 2000 B - Manual

C 2000 B
Stage and Studio Condenser Microphone
Description
The C 2000 B is a versatile, side-address cardioid condenser
microphone intended for professional and home studio
applications as well as on-stage activities. It consists of a patent
pending one-half inch capsule element which is placed in a
larger baffle ring. This measure gives the C 2000 B more
forward directionality at high frequencies. The microphone’s
response is tailored to have a broad on-axis rise at high
frequencies, while maintaining a fairly uniform diffuse field over
the entire frequency band. The added presence at very high
frequencies is an asset in many micing situations, especially
home recording studios, while maintaining good feedback
rejection in live sound applications.
Its 0.5% THD point of 140 dB (150 dB with the integral 10-dB
pad engaged) and high sensitivity of 20 mV/Pa indicate that this
model can deliver maximum operating output signals in the
range of 4 volts. The self-noise floor is 20 dB (A), giving the
microphone an effective dynamic range of 120 dB. An integral
bass cut switch provides a gentle 6 dB per octave roll-off below
500 Hz, and as such will compensate for the proximity effect
(low frequency boost) associated with close micing.
The cardioid polar pattern, has been refined to give maximum
rejection across the frequency band at 180 degrees. Internal
shock mounting of the diaphragm assembly makes this model
studio friendly and easy to use in demanding live performances.
The SA41/1 stand adapter is included. Optional accessories
include the B18E battery supply unit and the H 100 external
elastic shock suspension.
