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.
