This size helps shape response with the warmth and transparency that are typical of other high-quality AKG models. Its design provides a very low self noise floor of 14-dB-A, along with a maximum level capability of 140 dB, producing an overall operating range in the studio of 126 dB. Through the 10dB pre-attenuation switch the operating range of the microphone may be shifted up to 150 dB for close-in pickup of very loud sound sources. A bass cut switch provides a gentle 6-dB per octave roll-off below 500 Hz, compensating for proximity effect in vocal recording. The capsule assembly is internally shock mounted for low handling noise, and an internal foam sheath minimizes breath noises and pops with minimal attenuation of high frequencies. Tailored for the modern studio, the C 3000 B has the typical AKG large diaphragm “signature contour,” a slight dip at 2.5 kHz followed by a rise at 5 - 6 kHz and 9 - 11 kHz. Its cardioid pickup pattern is extremely well controlled, providing excellent off-axis rejection across the entire frequency band. The H 100 elastic suspension mounting is an included accessory with the C 3000 B. Optional accessories include the B 18 battery power supply, and the W 414 wind screen, The microphone is transformerless and accepts phantom powering over the range from 9 volts to 52 volts dc. The C 3000 B is equally at home on-stage as it is in the studio. Specifications Transducer type: 1 in.
