Brief Description This large-diaphragm condenser microphone has been designed on the basis of feedback from sound engineers who have used the C 12, C 12A, C 414 EB and C 414 B-ULS microphones in recording studios around the world for years. Using hand-selected state-of-the-art, reliable components as well as advanced manufacturing processes, the C 3000 meets the highest professional standards and will withstand severe handling in the recording studio for many years. The electronic circuitry of the microphone has been redesigned to achieve maximum dynamic range and a flat frequency response. Low self-noise and high headroom add up to a dynamic range of 136 dB (A-weighted). The transducer element uses advanced backplate technology and a diaphragm that is gold-sputtered on one side only to prevent local shorting to the back electrode even at extremely high sound pressure levels. The all-metal body ensures efficient rejection of RF interference so you can use the microphone near transmitter stations, along with wireless microphones or other communications equipment. Controls The C 3000 provides selector switches for the preattenuation pad and bass cut filter. Figure 1: Preattenuation selector 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 Figure 2: Bass cut 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.. 3 Powering The C 3000 provides low self-noise (just 13 dB(A)!) yet high headroom. The microphone requires a phantom power source providing 12 to 52 V as per IEC 61938. ATTENTION Risk of damage Do not connect the microphone to any power supply other than a phantom power so...
