[. . . ] The resulting technical specifications are unique among today's microphones and will remain in the forefront of even tomorrow's microphones. The following main features are provided: · Two bass-cut positions with onset at 70 Hz and 150 Hz · to be powered from a 48 volts phantom powering source (acc. [. . . ] To DIN 45596) The following accessory is included: ­ with the C 480 B comb-ULS/61: · General Description: The design of this microphone is based on over thirty years of experience and gained know-how in condenser microphone development of our R & D engineers and at the same time considers new and future orientated technologies. The microphone meets therefore the highest technical standards and will withstand rough handling in studio applications. Special attention has been paid within this microphone to the complete linear transfer characteristics of all transmission parameters. The low inherent self-noise and the high overload point guarantees a dynamic range of this microphone of more than120 dB, which is substantially more than figures found in conventional microphones and other associated equipment. The switchable attenuation of the output level by 10 dB is especially useful in connection with high sound pressure levels (when used in close proximity to high-energy sound sources) and using input stages of amplifiers or mixing desks with limited input level capabilities. Otherwise, this associated equipment will overload before the maximum overload point of the microphone has been reached. Powering The C 480 B preamplifier may be powered in phantom technique according to DIN 45596. The two possible wiring methods are shown below: The following values for Rv (or 2 x Rv) are standardised: U= 48 V ± 4 V Rv 3300 Ohm 2 x Rv 6800 Ohm In case where single ended (grounded) amplifier inputs, or where no input transformers are available, either capacitors or optional transformers have to be wired into the audio lines to prevent any current leakage into the input circuitry.
