The Shure Model SM85 is a professional-quality, hand-held, unidirectional condenser microphone designed for the most demanding applications in sound reinforcement, broadcasting and studio recording. It is especially suitable for applications requiring wide fre- quency response, low distortion characteristics, very low RF susceptibility, and reliable operation over a wide range of temperature and humidity extremes. The SM85 makes optimum use of proximity effect to give the per- former control of low-frequency sound, from the warm intimacy of close miking to the natural sounds of normal-to-distant miking. The SM85 also features an in- tegral wind and pop filter, a high-frequency presence peak, a controlled low-frequency rolloff, and an effec- tive shock mount for reduced stand and handling noise. The case is constructed of aluminum for light weight and ruggedness, with a steel grille and durable black finish./The SM85 IS designed for simplex (phantom) power- ing from an external supply or directly from sound rein- forcement, broadcast, or recording equipment. The SM85 operates over an extremely wide voltage range of 11 to 52 Vdc, covering both DIN Standard 45 596 simplex of 12 and 48 volts, and the proposed 24-volt /The microphone is supplied with an accessory swivel adapter. Model SM85-LC is supplied without a cable, and Model SM85-CN is supplied with a 7.6m (25 ft) TRIPLE-FLEX@ microphone cable with professional audio connectors. Two dual-channel power supplies ;+lo (Models PSI and PSlE2) are available for providing simplex power to the SM85
