on the recording console; the result is lower noise. The flat position provides a smooth, flat, high frequency response for natural sound reproduction. The PZM 6D has a small plate. Its low profile, unobtrusive appearance is appreciated in conference rooms, as well as on television, film and video productions. When suspended over an orchestra on a clear panel, the PZM 6D practially disappears. Its miniature, permanently attached 15 foot cable also reduces visual clutter. The output is a male 3 pin XLR type, balanced and low impedance, which permits long cable runs without hum pickup or high frequency loss. Like other Pressure Zone Microphones, the PZM 6D utilizes the Pressure Recording Process in which a miniature condenser microphone capsule is positioned very close to a sound reflecting plate or boundary. The capsule is mounted in the Pressure Zone just above the boundary, a region where sound coming directly from the sound source combines in phase with sound reflected off the boundary. The benefits are excellent clarity and reach, a hemispherical polar pattern, uncolored off axis response, and a wide smooth frequency response free of phase interference. SPECIFICATIONS Type Pressure Zone Microphone. Transducer Electret condenser. Frequency response 20 Hz to 20 kHz. See Fig. 1. Polar pattern Hemispherical when used on a floor, wall or ceiling. Open circuit sensitivity 7 mVPa 43 dB re 1 volt Pa. Power sensitivity 43 dB re 1 mWPa. EIA sens
