Crown PZM20RW

Crown PZM20RW Crown PZM20RW Description: Crown PZM20RW Pressure Zone Professional Microphone For Conference Table Use White Version PZM Series PZM (Pressure Zone Microphone) Series are omnidirectional boundary microphones. They can be placed on a large surface such as a table, floor, wall, or lectern. PZMs prevent phase interference from surface reflections, allowing a wide, smooth response. Microphone sensitivity is boosted 6 dB by the surface mounting. Crown PZM Series microphones offer serious tools for the sound reinforcement and recording professional, along with cost-effective solutions for a variety of other needs. As the first licensed manufacturer of the Pressure Recording Process (the foundation of PZM technology), Crown has developed the most successful line of PZM microphones available today. Crown PZM20RW Specifications: Type: Pressure Zone Microphone. Element: Electret condenser. Frequency response (typical): 80 Hz to 20 kHz (see Fig. 1). Polar pattern: Hemispherical on an infi nite plane. Open circuit sensitivity: 7 mV/Pa* (43 dB re 1 volt/Pa). Power sensitivity: 43 dB re 1 mW/Pa. EIA sensitivity 135 dBm. Impedance: 240 ohms balanced. Recommended minimum load impedance 1000 ohms. Equivalent noise level: 20 dB SPL (0 dB = 0.0002 dyne/cm2), A-weighted. S/N ratio: 74 dB at 94 dB SPL. Maximum SPL: 150 dB SPL at the microphone produces 3% THD. Polarity: Positive pressure on the diaphragm produces positive voltage on terminal 2 with respect to terminal 3 of the output terminal strip. Operating voltage: Phantom power, 12 to 48 volts DC, positive voltage on terminals 2 and 3 with respect to terminal 1 of the output terminal strip. Current drain: 1.1 mA. Color: Black. Connector: Screw terminals. #1 shield, #2 audio inpolarity, #3 audio return. Cable: None supplied; use 2-conductor shielded microphone cable. Weight: 8.1 ounces (230 grams). Dimensions: See Figs. 2A and 2B. Optional accessories: Crown PH-1A phantom power supply (single channel, battery or AC adapter powered). *1 pascal = 10 dynes/cm2 = 10 microbars = 94 dB SPL.
