A low-profile microphone featuring a cylindrical design for ceiling, wall or tabletop installations. Intelligibility is excellent, with low frequencies below the voice range rolled off to reduce the pickup of HVAC rumble. XLR connector, phantom powered. Specifications Transducer type: Electret condenser. Frequency response (typical): PZM-10: 80 Hz to 20,000 Hz. See Fig. 1. PZM-10LL: 100 Hz to 20,000 Hz. See Fig. 2. Polar pattern: Hemispherical. Impedance: PZM-10: 240 ohms, balanced. PZM-10LL: 75 ohms, balanced. Recommended minimum load impedance 1000 ohms. Open circuit sensitivity: PZM-10: 2.5 mV/Pa* (–52 dBV/Pa). PZM-10LL: 1.4V/Pa* (+3 dBV/Pa). See Table 1. Power sensitivity: PZM-10: –52 dBm/Pa*. PZM-10LL: +8 dBm/Pa*. Equivalent noise level (self-noise): 26 dB SPL typical (0 dB = .0002 dyne/cm2), A-weighted. S/N Ratio: 68 dB at 94 dB SPL. Maximum SPL: 120 dB SPL produces 3% THD. Operating voltage: PZM-10: 12 to 48V phantom power, positive voltage on pins 2 and 3 with respect to pin 1. PZM-10LL: 12 to 24V DC, positive voltage on red lead with respect to shield. Polarity: PZM-10: Positive pressure on the diaphragm produces a positive voltage on pin 2 with respect to pin 3 of output connector. PZM-10LL: Positive pressure on the diaphragm produces a positive voltage on white lead with respect to black lead. PZM-10 ® PZM-10LL POLAR PATTERN Current drain: PZM-10: 400 microamperes. PZM-10LL: 2.8 mA at 12V DC, 4.22 mA at 24V DC. See Table 1. Output connectors: PZM-10: Male XLR type (3-pin pro audio). PZM-10LL: None. Cable: PZM-10: None supplied. Use 2-conductor shielded mic cable. PZM-10LL: 12-in., permanently attached 3- conductor shielded cable. Red: B+, White: audio+, Black: audio–, Shield: ground. Materials: Steel plate and housing. Finish: Off-white. May be painted any color; take care to first seal the opening between the capsule and boundary plate. Model PZM-10BLK has a black finish, and can be custom ordered from your Crown dealer. Net weight: PZM-10: 2.6 oz. (73.6 g). PZM-10LL: 3.3 oz. (93.9 g).
