RE420 (cardioid) and RE520 (supercardioid) are specifically engineered to deliver best-in-class performance at a best-in-class price point, benchmarked across critical technical categories including dynamic range, maximum SPL, self-noise and transient response all with the pure, accurate audio quality for which the RE series is renowned.The RE520s supercardioid pattern ensures superior sonic isolation and high gain-before-feedback, to maintain a vivid vocal presence even in the most challenging stage environments. It provides tight lowfrequency response, natural-sounding mids and detailed highs.Main Features:Premium condenser element delivers a highlydetailed, full, and vivid soundSupercardioid polar pattern provides excellent acoustic isolation and feedback controlMulti-stage pop filter minimizes breath blasts and plosivesSelectable high-pass filter reduces undesirable low frequency content when engagedVibration-absorbing internal shock mount minimizes handling noiseSpecifications:Element type: Self-biased condenserFrequency response:40 Hz-20 kHzPolar pattern: SupercardioidSensitivity, open circuitvoltage @ 1 kHz: 5.6 mV/Pascal (-45 dBV/Pa)Clipping (max SPL): 150 dB SPL (1% THD)Self noise: 17 dB SPL “A” weighed (0 dB=20 Pa)Dynamic range: 133 dBSignal-to-Noise ratio: 77 dBOutput impedance: 200 ohmsPower requirements: 48 VDC phantom powerPolarity: Positive pressure on diaphragm produces positive voltage on pin 2 relative to pin 3Electrical contact: 3-pin, XLR-typeFinish: Black polyurethane paintMaterials: Zinc die cast, steel wire cloth grilleDimensions, length: 7.6 in.
