Shure SM27 Kraków

Mikrofon studyjny Opis i dae Techniczne, ze strony producenta: The SM27 is a rugged and versatile large-diaphragm, side-address cardioid condenser microphone. It has low self-noise and extended frequency response that picks up vocal and instrument nuances with clarity. Uniform cardioid pattern for superior off axis rejection Superior transient response from a low-mass large Mylar® diaphragm Flat, neutral frequency response for natural reproduction on stage or in the studio 3-position switchable low-frequency filter helps reduce unwanted background noise or counteract proximity effect for consistent, extended low-end Durable metal construction. Three separate mesh layers reduces wind and breath noise. 15dB pad for performance consistency across a wider range of high SPL sources. Type Condenser (externally biased) Frequency Response 20 to 20,000 Hz Polar Pattern Cardioid Impedance 150 Ohms (140 Ohms actual) Sensitivity(at 1 kHz, open circuit voltage) -37 dBV/Pa 1 Pascal=94 dB SPL Maximum SPL (1 kHz at 1% THD) 1000 Ohm load: 133 dB (147 dB, Pad on) 2500 Ohm load: 138 dB (152 dB, Pad on) Signal-to-Noise Ratio (referenced at 94 dB SPL at 1 kHz) 84.5 dB S/N ratio is difference between 94 dB SPL and equivalent SPL of self noise, A-weighted Dynamic Range (at 1 kHz) 1000 Ohm load: 123 dB 2500 Ohm load: 128 dB Common Mode Rejection (20 Hz to 20 kHz) > 50 dB Clipping Level (20Hz-20 kHz at 1% THD) 1000 Ohm load: 1 dBV 2500 Ohm load: 7 dBV THD of microphone preamplifier when applied input signal is equivalent to cartridge output at specified SPL Self Noise (typical, equivalent SPL, A-weighted) 9.5 dB Polarity Positive pressure on diaphragm produces positive voltage on pin 2 with respect to pin 3 Weight Net: 642 g (22.6 oz.) Switch Attenuator: -15 dB Low Frequency Response: flat; -6 dB/octave below 115 Hz; -18 dB/octave below 80 Hz Connector Three-pin professional audio (XLR), male Power Requirements 48 Vdc phantom, 5.4 mA
