Stormembran kondensatormikrofon i SM-serien.
Når du trenger fullt frekvensområde for høyoppløst lyd.
Features
- 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
Specs
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
