KSM42 Condenser Vocal Microphone


Product Code:
KSM42

This premium side-address, cardioid condenser microphone features a large dual-diaphragm capsule, optimized for world-class vocal recording and performance applications. With a tailored frequency response and extensive internal and external pop filtering, the single-pattern, dual-diaphragm design of the KSM42, featuring Prethos® Advanced Preamplifier Technology exhibits an exceptionally smooth proximity control and ultra-wide dynamic range. The KSM42 is the premier choice for capturing sophisticated, powerful and intimate vocal performances.

A milestone achievement in sound reinforcement, Prethos Advanced Preamplifier Technology employs transparent internal circuitry architectures that enable unprecedented audio quality and performance.


Features
  • Highly consistent cardioid polar pattern creates a broad “sweet spot” and natural off-axis response
  • Prethos® Advanced Preamplifier Technology exhibits extremely low self-noise with superior dynamic range, transient response and ultra-low distortion for transparent recording
  • Dual-diaphragm design with an active front, ultra thin (2.5 micron) 24-karat gold, low mass, 1-inch Mylar® diaphragm
  • Passive back diaphragm delivers exceptional control of low frequency proximity effect
  • Tailored low-frequency roll-off minimizes low frequency room noise
  • Integrated three-stage mesh grille guards against wind and breath noise
  • Open cage ShureLock® rubber suspension shock mount with low-profile Popper Stopper™ magnetic pop filter produces a natural space between performer and microphone
  • Extremely low self noise for critical studio vocal recording
  • Premium electronic components and gold-plated internal and external connectors
  • Durable zinc die-cast housing and hardened low carbon steel grille
  • Internal shock mount to reduce unwanted handling and stand noise
Specifications
  • Cartridge Type: Dual-Diaphragm, Front-Active, Externally Biased Condenser
  • Frequency Response: 60 to 20,000Hz
  • Polar Pattern: Cardioid
  • Output Impedance: 147 Ω
  • Sensitivity (at 1 kHz, open circuit voltage):
    −37 dBV/Pa (14.1 mV)
    1 Pascal=94 dB SPL
  • Maximum SPL (1 kHz at 1% THD):
    1000 Ω load: 139 dB
    2500 Ω load: 139 dB
    THD of microphone preamplifier when applied input signal is equiva¬lent to cartridge output at specified SPL
  • Signal-to-Noise Ratio (referenced at 94 dB SPL at 1 kHz):
    86 dB
    S/N ratio is difference between 94 dB SPL and equivalent SPL of self noise, A-weighted
  • Dynamic Range (at 1 kHz):
    1000 Ω load: 131 dB
    2500 Ω load: 131 dB
  • Common Mode Rejection (10 Hz to 100 kHz): > 60 dB
  • Clipping Level (20Hz-20 kHz at 1% THD)
    1000 Ω load: 6.5 dBV
    2500 Ω load: 8 dBV
  • Self Noise (typical, equivalent SPL, A-weighted): 8.5 dB
  • Polarity: Positive pressure on diaphragm produces positive voltage on pin 2 with respect to pin 3
  • Weight:
    Net: 494 g
    with shock mount and pop filter: 820 g
  • Connector: Three-pin professional audio (XLR), male
  • Power Requirements: 11 to 52 Vdc phantom, 6 mA
