Large dual-diaphragm side-address condenser vocal microphone.
The KSM42 is a premium side-address, cardioid condenser microphone featuring 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, which includes 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.
- 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" 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 shockmount 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
