Shure KSM42 Dual-Diaphragm Condenser Microphone Overview
The Shure KSM42 is a large professional dual diaphragm microphone. A side address, cardioid condenser microphone, it is optimised for unparalleled vocal recording and performance applications.
The KSM42 features a tailored frequency response and meticulous internal and external pop filtering. The dual-diaphragm design enables smooth proximity control and broad dynamic range, perfect for recording vocals.
- Highly consistent cardioid polar pattern creates a broad "sweet spot" and natural off-axis response
- 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
- Prethos™ Advanced Preamplifier Technology exhibits extremely low self-noise with superior dynamic range, transient response and ultra-low distortion for transparent 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
