This premium side-address, cardioid condenser microphone features a large dual-diaphragm 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 exhibits an exceptionally smooth frequency response and ultra-wide dynamic range. The KSM42 is the premier choice for capturing sophisticated and intimate vocal performances.
The KSM42 is designed primarily for:
Secondary uses might include:
This microphone requires phantom power and performs best with a 48 Vdc supply (IEC-61938). However, it will operate with slightly decreased headroom and sensitivity with supplies as low as 1 1 Vdc.
Most modern mixers provide phantom power. You must use a balanced microphone cable: XLR-to-XLR or XLR-to-TRS.
Use the supplied ShureLockC] rubber suspension mount to secure the microphone to a floor or boom stand.
Thread the knurled locking ring securely to the base of the microphone. Do not overtighten.
The front of the microphone is marked by the Shure logo. Position this side toward the sound source.
An integrated three-stage mesh grille guards against wind and breath noise. IJse the included pop filter accessory for additional protection against breath and "plosive" noises. The pop filter magnetically attaches to the front of the shockmount ring.
To counter proximity effect, the KSM42 uses two diaphragms, one active and one passive, to create an acoustic phase shift at the rear of the microphone. This produces a broad "sweet spot" of uniform low-frequency response, allowing the performer to move closer or further from the microphone with minimal changes in sound quality.
