OPERATION Power Requirements This microphone requires phantom power and performs best with a 48 Vdc supply (IEC-268-15/DIN 45 596). However, it will operate with slightly decreased headroom and sensitivity with supplies as low as 11 Vdc. Most modern mixers provide phantom power. You must use a balanced microphone cable: XLR-to-XLR or XLR-to-TRS. Suspension Mount ® Use the supplied ShureLock rubber suspension mount to secure the microphone to a floor or boom stand. Important: Thread the knu

Pop Filter An integrated three-stage mesh grille guards against wind and breath noise. Use 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. Reduction of Proximity Effect 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- f
