Operation
Power Requirements
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 11 Vdc.
Most modern mixers provide phantom power. You must use abalancedmicrophone 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 knurled locking ring securely to the base of the microphone. Do not overtighten.
Positioning the Microphone
The front of the microphone is marked by the Shure logo. Position this side toward the sound source.
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-frequency response, allowing the performer to move closer or further from the microphone with minimal changes in sound quality.
Three-pin professional audio (XLR), male, balanced
Polarity
Positive pressure on diaphragm produces positive voltage on pin 2 with respect to pin 3
Power Requirements
11–52 V DC[4] phantom power (IEC-61938), 6 mA
Net Weight
494 gwith shock mount and pop filter: 820 g
[1] 1 Pa=94 dB SPL
[2]THD of microphone preamplifier when applied input signal level is equivalent to cartridge output at specified SPL
[3]S/N ratio is the difference between 94 dB SPL and equivalent SPL of self noise, A-weighted
[4]All specifications measured with a 48 Vdc phantom power supply. The microphone operates at lower voltages, but with slightly decreased headroom and sensitivity.
