FIGURE 1. KSM27 Front and Back Selecting Low-Frequency Response A three-position switch on the back of the KSM27 allows you to adjust the low-frequency response of the microphone, as shown in Figure 1. The low-frequency filter settings can be used to reduce wind noise, room noise or proximity effect.

(rated at about 2500 Ω), the KSM27 provides higher maximum SPL capability and out put clipping level. WIth the –15 dB pad engaged, the KSM27 can handle up to 153 dB SPL and output +15 dBV into a 2500 Ω or greater load.
Meets applicable tests and performance criteria found in European Professional Audio Products EMC Standard EN 55103 (1996); Part 1 (Emissions) and Part 2 (Immunity). The KSM27 is intended for use in environments E1 (residential) and E2 (Light Industrial) as defined in European standard EN 55103. EMC conformance is based on the use of shielded interconnecting cable.
