The SENNHEISER's MKE 40EW is a condenser lavalier wireless microphone that works with the Evolution Wireless Series bodypack transmitters SK 100, SK 300, and SK 500. It is highly suited to capture speech on stage or in other live sound applications, with a cardioid polar pattern that helps avoid unwanted sound from entering through the mic and a high gain-before-feedback. The MKE 40 has a frequency response of 40 Hz to 20 kHz and can handle sound pressure levels of up to 118 dB. It can be utilised to capture a direct sound with precise bass reproduction by close-miking both speech and instruments. Two windshields (black and grey), a clip (black), and the MZM 2 / MZM 10 magnetic mount set are included with the microphone.
