The best of both worlds. The AKG D7 Switched Microphone provides all the reliability of a dynamic mic with the open tone of a condenser capsule. The result is clean studio quality sound for live stage performances. Crisp sound. Clean components. The D7 capsule is kept spotless to ensure zero interference with the audio. A precision dust filter keeps out sound-changing pollution whilst the hum compensating coil prevents unwanted buzzing from getting in your way. When youre performing you dont want to be worrying about noise from handling the mic. Thats why the D7 reduces handling noise with a mechanically suspended capsule. Off-axis sound is rejected with the supercardioid polar pattern so you know your microphone is focussing on whats important - you.
