High-output neodymium transducer; cardioid instrument microphone; designed specifically for bass instruments; extremely rugged; mounts on stands or instruments. The AKG D550 Dynamic Mic is a unidirectional dynamic microphone. It has been designed primarily for tough onstage use on bass instruments including kick drum, tuba, trombone, bass amps, etc. and uses a patented AKG Varimotion diaphragm. The wide frequency response of this microphone slightly emphasizes the mid and high frequencies to ensure a powerful sound. The D550 has a cardioid polar response. This means the microphone is most sensitive to sound arriving from in front of it, less sensitive to sound arriving from the sides, and hardly responds to sound from the rear. This pickup pattern is virtually the same for all frequencies (“frequency independent”). The strong plastic housing and the wire-mesh outer grille of the D550 protect the transducer system from damage. The outer grille and a layer of special fabric beneath it form a very effective windscreen to suppress pop and wind noise. An integrated stand adapter provides for precise microphone alignment with the instrument.


  • Response tailored for bass instrumental on-stage performance
