• Cardioid instrument microphone
• Designed specifically for bass instruments
• High performance Varimotion diaphragm (AKG patent)
• Extremely rugged
• Mounts on stands or instruments
The D 550 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 micro-
phone slightly emphasizes the mid and high frequencies to
ensure a powerful sound. The D 550 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 D 550 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.
