Dynamic microphone for miking instruments and backing vocals in tough night-after-night onstage use. The D 770 features a cardioid polar pattern that is virtually the same for all frequencies ('frequency independent') and uses a patented AKG Varimotion diaphragm.

The D 770 is fitted with a shock absorbing steel wire-mesh inner grill and a wire-mesh outer grill for transducer protection against damage.
