The AKG 3138X00090 D5 Microphone with on off switch for lead and backing vocals delivers a powerful sound even on the noisiest stage. Its supercardiod polar pattern ensures maximum gain before feedback. The D5 stands for a crisp sound that cuts through every mix. For the D5, AKG employed the first microphone diaphragm ever whose thickness varies across its diameter. The new Laminated Varimotion diaphragm deep-drawing process allows the diaphragm itself to be fine-tuned with no extra tuning resonators, leading to a quantum leap in audio performance. The D 5's dual shockmount eliminates any kind of mechanical noise for trouble-free live use.
