This D7 dynamic microphone head from AKG has the subtle and open sound of a condenser capsule, combined with the powerful resonance of a dynamic microphone. The specially developed double diaphragms can vibrate unhindered, resulting in a particularly sparkling and clear sound. The use of laminated material dampens peaks in the frequency range. This, along with the supercardioid pattern, allows the D7 to generate a lot of power output without whistling around. The D7 head has a built-in steel dust filter that protects the diaphragm, giving you many years of trouble-free microphone happiness. This microphone head is intended for use with AKG's HT4500 handheld transmitter.
