The AKG D7WL 1 D7 Microphone Capsule attaches to the AKG WMS 4500 handheld wireless microphone transmitter, and delivers the patented varimotion sound quality found in the standard wired version. The D7 is a suitable choice for general speech and performance capturing on stage, lecterns, desktops and anywhere a high quality handheld microphone is needed. The dynamic microphone capsule doesn’t require any power and uses AKG’s patented varimotion technology. The supercardioid polar pattern is most effective at rejecting off-axis ambiance, feedback and noise.
