Overview
Combining the legendary sound of the 4088 Directional Capsule with the lightweight and flexible d:fine Headset system, the d:fine 4288 Directional Headset Microphone is ideal for both spoken word and vocal performance applications. It offers accurate and natural voice intelligibility and very high-SPL capabilities - users can both speak and sing into the mic with no hint of distortion. This mic provides excellent off-axis rejection in high-SPL situations. It efficiently suppresses distant sound sources making it perfect for demanding live performance environments where background noise and feedback are concerns.
