Combining the legendary sound of the 4088 Directional Capsule with the lightweight and flexible d:fine Headset system, the d:fine 4188 Directional Headset Microphone 4188 DL F B00 LE (4188-DL-F-B00-LE, 4188/DL/F/B00/LE, 4188_DL_F_B00_LE) 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. In high-SPL events, or when feedback is a concern, the 4088 Directional Capsule will tackle these challenges with ease. The bass response is designed for optimal linearity at 2-3 cm (1 in) from the sound source. This means that the bass roll-off will be relatively prominent at a greater distance - a paramount factor when it comes to rejection of background noise and in the fight to avoid feedback. The microphone capsule is also optimized for low distortion as well as humidity resistance.
