DPA Microphones' 4088 CORE Directional Headset Microphone with TA4F Connector for Shure Wireless provides excellent off-axis rejection in high-SPL situations and efficiently suppresses distant sound sources making it ideal for demanding live performance environments where background noise and feedback are concerns. The bass response is designed for optimal linearity at 1 in. from the sound source, meaning that the bass roll-off will be relatively prominent at a greater distance.
