The 4088 CORE Directional Headset Microphone for wireless with 3-pin LEMO connection (small) from DPA Microphones 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 roll-off will be relatively prominent at a greater distance due to the bass response design for optimal linearity at 1 in. from the sound source.
