DPA 4288-DC-F-F10-ME 4288 Directional Flex Earset Mic with 100 mm Boom in Beige with TA4F Mini-XLR

This item from DPA's deep roster is the 4288-DC-F-F10-ME, a 4288 series Directional Flex Earset Mic with a 100 mm Boom that comes in the color Beige with a TA4F Mini-XLR connector. Combining the legendary sound of the 4088 Directional Capsule with the lightweight and DPA's flexible headset system, the 4288-DC-F-F10-ME 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 great 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.
