Product Description

With DPA’s superior microphone capsule technology, the CORE 4088 Directional Headset bears the description “open, natural and reliable” incredibly well. The high quality of the microphone means that in acoustically demanding live performance environments, where background noise and feedback is a concern, the CORE 4088 will tackle these challenges with ease.

The CORE 4088 capsule is a pre-polarized first order pressure gradient transducer, hidden in a small and lightweight housing with dimensions just slightly larger than DPA’s well known miniature omnidirectional capsules.

The smooth and elegant design of the CORE 4088 makes it one of the most invisible headworn cardioid microphones on the market today. Sound quality, visual elegance and versatility go hand in hand to transform every show into the performance of a lifetime. Its mechanical design is based on the CORE 4066 headset microphone. The headset mount is exactly the same; the boom however is 3 centimeters longer in order to meet the need for placement at the corner of the mouth.

A wide range of connection adapters makes it possible to use the CORE 4088 with most of the professional wireless systems available and standard XLR connections.
