DPA CORE 4088 Directional Headset Mic
The DPA CORE 4088 Directional Headset Mic is the industry standard in professional headset mics. It offers an open and natural sound making it ideal for both spoken word and vocal performance applications.
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, this microphone will tackle these challenges with ease. The bass response is designed for optimal linearity at 2-3 cm (1 inch) 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 smooth and elegant design of the 4088 Directional Headset Microphone makes it the most invisible head-worn true cardioid microphone in the world. This microphone has a secure, dual-ear design that can be used for various performing talent applications. It has a small .64 cm (.25 in) diameter, which allows for discreet use. It only weighs 14 g (.5 oz) and is very comfortable when worn for long periods. The microphone can be mounted on the right or left side.
The boom is 3 cm (1 in) longer than on the omnidirectional version, which matches the need for placement at the corner of the mouth. To avoid “popping”, the capsule should not be placed directly in front of the mouth.
All CORE by DPA technology microphones are IP58 certified. This durability is achieved through a number of defense mechanisms:
• Water-repellant nano-coating of the cover and housing
• Hermetic sealing of the sensitive amplifier at the core of the mic
• Dual gold plating of the diaphragm
