Overview
Legendary sound - flexible earset
Combining the legendary sound of the 4088 Directional Capsule with the lightweight and DPA's flexible headset system, the 4288 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.
- Headset (two ears) - Comfy and most secure option.
- Pristine audio quality
- Lightweight and flexible
- Easy mounting to the left or right
- Minimal visual impact
- Resistant to humidity
- Flexible adapter system fits most professional wireless systems
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, 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.
The 4288 is available as an earset or headset. Earset variants are the quickest to put on and often the best choice when miking needs to be fast and easy for example for conference use. Headset variants sit more securely around the head and are ideal for active performance situations. Both types are ergonomically designed to fit comfortably and easily. This mic adjusts to fit any ear size and head shape while at the same time it mounts securely and is hardly visible. By rotating the boom and the earhook, the microphone can be easily used on either the left or the right ear. The connector splits the cable from the microphone boom allowing you to swap broken cables and / or wireless connectors quickly.
IP58 certified
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
