Combining the legendary sound of the 4088 Directional Capsule with the lightweight single earset system, the 4288 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 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 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.
Two directional boom lengths are available to accommodate different applications and head sizes: 120 mm (4.7 in) and 100 mm (3.9 in). The boom on this directional mic 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. The 120 mm (4.7 in) is the standard boom length that fits most people.
*Physical Microphone boom length comes in 100mm or 120mm. Distance from Ear-hook to sound source/mouth can be further adjusted +/- 15mm via the ear-hook slider.
*This microphone is convertible to a single-ear wearing style. Watch Video Here.
*All DPA Microphones are condenser Microphones and require Phantom Power.
THIS IS THE CORE+ VERSION OF THIS PARTICULAR DPA MICROPHONE
CORE+ is a revolutionary leap ahead in microphone design, blurring the lines between what is and isn’t acoustically possible. This technology neutralizes distortion across the entire dynamic range of the microphone making any residual distortion imperceptible to the naked ear and virtually unmeasurable.
- Effectively negates microphone distortion across the entire dynamic range
- Captures the purest, clearest sound at the source
- Lets sound engineers focus on shaping an extraordinary experience for the audience
- Reduces hassle from unpredictable challenges in the live show environment
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
