CLEAR, ACCURATE & NATURAL SOUND
The 4288 Directional Flex Headset Microphone combines the legendary sound of the 4088 Directional Capsule with a lightweight and flexible headset system. It offers accurate, natural voice intelligibility and very high SPL capabilities. Users can both speak and sing into the mic with no hint of distortion.
The 4288 provides excellent off-axis rejection in high-SPL situations. It efficiently suppresses distant sound sources making it perfect for demanding live performance environments. 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 optimised for low distortion as well as humidity resistance.
Two boom lengths are available to accommodate different applications and head sizes: 100 mm (3.9 in) and 120 mm (4.7 in). The 120 mm (4.7 in) is the standard choice for most users. 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:
1. Water-repellant nano-coating of the cover and housing
2. Hermetic sealing of the sensitive amplifier at the core of the mic
3. Dual gold plating of the diaphragm
A BIT ABOUT CARDIOIDS
Named for its “heart shaped” polar pattern, a cardioid microphone has the most sensitivity at the front and less from the sides and the back. They come in many variations – with wider or narrower angles of sensitivity (supercardioid, hypercardioid, wide cardioid etc.). Although cardioids also pick up sound coming in from the sides, this off-axis sound will normally be more or less coloured and dampened. The unique DPA capsule technique, however, skips the colorisation of the sound coming from the sides or the rear of the mic and just reduces the sensitivity to these angles, and thereby, offers perfect sound stages. The amount of dampening depends on the exact specifications of the mic.
A cardioid microphone is, by definition, dampened -6 dB at the 90°side entry of the microphone but for many, the word cardioid generally covers mics with a directional pattern versus omnis, which pick up sound from all directions.
Due to their nature, directional mics are often used on the live stage – both during concerts as well as spoken-word events, to capture the focused sound of an instrument or voice. The narrow angle of sensitivity helps to minimise the bleed from other sounds on a busy stage. One thing to note with cardioid mics is the proximity effect. This causes an increase in bass response the closer the microphone is moved to the sound source. Therefore, check mic specs for the stated distance of measured flat frequency response when choosing a mic. In addition, cardioid mics are far more sensitive to wind, pop and handling noises, so be sure to take precautions to guard against this.
ADAPTER SYSTEM GIVES YOU FLEXIBILITY
The adapters for wireless systems give you flexible, simple and affordable possibilities. You are no longer bound to one wireless system. As circumstances change, you can just switch your adapter, instead of incurring the cost of a completely new microphone. When you make the switch, you won’t hear any loss or change in sound quality.
DPA’s miniature microphones work with all leading wireless mic solutions, such as Lectrosonics, Sennheiser, Shure, Sony, Wisycom, Zaxcom and many more. DPA Microphones’ ingenious adapter system is one of a kind in the industry. It protects your investment in fantastic sound for years to come.
