• 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 systemsCombining the legendary sound of the 4088 Directional Capsule with the lightweight and DPA's flexible headset system, the 4188 Directional Headset Microphone is ideal for both spoken word and vocal performance applications. This mic 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 4188 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.Directional pattern - CardioidPrinciple of operation - Pressure gradientCartridge type - Pre-polarized condenserFrequency response - 20 Hz - 20 kHzSensitivity nominal, ±3 dB at 1 kHz - 6 mV/Pa; -44 dB re. 1 V/PaEquivalent noise level A-weighted - Typ. 26 dB(A) re. 20 µPa (max. 28 dB(A))Equivalent noise level ITU-R BS.468-4 - Typ. 38 dB (max. 40 dB)Distortion, THD < 0.5% - 137 dB SPL RMS, 140 dB SPL peakDistortion, THD < 1% - 139 dB SPL RMS, 142 dB SPL peakDynamic range - Typ. 116 dBMax.
