Omnidirectional Microphone
unique natural & open soundThe DPA 4090 is a high-quality omnidirectional condenser microphone. Thanks to its unique natural and open sound, the 4090 is perfect for miking up instruments in the studio or on the stage. With 134 dB SPL handling, this microphone can be used with essentially any instrument including acoustic guitar, strings, piano and wind instruments.
As a result of their incredibly linear frequency response within the 20 Hz to 20 kHz range, sound system engineers can also use these mics for sound system alignment, testing and tuning. The sturdy and compact design features a 5.4 mm (.21 in) diameter pre-polarized condenser capsule in a tapered body measuring just 12 cm (4.76 in).

What Is Omnidirectional?
sensitivity at all anglesAn omnidirectional microphone has sensitivity at all angles, capable of picking up sound equally from all directions. This gives you an impressive natural and realistic sound compared to a cardioid mic. Omni mics are commonly used for picking up ambient sounds, along with miking a large sound source such as a choir in a recording situation.
>Although, due to their pickup pattern, omnis can also produce a lot of feedback in live situations. Nonetheless, it is recommended that you try a DPA omni first, because when used close to the sound source, the equal frequency response makes these mics a versatile addition to your audio collection. Often providing a more natural sound, it can handle extremely high sound pressure levels, without suffering from proximity effect and is not as sensitive to wind, pop or handling noise.
