DPA 4090 Omnidirectional Condenser Microphone

The DPA 4090 is a high-quality omnidirectional condenser microphone. Due to its uniquely natural and open sound, the d:dicate 4090 is suitable for instrument-miking applications in the studio or on the stage.

d:dicate 4090 Omnidirectional Microphone, Normal SPL, P48

With 134 dB SPL handling, this microphone can be used with essentially any instrument from acoustic guitar and strings to piano and wind instruments. Due to their remarkably linear frequency response in the 20 Hz to 20 kHz range, sound system engineers can also use these mics for sound system alignment, testing and tuning.

The rugged 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).

d:dicate 4091 Omnidirectional Microphone, Loud SPL, P48

With 144 dB SPL handling, this microphone can meet just about any challenge including miking an electric guitar amp.

It is also an excellent microphone for use with percussion instruments as well as wind and string instruments. Due to their remarkably linear frequency response in the 20 Hz to 20 kHz range, sound system engineers can also use these mics for sound system alignment, testing and tuning.

A bit about omnis

An omnidirectional microphone has sensitivity at all angles – in principle picking up sound equally from all directions. This gives you extremely natural and realistic sound compared to a cardioid mic. Omni mics are often used for picking up ambient sounds, as well as miking a large sound source such as a choir in a recording situation. Unfortunately, due to their pickup pattern, omnis can also produce a lot of feedback in live situations.

Nonetheless, we recommend that you try a DPA omni first because, when used close to the sound source, the equal frequency response makes these mics a flexible addition in your audio toolbox. It will often give a more natural sound, it can handle extremely high sound pressure levels, it does not suffer from proximity effect and is not as sensitive to wind, pop or handling noise.
