Additional Information

Customer Review Summary

The DPA 4090 is a top-tier microphone from DPA, yet it already offers a professional quality that bodes well for future releases in their microphone range.

This compact mic is easily portable and can be discreetly placed on stage or in a TV studio. Its sound reproduction is precise and detailed, surprisingly capturing low frequencies well for a small diaphragm microphone.

While some users may prefer a more coloured sound, the DPA 4090 maintains a neutral character, making it particularly suitable for classical music. Its omnidirectional pattern excels with acoustic instruments, from folk guitars to orchestras. When paired with a second identical microphone, it forms an excellent AB setup capable of capturing everything in a theatre, exhibiting great dynamic range and handling high sound pressure levels with ease.

The microphone operates silently and should be used with a preamp that preserves signal integrity. It comes packaged in a lightweight plastic case, which includes a foam pop filter and a basic microphone mount.

In terms of sound quality, the DPA 4090 delivers impressive clarity, presenting guitars in a beautifully realistic manner. Bass frequencies are warm and clear rather than muddy, while the midrange may be slightly critical on classical guitars—but not harsh. Overall, the microphone’s ability to capture a wide frequency spectrum positively influences recording quality, especially when positioned thoughtfully. Many would consider it a fantastic choice for its price point, even favouring it over other well-regarded models.

Despite its strengths, some may find it less suitable for live settings, as transitioning from a lavalier to this type of microphone can be challenging. However, it performs well in studio environments, allowing for effective room equalisation and omnidirectional captures without sounding lifeless. The DPA 4090 proves to be an excellent choice, particularly for guitar recordings, and serves as a perfect complement to other high-end microphones.
