DPA’s 4090 microphone represents the pinnacle of sound capture. With its omnidirectional pickup pattern, it records uniformly from all directions, ensuring authentic sound reproduction. Suitable for high sound pressure levels up to 134 dB SPL, it excels at miking a variety of instruments, including percussion, strings and wind instruments. Its compact design incorporates a 5.4 mm diameter pre-polarized condenser capsule, housed in a slim body measuring just 12 cm.

The 4090 features a linear frequency response of 20 Hz to 20 kHz, making it indispensable for aligning, testing and adjusting audio systems. Its robust design and high sensitivity make it a preferred choice for professional sound engineers. Unlike cardioid microphones, the 4090 captures a balanced sound spectrum across its entire surface, avoiding proximity effect.
