DPA 4090

Description

DPA d:screet 4090 omnidirectional microphone, hi-sens, P48 is a high-quality omnidirectional condenser microphone. Due to its uniquely natural and open sound, the 4090 is suitable for instrument-miking applications in the studio or on the stage.

With 134dB 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 20Hz to 20kHz range, sound system engineers can also use these mics for sound system alignment, testing and tuning.

The rugged and compact design features a 5.4mm diameter pre-polarized condenser capsule in a tapered body measuring just 12cm.
