The O40: Precision Meets Performance
The O40 is a world-class omnidirectional microphone designed for the utmost accuracy in measurement and instrument applications. Crafted from solid 304 stainless steel and equipped with the fastest Capsule & Amplifier combination in the market, the O40 boasts an ultra-wide frequency response from 4 Hz up to 40 KHz while maintaining a very tight tolerance of ±0.5 dB.
With its low SDC noise level of 19 dBA and a distortion-free maximum SPL of 137 dB, the O40 can handle any sound source, ensuring results that are accurate, free of distortion, and uncolored. Certified by NTI as a Class 1 Microphone, the O40 excels in applications requiring high precision, such as speaker measurement, venue and room calibrations, cabin and engine noise measurements, and matched array applications. The O40 is also impeccable as a studio instrument recording microphone, capturing the natural sound of strings, percussion, woodwinds, and other instruments with the utmost fidelity. For outdoor use, the supplied hydrophobic acoustic foam piece ensures optimal performance in various environments.
