Dayton Audio’s OmniMic 40k is an essential tool for revealing the finest acoustic details. The robust device is engineered to deliver rapid and precise acoustic measurements essential for maximizing the performance of any audio system. Designed for professionals and hobbyists who demand perfection, the OmniMic 40k ensures that from initial acoustic measurement through to final system calibration, no detail goes unnoticed.

Featuring internal high voltage circuitry, the OmniMic 40k’s microphone offers an extremely wide dynamic range capable of capturing measurements up to 145 dB without suffering from compression or distortion. An easily accessible attenuator switch allows for level adjustments, ensuring outputs align seamlessly with the on-board ADC for maximum detail and precision. An exclusive addition is the IR receiver which, in conjunction with the PhotoLink, enables the system to precisely calculate both the time of flight and the distance between the acoustic source and the microphone. The sturdy stainless steel housing of the microphone further guarantees durability and sustained performance.

The innovative PhotoLink device sets the OmniMic 40k apart from competing measurement systems. Establishing an optical connection with the microphone, the PhotoLink enables exact calculation of delay and distance from the acoustic source to the mic capsule. This feature is crucial for accurate delay measurement and true phase capture, both essential for constructing precise on and off-axis simulations critical in designing any multi-way speaker system or array. The PhotoLink also features a visible 2.83V indicator to facilitate consistent signal level adjustment between measurements, essential for maintaining comparable sensitivity across different drivers. Remarkably, the PhotoLink operates passively, requiring no direct connection to the microphone or computer, thereby streamlining the setup process.

Easy to operate, the OmniMic 40k comes equipped with intuitive software that lets you start testing within minutes of unboxing. Every aspect of the sound from distortion up to 20,000 Hz to precise time of flight is easily accessible. Beyond functionality, its compact and portable design, coupled with an affordable price point, makes it an unrivaled choice in acoustic measurement.

Included are all the essentials: the OmniMic 40k microphone, PhotoLink, test leads, a 16.4 ft. USB cable, a compact microphone stand, a mic clip, and a wooden protective storage case, making it ready for immediate field use.

Trust in the Dayton Audio OmniMic 40k for a measurement experience that epitomizes accuracy, efficiency, and ease. Make it your go-to system to ensure your audio work resonates with clarity and depth, every time

Note:

For measurement up to 40,000 Hz, your system will need a digital-to-audio converter (DAC) with a sampling rate of 88.2kHz or higher and an amplifier capable of nearly flat response up to 40,000 Hz.
