Description

The Earthworks M30 Omni Measurement Microphone is New Delivered to all areas of the UK using our roadie delivery service.

The M30 is not just any old mic; it's an omni measurement mic. It offers a serious level of accuracy in both frequency response and the time domain. It manages to remain stable even during changes in atmosphere and temperature conditions. Add in an extremely quick impulse performance (granting precise wide-band response) and low handling noise, and you've got yourself an excellent piece of engineering. 

Unrivalled Utilities 

A flat frequency response ensures that the omnidirectional polar pattern can remain incredibly consistent. An 140dB SPL rating ensures it can operate without any distortion too. A linear phase response and speedy impulse response make the mic work well with audio system measurement applications like SIM, SMART, REW etc. You can even use it for loudspeaker design and the aligning of your PA system.  

Meticulous Design & Build Process 

Before finding its way to you, every M30 is tested and tuned by hand; it will also come with a dedicated frequency response chart that's unique to the microphone. 

Features
