Get in Tune with Your Environment
Whether you mix, master, or work in live sound, having reliable information about your listening environment is crucial to delivering consistent, professional results. When setting up a new studio or working in a new venue, that’s precisely why Sweetwater engineers bring along a Beyerdynamic MM-1. This omnidirectional condenser measurement microphone has an incredibly thin tolerance: only +/- 1.5dB between 50Hz and 16kHz. When used in conjunction with a spectrum analyzer, the MM-1 can also give you accurate readings about your speakers’ SPL levels in addition to frequency response measurements. Finally, the MM-1 is diffuse field-calibrated with a linear frequency response at 90°, which makes it easy for novices and professionals alike to accurately measure their spaces.

The right tool for the job

The MM-1’s slender shape isn’t just for cosmetic appeal. Its narrow construction plus deep-set mic capsule was designed purposefully to mitigate the all-too-common SPL increases at high frequencies. This form factor gives you the most accurate, trustworthy information possible — plus, the free-field measurement data (at 0° and 90°) is actually available upon request by simply emailing Beyerdynamic.
