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.
