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.

Beyerdynamic: quality you can count on

Beyerdynamic microphones are held in high esteem at Sweetwater due to the company's unwavering commitment to excellence since its founding in 1924. The MM-1 — like all Beyerdynamic products — is designed and crafted in Germany to the most stringent engineering standards, using only the highest-quality materials. Experience the Beyerdynamic difference: add an MM-1 to your mic locker today!

Beyerdynamic MM-1 Omnidirectional Condenser Measurement Microphone Features:

  • Omnidirectional electret condenser measurement microphone for measuring frequency response in studios and venues
  • Can be used with a spectrum analyzer to measure SPL from speakers as well
  • Also useful for R&D and various other industrial applications
  • Extremely narrow tolerance of only +/- 1.5dB between 50Hz and 16kHz
  • Narrow shape plus deep-set mic largely avoids SPL increases at higher frequencies
  • 0° and 90° free-field calibration data available upon request by emailing Beyerdynamic
  • Easy for both novices and professionals to use effectively
  • Handmade in Heilbronn, Germany

What is Demo Gear?

At Sweetwater, we're so picky that what we call a "demo" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

What demo means to us is that we've had it out of the box, or maybe it was in a customer's hands for a few days and isn't "factory fresh" as a result. Every demo item we sell has Sweetwater's 2-year Total Confidence Coverage™ warranty, and has been tested and verified up to "new" specs by our factory-authorized technicians to make sure it's in perfect working order before we ship it to you.

When you buy a Demo item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!
