beyerdynamic MM 1 Condenser Measurement Microphone (Omnidirectional)

The
Beyerdynamic MM 1 measurement microphone can be used anywhere that requires
precise results. Featuring an omnidirectional polar pattern, this microphone is
ideal for measuring studio spaces, PA systems and sound reinforcement systems.
When used in combination with a spectrum analyzer, it can monitor not only
frequency response measurements but also the sound pressure level of speakers.
The MM 1 also provides a valuable service when it comes to measuring audio
signals for research, development, and industry.

Strictly Accurate

The MM 1 boasts impressively high measurement precision, both live and in the
studio. Beyerdynamic manufactures these microphones within an extremely narrow
tolerance with a deviation of plus/minus 1.5 dB between 50 Hz and 16 kHz. This
is made possible by our specialists checking the frequency response of each
individual microphone by hand.

Its Whats Inside That Counts

A high-quality back-electret condenser capsule serves as a pressure receiver in
the MM 1. The microphone is diffuse field calibrated and demonstrates a linear
frequency response at 90 degree. This makes it easy to measure studio spaces,
for example, without the need for too much preparation.

An Unconventional Alternative

The MM 1 is anything but a one-trick pony. It delivers good results as an
unconventional alternative for instrument recordings, perfect for spontaneously
recording song ideas.

Quality Made In Germany

Handmade at the company headquarters, the MM 1 stands for beyerdynamics high
manufacturing quality. Measurement-relevant components such as the mounting
board are manufactured in-house and individually calibrated.

Form Follows Function

The MM 1s shape was designed to deliver exact measurement results. Thanks to
the narrow solid metal housing with a recessed microphone capsule, the
construction has very little impact on the sound field. This means that an
increase in sound pressure at high frequencies can be largely avoided. The
lightweight, compact microphone is also easy to position. This classic
microphone now comes safely stored in a sturdy hard case.

Individual Calibration Data

As with all microphones in the M series, the MM 1 is measured at the end of the
production process. In addition, upon request, Beyerdynamic will provide the individual
calibration data for 0-degree and 90-degree free-field measurements via email.

Durable Materials

The microphones are designed for daily use in professional conditions, which is
why only durable materials are used in their construction. If the microphone
nevertheless gets damaged, the service policy means that almost every part can
be replaced.
