FREQUENCY RESPONSE & POLAR PATTERN
The displayed frequency response curve and polar pattern correspond to a typical production sample for this micro-
phone. Each microphone comes with an individual 0° frequency response. The individual compensation curves for 0°
and 90° free-field measurement can be requeed via the following link: www.beyerdynamic.com/mm1-regier
Frequency response curve ± 1.5 dB MM 1 0 dB = 15 mV/Pa
APPLICATION
The MM 1 has been developed for the calibration of
udio rooms, PA and ELA syems. In conjunction with a
spectrum analyser, the sound pressure levels of loud-
speakers can be checked in addition to frequency
response measurements. Due to the slim housing with
the protruding microphone capsule, the influence on
the sound field is very low, so that a pressure build-up at
high frequencies is moly avoided.
The transmission pattern is selected so that an exactly
linear frequency response is achieved with diuse sound
input. This makes the calibration of several loudspeakers
in the udio paicularly easy and fa.
The MM 1 also provides valuable services when
inveigating sound signals in research, development
and indury.

INSTALLATION AND OPERATION
Connection
�The MM 1 is equipped with a 3-pin XLR connector.
You can connect it to any microphone input with
phantom power (12 - 48 V) with a suitable microphone
cable. Activate phantom power for this purpose.
�Caution: Carelessly laid cables are a trip hazard.
People can be injured and the microphone
can be damaged.
Operation
�When setting up the MM 1, make sure that there
are no large objects close to the microphone, which
could influence the sound field and place the
microphone clamp as far down as possible.
�Note on the calibration of loudspeakers in udio
rooms:
When measuring loudspeakers and other sound
sources with a high direct sound level, you should set
up the MM 1 so that the microphone axis is at 90° to
the sound source (see illuration below). This ensures
a linear recording with all frequencies. With direct
sound input from the front, a slight pressure build-up
becomes evident at frequencies above 10 kHz. This
leads to a boo at high frequencies (refer to the
frequency response curve at 0°).
With lower frequencies, there is no pressure build-up
and the polar pattern is exactly omnidirectional.
�Depending on the alignment of the microphone to
the sound source, you should use the appropriate
calibration file. The individual compensation curves
of the 0° and 90° free-field measurement of your MM 1
can be requeed from beyerdynamic free of charge,
ating your serial number: https://www.beyerdyna-
mic.com/formulare/konferenztechnik/mm1-regier
�The MM 1 is supplied with the MA-CL 21 microphone
clamp for tripods with 3/8" thread. For tripods with
a 5/8" thread, you can unscrew the threaded inse.
�Caution: A tripod with an insecure and can fall
over and damage a microphone mounted
on it. Make sure the tripod ands able.
MAINTENANCE
�Use a so cloth moiened with water to clean the
microphone sha.
�Make sure that no water enters the microphone.
�Do not use cleaning agents containing solvents.
DISPOSAL
�This symbol on the product, in the operating
inructions or on the packaging means that
electrical and electronic devices mu be
disposed of separately from household wae
at the end of their life cycle.
�Always dispose of used equipment in
accordance with applicable regulations.
�Dealers for electronic equipment are generally
obliged to take back wae electrical/electronic
equipment free of charge. This obligation also
applies to sales via remote communication.
�For fuher information, please contact the local
authorities or the dealer from whom the product
was purchased.
TROUBLESHOOTING AND SERVICE
�Should you have technical problems when using the
microphone or should you need more inructions,
