MM 1 — Condenser Measurement Microphone 5
EN
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,

� 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.
