In our Audio ABC, we offer you easy-to-understand glossary articles on key terms and topics from the world of hi-fi - compact, informative and ideal for deepening your knowledge of sound, technology and devices.
M
Type of loudspeaker based on the principle of electromagnetic induction. They use a thin, lightweight membrane film that is moved by a magnetic field to generate sound. This technology enables precise and detailed sound reproduction with low distortion.
A moving coil cartridge for record players uses moving coils to generate an audio signal. It offers particularly precise sound reproduction, but is more expensive and requires special amplification.
Thin, flexible layer in loudspeakers that converts sound waves into mechanical vibrations. These vibrations then produce the sound we hear. The quality and properties of the membrane can have a major influence on the sound reproduction.
The moving iron cartridge of a record player uses a moving iron core to generate an audio signal. It offers a sound quality that lies between MM and MC cartridges.
"Musical Instrument Digital Interface, a communication protocol that enables electronic musical instruments to communicate with each other. It transfers information such as notes, tempo and control commands between devices. MIDI is often used to control and synchronize music production, recordings and live performances.
Speaker responsible for the reproduction of mid frequencies in an audio system. It is usually positioned between the tweeter and the woofer and ensures balanced sound reproduction. The midrange driver enables clear reproduction of voices and instruments in music.
Mid refers to the frequency range between bass and treble, typically between 250 Hz and 2,000 Hz. This range includes important sounds such as voices and many instruments.
Magnetic pickup used in record players. It uses a moving coil to convert the vibrations of the record into electrical signals. MM stands for moving magnet, as the magnet in the cartridge is movable and the coil is fixed.
Mono refers to the playback of audio via a single channel. Unlike stereo, which uses two channels, mono reproduces the same audio signal on all speakers.
A monoblock amplifier is an amplifier that is only designed for one audio channel (left or right). Two monoblock amplifiers are often used in stereo systems to operate the channels separately and more powerfully.
MP3 stands for "MPEG-1 Audio Layer 3" and is a common audio format for compressing music files without significantly impairing the sound quality. It enables high sound quality with a comparatively small file size, which makes it easier to store and transfer music. MP3 files can be played on various devices such as computers, smartphones and MP3 players.
Audio system that makes it possible to play music in different rooms at the same time. Multiple speakers can be linked together to provide seamless sound reproduction throughout the home. By using wireless technologies such as WiFi or Bluetooth, users can conveniently control music via an app or voice commands.
