Our Shop-Glossary
Here you will find a summary of all terms used in the shop in one place.
Absorber
An absorber is a room element that is specially designed to swallow (absorb) sound. The use of absorbers is recommended to dampen particularly reverberant rooms.
Active box
Box with integrated power amplifier to drive the speakers. The active speakers in our nuPro series also have a preamplifier for signal processing. See also passive speaker.
AES/EBU
AES and EBU (Audio Engineering Society/Europaen Broadcasting Union) are actually industry associations, but in the hi-fi and especially pro-audio world, AES/EBU refers to a standard for transmitting digital audio signals.
Analog
In analogue audio and video devices, stepless, continuous signals are processed, usually in the form of variable electrical voltage. Unlike a digital signal, an analogue signal is quasi infinitely finely "resolved". See also digital.
ARC
ARC stands for Audio Return Channel. Televisions typically output sound signals to playback devices such as sound bars via ARC. ARC-capable HDMI connections are usually designated as such. eARC is the newer, improved version (e = enhanced).
ATM
Stands for Active Tuning Module. A special electronic circuit from Nubert that extends the frequency response of the designated loudspeaker model and also allows sound control.
AV power amplifier
In a multi-channel system, the AV power amplifier is the device that drives the passive speakers.
AV preamplifier
A device for sound processing in home cinema. Unlike an AV receiver or AV amplifier, it does not have its own power amplifier.
AV receiver
Although there is indeed a slight difference between an AV receiver and an AV amplifier, these two terms are usually used interchangeably and refer to the same device: a combination of (multichannel) preamplifier, power amplifier, decoder and tuner.
