The compact Quantum models Q-FOUR and Q-ONE have been very popular for years, especially when used in combination. This is not surprising, especially since the Class D amplifiers not only impress in terms of looks and sound, but also have a lot to offer with 4 x 100 and in mono up to 700 watts RMS, especially when you consider the small dimensions of only 150 x 50 x 210 mm taken into account. In the new edition of the revised v2 models, they not only offer more features, they are also available as 24 volt versions! So nothing stands in the way of installation in trucks or buses.

With the automatic switch-on function and the modern high-level inputs with EPS protection circuit (in v2 models), connection to modern control devices is also possible without an additional remote cable and lineout. This makes integration into existing sound systems, for example factory systems, child's play. In addition, the v2 models have the latest start-stop technology on board.
