The completely revised amplifiers of the QUANTUM compact class now offer as V2 version a higher power output and improved features. With a “footprint” of just 150 x 220 mm, the two power plants are completely designed as digital Class D power amplifiers. Their heavy die cast heat sinks contain state-of-the-art technology,, which sets new standards in terms of efficiency up to 90%. With the Auto Turn-On Function coupled to the high-level inputs, the two models are suitable for almost any installation, not only because of their size. Besides the conventional 12V version the Q-ONE and Q-FOUR are now available as 24V version and can be operated in trucks and coaches with a electrical system of 24 volts.
