Loudspeaker processing and amplifying has always been an important part of the APG concept: scientific research based on the mathematical analysis of all the operating parameters of transducers, enclosures and crossovers has provided guidance for the ideas and design of APG processors, starting with analogue electronic technologies through to the dedicated digital processors.



Two ranges of amplifiers are available depending on the needs and their uses:

- The Quattrocanali range dedicated to fixed installations is made up of 2 models: Quattrocanali2404 and Quattrocanali4808, all available in DSP+D.

- The DA range dedicated to live is composed of 2 models: DA8 and DA12.
