AUDIO ANALOGUE A CLASS
All our products are covered by Italian warranty.
Second-hand, in good condition, without scratches. Supplied with remote control, no original package.
Two toroidal, 400VA transformer, one per channel. Dual mono design. Pure class A operation up to 50W @ 8 Ohm. Only double-sided metallized polypropylene film capacitor in the critical points. The internal stages are DC coupled and the offset is reduced by means of an integrating amplifiers. High current capability. The protection and control sections are galvanically insulated from the analog sections to minimize the digital noise. No mains fuse. The mains current is measured at the input of the transformer (with a current probe) and in case of malfunctions it's shutted off. The voltage of both channel is measured by means of optocoupler to avoid any ground loop. The DC offset on the output (loudspeakers) is also monitored by means of optocouplers. The protections are realized with a PLD (Programmable Logic Device), more fast and reliable compared to a microcontroller.
