As an evolution of the ABsolute integrated, ABsolute Monoblock is the flagship amplifier of Audio Analogue. With its 100W of pure class A, it is able to drive at maximum performanceany type of speaker while maintaining the typical refinement of the pure class A.
Power, control, infinite power reserve and all the tonal refinement of the pure class A. An absolute reference amplifier able to give the maximum for every listening parameter.
TECHNICAL DESCRIPTION
Inductive power supply consisting of toroidal transformer and a toroidal inductor for branch designed specifically for ABsolute Monoblock.
Overall feedback free circuit.
All stages are fully balanced.
The ABsolute Monoblock is polarized in Class A up to 100 W on 8 Ohms, so it dissipates about 370 W in heat. The bridge output stage features twelve pairs of transistors, each 200W.The amplification stage is a further improvement of the SeGeSTA structure, which has already been used in the Anniversary series.
The structure is deliberately asymmetric and works in current, without global feedback.
Oversized traditional mounting military resistors to minimize thermal distortion.
Capacitors for audio use.
One balanced monophonic input.
Managed by a microcontroller.
