Pure class A
power amplifier

Derived from the ABsolute integrated amplifier, ABsolute PA is a 50W stereo amplifier capable of driving a wide variety of speakers while maintaining the refinement that distinguishes class A.

All the warmth and musicality of pure A class in a reference amplifier that can express itself at its best in combination with ABsolute Preamplifier.

Technical
Description

Fully dual-mono configuration starting from dual power.

Circuit without global feedback.

All stages are fully balanced.

ABsolute PA is polarized in Class A up to 50W over 8Ohm.

The amplification stage is a further improvement of the SeGeSTA structure already used in the Anniversary series. The structure is deliberately asymmetrical and operates in current, with no global feedback.

Traditionally mounted oversized military resistors to minimize thermal distortion.

Internal wiring with pure solid copper 7N OCC conductors, gold plated copper output connectors.

Capacitors for audio use.

Balanced stereo inputs.

Microcontroller management.

Available in natural aluminium and satin black finishes.
