ABsolute PA Mono

Class AB
Monophonic
Power Amplifier

There are amplifiers that impress with watts, others that seek elegance as their strength. And then there's ABsolute PA Mono, which transforms energy into living, palpable, and engaging music. 500W in class AB aren't here to impress on paper, but to unleash every nuance of the performance, every breath, every emotion of the recording.

From the first listening, ABsolute PA Mono imposes its presence with naturalness: the control is total, the silence between the notes is deep, the dynamics explode without ever losing elegance. The low frequencies are solid and authoritative, the medium rich and material, the high range is open and bright, always refined. Everything flows with a fluidity that makes you forget about electronics, leaving room only for music.

Its monophonic core, generous power supply, and obsessive attention to every constructive detail create a broad, stable, three-dimensional sound scene, capable of filling the space and engaging the listener at the center of the musical event. There is no effort, no compression: only authority, control, and freedom of expression.

ABsolute PA Mono is designed for those who are not content to hear, but want to listen. For those seeking an amplification capable of moving, surprising and making every listening session an intense and definitive experience with any type of loudspeaker or musical genre.

Audio Analogue ABsolute PA Mono: power that gives voice to emotions.

Technical
Description

Circuit without global feedback.

All stages are fully balanced.

ABsolute PA Mono is polarized in class AB up to 500W on 8 Ohm.

The bridge output stage accommodates 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 asymmetrical and operates in current with no global feedback.

Oversized military resistors to minimize thermal distortion.

Audiograde capacitors.

Balanced stereo input.

Microcontroller management.
