Atoll Electronique PR400 silver

The audio stages of the PR400 were designed with the goal of coupling an extremely wide bandwidth with a perfectly regular phase. This principle ensures an overall coherence that provides total immersion within the sound stage.

The principle of rigorously symmetrical operation, with a specific stage for each alternation and an attenuator per channel, ensures a musical performance full of nuance and detail with an evident ability to separate the performers and the different registers.

The PR400 also has the ability to present a homogeneous musicality regardless of the listening level. The care taken in the smallest adjustments and the choice of components makes it possible to perceive the slightest breath and the intentions of the performers with surprising clarity and naturalness; the most subtle nuances and timbre subtleties are perfectly intelligible.
