Carte de filtrage secteur EMI
La carte de filtrage secteur traite l’alimentation entrante avant qu’elle n’atteigne le transformateur et l’étage de régulation. Son rôle est de réduire les perturbations conduites par le secteur, de préserver la fourniture de courant et de créer une base plus propre pour le reste de la chaîne d’alimentation.

Download the official guide before installation and follow the screw sequence, wiring map, and final safety checks step by step.
Measured Under Controlled Bench Conditions
Ripple noise performance is verified with a dedicated bench setup and then reported under idle and full 2A load conditions, so the upgrade can be evaluated by measured electrical behavior as well as listening impressions.
Montage de contrôle sur banc
The measurement setup verifies the upgraded power path under controlled input, load, and probing conditions before the ripple results are reported below.
Bruit d’ondulation : alimentation d’origine et LPS-T8
Lower microvolt ripple means cleaner current delivery and a darker electrical noise floor.
| Point de comparaison | Eversolo T8 d’origine | LHY Audio LPS-T8 | Résultat |
|---|---|---|---|
| Bruit d’ondulation | Factory PSU reference: 32.09µV | 3.556µV even under full 2A load | Approximately 89% lower ripple than the stock reference. |
| Plancher de bruit à l’état de repos | Stock switching architecture leaves more residual ripple. | 2.557µV static ripple at idle. | Cleaner background before playback begins. |
| Stabilité sous charge | Higher ripple rises against the upgraded linear supply baseline. | Maintains microvolt-level noise at full 2A load. | Stable current delivery with stronger dynamic headroom. |
