EMI-filterkort for AC
AC-filterkortet behandler nettstrømmen før den når transformatoren og reguleringstrinnet. Formålet er å redusere nettbårne forstyrrelser, opprettholde strømleveransen og gi resten av strømforsyningskjeden et renere utgangspunkt.

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.
Oppsett for benktest
The measurement setup verifies the upgraded power path under controlled input, load, and probing conditions before the ripple results are reported below.
Rippelstøy: original strømforsyning mot LPS-T8
Lower microvolt ripple means cleaner current delivery and a darker electrical noise floor.

|---|---|---|---|
| Rippelstøy | Factory PSU reference: 32.09µV | 3.556µV even under full 2A load | Approximately 89% lower ripple than the stock reference. |
| Støygulv i inaktiv tilstand | Stock switching architecture leaves more residual ripple. | 2.557µV static ripple at idle. | Cleaner background before playback begins. |
| Stabilitet under belastning | Higher ripple rises against the upgraded linear supply baseline. | Maintains microvolt-level noise at full 2A load. | Stable current delivery with stronger dynamic headroom. |
