Gryphon Essence Preamp

Start-Up Level vybere a uloží do paměti výchozí nastavení hlasitosti, které bude předzesilovač automaticky nastavovat při každém zapnutí.

Level Matching lze přednastavit tak, aby automaticky odpovídal úrovním vašich zdrojů. Přizpůsobení se provádí pomocí zeslabovače hlasitosti, přičemž v cestě signálu nejsou žádné další komponenty.

Green Bias (aktivní pouze v případě, že je Gryphon Essence připojen k výkonovému zesilovači Gryphon prostřednictvím řídicí linky Green Bias). Green Bias umožňuje automaticky přepínat mezi provozem v 50%, 75% nebo 100% třídy A bez degradace zvuku.
