Bemerkungen
 
  
−
Aus Originalpropekt: selektierte, eng tolerierte Bauteile, direkte Signalführung, Leistungsstarker Ringkern-Tranformator. Auch niedrigimpedante Lasten können die RB870BX aufgrund ihrer hohen Reserven nicht beeindrucken, weshalb sie auch schwierige Lautsprecher ohne Probleme ansteuern kann. In Mono-Brückeschaltung gibt die RB870BX eine Kanalleistung von 300 W ab.
