  • Page 32 Is the LUCIA power stage inherently bridged as on E Series, thereby allowing asymmetrical loading? to use power on one channel that is not being used on the other, as with Lab.gruppen’s E Series. However, the channels are automatically optimized when it comes to peak voltage, enabling one channel to deliver the full rated power into 2 ohms and the other channel into 8 ohms.
