Sorry, Google極都無zone 2可以代替pre out資料, 但美版menu有以下一段, 試吓 :
To turn on Zone 2 and select an input source, press the [ZONE 2] button repeatedly.
Alternatively, press the [ZONE 2] button followed by an input selector button within 8 seconds.
Zone 2 turns on and ZONE 2 indicator lights up.
*To select the same source as that of the main room, press the [ZONE 2] button repeatedly until “Z2 Sel: Source”appears.*
