re: SU-X120

Gents, I was thinking of getting one of these as a stand alone unit for my study. However, I don't see how to connect a sub to it. Am I going mad?




Thanks heaps for the manual!! Couldn't find ours :)

Owner's Manual

Is the Owner's Manual/Operating Instructions available for download for the SU-X120? I just bought a pre-loved unit and it sounds great. But there's no manual with it and I don't know how the "Volume Preset" is supposed to work nor what the "Muting" led on the front panel is for (it doesn't seem to do anything).



thanks for putting the schematics up on site really appreciate your kindness
