    Hi sslome, and welcome to TSG,

    A quick look at the schematic diagrams for the SX1010 seems to show some type deliberate electrical interlocking of the speaker switches to permit only two sets of speakers to be enabled at any one time.

    FYI, Both links result in:
    The SX-1010 does have three sets of speaker outputs. However, the speaker select push buttons are wired such that not all three can be selected at the same time.

    EDIT:
    I am attaching a section of the SX-1010's schematic diagram, showing the speaker switch wiring. I color coded some of the signal paths. The only way to get signal to any of the speakers is if at least one of the speaker selectors switches is in the "Off" position.

    Thanks, I needed to know if it was a problem because I am going to be selling the unit soon.
