    Some guesses:

    1 overload Overload Indicator Output
    2 amp stby Standby Indicator Output
    3 in l Left Channel Audio Input
    4 gnd Audio Ground (audio return and shield)
    5 in r Right Channel Audio Input

    on the other side
    1 pa-gnd Power Amplifier Ground
    2 hi- out- r Connect your Right Channel Speaker between pins 2 and
    3 low -out - r and pin 3 -probably a bridge output.
    4 +vh
    5 -vh
    6 low out l Connect your Left Channel Speaker between pins 7 and
    7 high out l and pin 8 -probably a bridge output.


    Anybody have a more educated guess?
