    PPENDIX CS-08 MODULE OUTPUT CONNECTIONS The SP-8 console's monitor module has electronically balanced output circuits on its main output channels. Care should be taken when installing or testing these circuits to avoid connecting the "low" side of these outputs Note these output connection to ground or to an input circuit that has a low impedance to ground.
