	connector to this port, marked “L” and “R” (left and right) for

CDo not tie both L and R outputs to each other and/or to ground. Doing so will short out the outputs and damage the amplifier.

NThe speaker setup covers two individual speakers of 8 ohm impedance or two pairs of speakers in parallel where each channel drives a maximum output load of 4 ohms
