Note: RS20i Analog channels are designed to be balanced, not single ended, for highest sound
quality. If wiring single ended, wire only to (+) and ground. The (-) side of the channels should
not be connected. Do not short the (-) sides of the channels to ground, which will degrade sound
quality and cause the RS20i to overheat.
