Note: RS20i Analog in and out 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.
