This unit is equipped with a bi-amp mode to enable a complete bi-amp connection using two SC-11 S1s. This complete bi- amp connection is a high-end technique for enhancing sound quality, proposed by Marantz. Using this system, the bi-amp supporting speaker system is separated from the preamplifiers that separately drive the low and high speakers.
