Rotel's RSS-900 answers the dilemma faced by many audiophiles seeking a combination of multi-speaker convenience in addition to accurate and transparent signal transfer from an amplifier to a single pair of high resolution speakers. Five pair of speaker outputs benefit from Rotel's unique Impedance and Anti-capacitance Compensation to preserve sound quality while protecting your power amplifier from the potentially difficult conditions that can otherwise arise when driving multiple pairs of loudspeakers. The sixth output pair ("Direct"), designed for the main system speakers, has minimal effect on the critical amplifier-loudspeaker interface. The RSS-900 provides yet another example that Rotel's Balanced Design concept brings you convenience without sonic penalty.
