The RLC-900 solves the two major problems associated with a "plug them into the wall and forget them" approach to system hookup. The RLC-900 provides 9 separate 3 pin (grounded) AC receptacles for system components. Grouped by type (digital source, analog source, power amplifier, etc.), the outlets are sequentially switched to minimize system turn-on and turn-off thumps, They're also heavily filtered to minimize the potentially devastating effects of extreme power line spikes. The RLC-900 also ensures efficient component operation by isolating them from performance-robbing lower-level surges, RFI, and EMI. The RLC-900 is proof that Rotel's Balanced Design approach extends to your whole system, even when a non-Rotel component challenges your quest for the best in sound quality!
