Input Type
R2c has Binding post type connectors and lets bi-amping/bi-wiring. Bi-wiring can enhance the overall transparency of your loudspeakers by using separate speaker wires for the low and high-frequency drivers from a single amplifier. Bi-amping, on the other hand, involves using separate amplifiers for the high and low-frequency drivers, potentially resulting in a greater dynamic range and reduced distortion.
