Full Range - With a Full Range amplifier you not only have the option to run your speakers, but also your subwoofers

Low & High Level Inputs - A low level (RCA) input is measured in voltages. A high level (+/- wire) input is measured in wattages. Both essentially carry signal from your receiver to your amplifier to your speakers

Variable Input Gain Control - The gain control is not for adjusting volume. It simply adjusts the amount of signal that is coming from your receiver and going to your amplifier
