Power - 400 Max x 4 @ 2 Ohms, 200 Max x 4 @ 4 Ohms, 800 Max Bridged x 2 @ 4 Ohms. Full Range - With a Full Range amplifier you not only have the option to run your speakers, but also your subwoofers. Variable 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. 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 Low-Pass Crossover - Subwoofers reproduce sound based on a number of different low-range frequencies. You can set exact sound specifications for the bass frequency reproduction. Fixed High-Pass Crossover - Speakers reproduce sound based on high, low or mid-range frequencies. The High-Pass Crossover gears specifically towards “highs” in all size speakers including mid ranges and tweeters. Bridgeable - Dramatically increase the power output to you speakers and subwoofers by connecting two amplifier channels. Specs - Dimensions: 11.93” x 7” x 2.39”, Weight: 5.75 lbs..
