Unlike the 215, 214, or any in the PLAD200 range, the PLAD412 offers 4 channels, which means less power overall, but more power to more places. It offers an electronic crossover network, gold plated RCA inputs for better sound quality, line outs for left and right channel, low and high pass filter control, power and protection LED indicators, red lighting illumination, and a remote bass level control. The amplifier is 8.6 inches wide, 2.27 inches tall, and 11.4 inches long.
