A:Answer Hi Olaf, I believe that the amplifier you're asking about is our model DSP 2-750. Installation is very straightforward with analog inputs and traditional left/right speaker connections. It's unique in that it operates in both 70 volt (750 watts times 2 channels) and 8 ohm (500 watts times 2 channels). It ships in 70 volt mode as it's most often used with our Landscape Series outdoor speaker system. The change to 8 ohm mode is done via our software set up. There is also an optional Digital Input Module (DIM $150) that allows direct connection digital sources. I hope this is helpful, and thanks for asking.
