The D-702 is a class-D amplifier with a minimum output power of 2 x 70 Watts.
The amplifier is configured using two pre-mounted modules. So the builder only has to connect some wires and a few parts on the power supply board.
The power supply is divided in two sections. Each channnel has its own buffer capacity, 40.000 µF per channel.
When mounting some 15 holes have to be drilled. The wiring consists out of 10 wires to be cut and soldered.
