D-702
Class-D Power Amplifier
The D-702 is a class D amplifier delivering a minimum output power of 2 x 70 Watt into 8 Ohm.
The amplifier is constructed using two pre-mounted amplifier modules.
The power supply is splitted, each channel has its own rectifier and buffer capacity (60.000 µF per channel).
When mounting 19 holes are to be drilled and the power supply board has to be mounted with only few components. Wiring is done with only 10 wires.
