DD-4480 uses a published high-capacity switching power supply with separate amplifier/power-supply cooling, automatic limiting and multiple protection functions. The title states four channels, but some connector and indicator lines mention only CH1–2 even on 4-channel titles, so rear-panel channel count should be confirmed.
