PANASONIC / WP-DN700 2-channel power amplifier

The WP-DN700 is a 2-channel power amplifier. It uses a Class D amplifier circuit and a switching power supply to significantly reduce power loss and achieve space-saving design. It also features a muting circuit to prevent pop noise when the power is turned on and off. The speaker protection circuit cuts off the output to protect the speakers if an abnormality occurs in the output circuit.
