This Class D amplifier module is based on a TDA8954 chip, allowing it to develop a power of 2x160W under 4Ω (THD 0.5%), and this with a high efficiency. This amplifier has the particularity of being able to be powered either in DC or in AC, the selection being made via a DIP switch on the PCB. Another DIP switch allows it to use the module in BTL mode and to deliver a power of 420W (10% THD). A 12VDC output is also present, allowing to supply another audio module.
