Each channel of this Class D dual channel amplifier board is rated at 8 watts, delivered with state-of-the-art sound quality. The TPA3110's efficiency eliminates the need for an external heat sink when playing music under average listening conditions. Integration of high-quality SMD and MKP plug-in capacitors ensures hi-fi amplification output. Requires a DC power supply ranging from 10 to 16V (available separately) and performs admirably with 4 ohm and 8 ohm speakers.
