This Class D dual channel amplifier board from Yuan-Jing employs a Texas Instruments' TPA3116D2 amplifier IC to deliver maximum power with minimum distortion. Each channel is rated to deliver up to 50 watts (into 4Ω loads) when this amplifier board is used with a 24 VDC, 6A power supply. We recommend this 24 VDC power supply. Gain is fixed at about 26 dB.
The high-quality, multi-layered PCB prevents circuit damage due to accidental spills while protecting users and nearby-placed components from the risk of shock. AM interference is built into the TPA3116D2, as-is short-circuit protection, thermal protection, over/under-voltage protection, and DC protection.
High quality components such as 1% tolerance metal resistors, MKP-film box capacitors, shielded inductors, and thick copper traces used throughout this Yuan-Jing amplifier board to ensure signal integrity from input to output. Screw terminals make power and speaker connections quick and easy, with a 12" lead included for the line-level input.
