BT30D VS BT30D Pro: MAX Power Output: 50 Watt x2+100 Watt VS 165 Watt x2+350 Watt, Amplifier Chip: TPA3116D2 VS TPA3255. Output: RCA output for powered subwoofers VS 3.5MM full-range output for powered subwoofers and speakers. Just choose one model for your needs. BT30D Pro Adopts 2PCS Texas Instruments TPA3255 high-performance Class-D power amplifier chip. BT30D Pro can drive up to 2 x 175 W into 4-?
Load and 2 x 220 W into 3-? In addition to excellent audio performance, TPA3255 achieves both high power efficiency and very low power stage idle losses below 1 W. This is achieved through the use of 60 m? MOSFETs and an optimized gate driver scheme that achieves significantly lower idle losses than typical discrete implementations.
