The tda7498e and tpa3116 are both good.
TDA7498E Digital power amplifier Board 2X160W stereo BTL220W Mono High power digital power amplifier High power Class D digital power amplifier chip: Original TDA7498E (TDA7498L is 2X80W chip TDA7498 is 2X100W chip, TDA7498E is 2X160W chip) Output power: 2X160W (using 4 ohm impedance horn unit, input voltage 36V DC output power 160W 160W) Working voltage: 15~36VDC DC input polarity is reversed protection.
3116 is louder than 7498, the sound is more three-dimensional. Why do many people think 7498 is better than 3116?
In fact, the two effects are similar, the digital power amplifier is small, the efficiency ratio is high, energy saving and emission reduction, pay attention to the speaker collocation is a very good choice
