Which is better TDA7560 or 7850?
1. TDA7850: 4*50W MOSFET Quad-Bridge Power Amplifier with HSD 2. TDA7560: 4*45W QUAD Bridge Car Radio Amplifier PLUS HSD Both of them have HSD, which is the difference in power, and the difference is only 5W.
Car amplifier TDA7560 original with 4 ohm speakers: Question 1. Now a certain channel directly adds a treble (4 ohms), and 4 ohms and 4 ohms become 2 ohms. Will the output power change? (That is, the total volume of this road is larger than the other). Question 2. Before connecting a treble, connect an extra 2 divider. Is the output change the same as that of question 1?
The tweeter cannot be directly connected in parallel with the original speaker. It is not only the impedance problem and the power change, but the power marked by the tweeter is the power that can be tolerated at high frequencies. If it can also withstand the bass, it will not work at all. The output power of the power amplifier is mainly in the bass part, the treble power is very small, and the speaker impedance changes with the frequency. Big, the volume is slightly louder and hangs up. Although an LC divider is not necessary, a capacitor should be connected to divide the frequency at most. For example, a non-polar capacitor between 2.2 and 5.6uf will basically not change the output power of the entire power amplifier after it is connected, and the volume will basically remain unchanged. The tone should be more delicate and translucent.
What kind of integrated block is TDA7560? What's the use?
TDA7560 is a car power amplifier block, its main function is to improve the sound of the car and ensure the quality of the sound.
Can I replace D7388 with TDA7560 for car audio? Do I need to replace the capacitor?
The pin function is the same as the arrangement, and it can be replaced completely. Just after the replacement, if the power cannot reach or the sound quality is not good, it belongs to the power supply voltage does not meet the requirements of the new block. There is no need to change capacitors.
Is it feasible to replace TDA7388 with TDA7560 power amplifier block?
The parameters of the two are not much different (the power of 7560 is slightly larger), and the pins are the same, which can be directly replaced.
