    Hello, the board is only 250W @ 4 ohms maximum. Chinese manufacturers have difficulty understanding that two 250W channels operating in bridge are needed to provide 500W of power. This board is based on the electronic schematic of IRAUDAMP7S, but resistors R13 (100R) and R15 (130k) appear in the diagram with different values, R7 (3.01k) and R8 (120k).

    • @Rtek-zv5lr
      @Rtek-zv5lr 2 роки тому +1

      (For IRAUDAMP7S) NOTE:
      Potentiometer P1A and P1B have been set to zero ohms. This is configured as a 2 terminal variable resistor. This should be set to 200 ohms. This will give a nominal operational frequency of 400kHz for the amplifier module.
      Check the tightness of the devices on the heatsink. (Source: larrynz911)

    Sir Very well explained. Your theory and technical points you shared was of great inspiration to me. God Bless You 🌟🌟🌟🌟🌟🙏. I have personnel question in regard of Rectifier of 0-12 volt trodial transformer it's 75 Amp out. Which kind of bridge rectifier do you recommend and number of capictor and value of capictor. The basic idea to use car power amplifier for subwoofer purpose of bass. Please note transformer is already order and brought from Pune.

    • @WhatIThink
      @WhatIThink  4 роки тому +1

      Please used 100 Amp metal diodes for bridge rectifier. 100uf capacitor for 1 watt of power is required. Accordingly calculate. But it is not good idea to drive car amp from transformer as there will be too much power loss since the same will be again boosted by the inverter circuit inside the amplifier. However its your choice.

Board me fault hai to speaker ud sakta hai. Toh phir for board power on testing me hum kya component laga sakte hai jisse speaker lagane ke zaroorat nahi padegi?
    10E100W resistor in series with 5A fuse laga sakte hai?

  • @amplifierhighwattage7696

    Very good info..... I have used this board. But jyada time ke liye reliable nahi hai. Just wastage of money. Pros-380 watt true rms.Board is small.
    Cons-Voltage is high, risk of electric shock,may damage speaker, Even input audio source. Once damaged repair is expensive or not possible. As one can buy another board in same cost. A small error can damage this board.Power supply is expensive. If voltage is higher by 70-0-70 the board will damage instantly. If the decreases by 220 in home, you can't operate it.
    So Moral-Don't buy this board
