NONDK TDA7498E 2.0 Digital Power Amplifier Board 160Wx2 High Power Stereo Amplifier Support for BTL 220W with Cooling Fan

3. Temperature Control Fan: The fan uses a temperature control scheme that is -saving, environmentally friendly, and low noise. The industrial grade temperature control fan has low noise and good heat dissipation effect, providing protection for high-power heat dissipation (the temperature of the heat sink is high enough for the fan to operate and force heat dissipation) 2. Support BTL Mode: Short circuit of J1, J2, J3, J4 on the back of the power amplifier board) 36V power supply, 3 ohms mono 220W output (TDA7498, TDA7498L chips do not support this function 4. Fever Capacitor: Symmetric capacitor design, 12 fever capacitors, 470uf x 12=5640uf. High quality inductor, inductor with low heat generation and high sound quality. 1. TDA7498E Chip: TDA7498E is a dual channel digital audio power amplifier IC with high efficiency and high fidelity, which is widely used in audio equipment. This chip has the advantages of low distortion, high output power, and low power supply voltage, making it suitable for power amplification applications in various audio systems. 5. Heat dissipation method:temperature controlled forced air cooling (when the temperature of the heat sink reaches a certain level and the fan is running for forced heat dissipation)
