1. Wide voltage range: DC12-26V
2. Efficient Class D amplifier board, both more than 90% of the power efficiency and low idle loss characteristics,advanced modulation system configuration,multiple switching frequencies prevent AM interference.
3. TPA3116D2 Advanced Oscillation / PLL,the circuit uses multiple switching frequency options to suppress AM interference;with the Master-Slave mode option, you can also synchronize multiple devices.
4. TPA3116D2 device for short circuit, overheating, overvoltage, undervoltage, and DC and other faults provide comprehensive protection. In the case of an overload, the device reports a failure condition to the processor, preventing itself from being destroyed.
1. Digital amplifier circuit overload capability is much higher than the analog amplifier.
2. Digital amplifier only work in the switch state, will not produce crossover distortion.
3. Digital amplifier speaker speakers do not match the time to consider the problem of internal resistance.
4. Digital amplifier conversion without using any template to enlarge the feedback circuit, thus avoiding the transient intermodulation distortion.
1. Using four brand-name resistors, 4000F 35V large capacity capacitors, filter and stable voltage performance is excellent.
2. Use of European-style terminals, more high-end, the appearance of the atmosphere, wiring locking more firmly.
3. Adopt sticky type individual radiator, M3 screw fixed, heat dissipation efficiency is better and firmer.
4. FR-4 glass fiber 1.6mm double-layer system board. Ultra-high strength crossing, to meet DIY design.
