Product Description
Features:
1. Dual chip design: TPA3255 is a high-performance Class D power amplifier chip with Class D efficiency and the ability to deliver truly high-end sound quality circuits.
2. Boost differential input: The front-end circuit adopts boost technology, which dynamically performs better than a single 12V line.
3. High quality materials: Full screen shielded low loss inductors and imported filtering capacitors, supporting up to 55V voltage.
4. High efficiency Class D amplifier: supports 600W+600W high-power output, with pure and distortion free sound quality.
5. Ultra low distortion rate: The total harmonic distortion is only 0.006%, and the frequency response range is 20Hz to 30KHz.
Parameter:
Working voltage: DC 19-50V; Current above 5A
Working mode: D-level
Chip: TPA3255 * 2
Output power:
600W+600W/2Ω
315W+315W/4Ω
200W+200W/8Ω
Total harmonic distortion: 0.006%
Frequency response: 20Hz to 30KHz
PCB size: 138X127MM
Attention: The higher the input power supply, the greater the power supply current and output. The power test is measured at 50V of the power supply. If replaced with a 24V/36V low-voltage power supply, the output power will decrease accordingly.
Package Include:
1X power amplifier board
1X adapter
1X terminal wire
