Product features

1. Using 2 pieces of American TI-TPA3255 original power amplifier modules, the output power separation is much better than a single piece.
2. The front-end differential input circuit uses boost technology, which makes the listening experience more dynamic than the official single 12V line.
3. Fully shielded, low-loss sealed inductor, imported filter capacitor.

Product indicators

Output power: 200W+200W/8Ω 600W+600W/2Ω 315W+315W/4Ω
Frequency response:20HZ-30KHZ
THD+N: 0.006% at 1W/4; < 0.01% at clipping
Supply voltage: positive 19V to positive 52V
PCB size:138*128mm

Note: The higher the input power supply, the greater the power supply current and the greater the output. The power test is measured at 50V power supply. If you switch to a 24V 36 low voltage power supply, the output power will be reduced accordingly.

Technology
TPA3255 is a high-performance Class D power amplifier that combines Class D efficiency with truly high-end sound quality. The device features advanced integrated feedback design and proprietary high-speed gate driver error correction (PurePath Ultra-HD). This technology enables the device to maintain ultra-low distortion across the entire audio frequency range, delivering impeccable sound quality. The device operates in AD mode, with a maximum output of 600W×2/2Ω or 300W×2/4Ω, 200W×2/8Ω loads, and features a 2 VRMS analog input interface, seamlessly compatible with high-performance DACs (such as TI's PCM5242). In addition to its excellent audio performance, the TPA3255 also offers the advantages of high power and ultra-low standby power consumption (less than 2.5W), achieved through an 85mΩ MOSFET and an optimized gate driver solution. Compared to traditional discrete implementation solutions, this approach significantly reduces standby power consumption.
