2.0 Digital Amplifier Board Module Strong High Power 300W 300W Class D DC2448V TPA3255

Feature: 1. Original TPA3255: Using the original TPA3255, possess high performance and class D efficiency, which can bring real high end sound quality 2. High Performance Audio Operational Amplifiers: The computing end uses a replaceable DIP-8 op ampx2, and buyers can upgrade the computing model by themselves. This product uses 2 for TI high performance audio operational amplifiers NE5532P 3. Audio Input Coupling Capacitors: The main filter electrolytic capacitor adopts for Nichicon capacity 2200UF/63V x 2, 6 for Nichicon FW series 25V 10UF golden audio input coupling capacitors. Other filter capacitors use for Nichicon series 4. For SAGAMI 7W14A Inductor: Audio digital class D amplifier uses for SAGAMI 7W14A inductor to ensure clear and strong sound 5. Ultra Low Distortion: The device has an advanced integrated feedback design and a proprietary high speed gate driver error correction function (PurePath Ultra HD), this technology allows the device to maintain ultra low distortion throughout the audio frequency band while exhibiting perfect sound quality Specification: Item Type: 2.0 Digital Amplifier Board Material: Aluminum alloy + PCB Model: TPA3255 Working Method: Class D Standby Current: 80mA Work Efficiency: > 90% Channel: 2.0 Rest or Mute: Short circuit mute function Output Power: 315W /4Ω, distortion 10% 185W /8Ω, distortion 10% 260W /4Ω, distortion 1% 150W /8Ω, distortion 1% Frequency Response: 20Hz to 20KHz Dynamic Range: > 100dB Signal to Noise Ratio(SNR): > 111dB Package List: 1 x 2.0 Digital Amplifier Board 1 x Signal Line Note: The indicator light works normally, if the circuit board fails or the temperature is too high, the corresponding LED light will turn off as a warning.
