TDA7297 AC DC 7-12V Audio Power Amplifier Board Dual Channel Bluetooth 5.0 Class Amplifier Receiving

1. TDA7297 renowned amplifier chip, dual channel delivering 15W x 2, exceptional audio fidelity. 2. Dedicated audio Bluetooth reception, no call interruptions, privacy assured, 10 meter extended range. 3. Excellent performance, 91dB signal-to-noise ratio, minimal background noise, crisp and pristine sound. 4. Compact size and appearance, suitable for mini audio modification and assembly. 5. Plug and play design, simply connect the power and speaker to produce sound, easy and convenient to operate. TDA7297 is a classic 2.0 power amplifier chip, known for its excellent performance and high fidelity high-power output. In response to market demand, we have incorporated a mini Bluetooth module using this chip to form a smaller Bluetooth amplifier. When you connect the power and speaker to your hand, it immediately emits sound, giving you a Bluetooth speaker and freeing you from wired constraints. The Bluetooth module is specifically designed for pure audio reception during programming, without functions such as calling or receiving. Incoming calls can be answered directly with a mobile phone, avoiding interference with others and effectively protecting your call privacy. After the call ends, music continue to play automatically.
