BDM8 TPA3255 2x300W Bluetooth5.3 Power Amplifier Board Stereo High Power Audio Amplifier Board Support PC DSP Tuning

Description:
- TPA3255 is a high-performance Class D power amplifier for TI, which has Class D efficiency and can deliver truly high-end sound quality. Unique advanced integrated feedback design and proprietary high-speed gate driver error correction. This technology enables devices to maintain ultra-low distortion throughout the entire audio frequency band while exhibiting high sound quality. In addition to excellent audio performance, TPA3255 also has two major advantages: high power efficiency and ultra-low power idle loss (less than 2.5W).

Bypass Mode:
- Simple Signal Transmission: The audio signal is directly transmitted from the source device to the amplifier through a 3.5mm audio cable, which can preserve the details and features of the original audio signal to the greatest extent possible, reduce signal loss and distortion, and make the sound purer and more authentic.
- Easy to Operate: The 3.5 direct mode provides an extremely convenient connection method. Simply connect the device to the amplifier via a 3.5mm audio cable to quickly achieve audio playback without the need for complex settings and adjustments.
- Wide Compatibility: Almost all modern electronic devices are equipped with this interface. Therefore, the 3.5 pass through mode of the amplifier can be easily connected to various devices and has strong compatibility.
- Suitable for Various Scenarios: whether enjoying music, watching movies at home, or using portable audio devices for small gatherings, outdoor picnics, etc., the 3.5 direct mode can quickly transmit audio signals from different devices to the amplifier for amplification and playback.
- Note:
  1. The total volume potentiometer cannot be used in bypass mode.
  2. Bypass mode cannot perform DSP computer tuning.
  If you want to use these two functions, you can connect the 3.5 input in Bluetooth mode (at the jumper cap).

3.5 Input in Bluetooth Mode:
- Select the 3.5 input in Bluetooth mode, unplug the jumper cap, plug the 3.5mm female wire into the jumper cap position, and turn the dip switch to BT. Not only can you use the total volume potentiometer and DSP Mountain View tuning, but you can also use Bluetooth input by simply unplugging the 3.5mm male wire without turning the switch again. (Insert the jumper cap back when not in use)
