This is an excellent DIY amplifier kit for electronics beginners with excellent sound quality. You don’t hear any noise until your ears are close to speakers. This amplifier uses a TDA7297 two-channel amplifier chip.
The TDA7297 is a dual bridge amplifier specially designed for TV and Portable Radio applications.
- No input state, you can barely hear any noise when your ears are close to the speaker. Excellent sound quality.
- The installation of the appropriate size heat sink (not supplied) is recommended.
- The power amplifier board is the core of TDA7297 two-channel amplifier chip, the power supply is designed for DC power supply, 12V battery can be directly powering voltage range: 9-15V is the recommended voltage 12V, the output power is up to 15W + 15W, the peak power of 30W + 30W small volume is super shock for any occasion.
- The amplifier board work efficiency up to 90%, very power-saving with 12V motorcycle battery-powered continuous playback for more than 5 hours.
- The 12V power supply small-size amplifier board deserves to be super power amplifier module, the owner of this amplifier board push two 6.5-inch 100W speaker sound the same lever, a little do not feel hard, the sound quality is super good.
- Thermal overload protection.
- Short circuit protection.
