60W Audio Amplifier Board TDA2050 + TDA2030 2.1 3-Channel Subwoofer

Description

Audio Amplifier Board 60W TDA2050 + TDA2030 2.1 3 Channel Subwoofer

The bass is powerful and the high notes are not harsh. Use of the chip as new original: the default bass unit for 1 TDA2050– peak output of 32 W, dual channel unit for 2 TDA2030 – peak output of 18 W + 18 W. TDA2030, LM1875, TDA2050 can be fully interchangeable, if all replaced with TDA2050 or LM1875, switch to a larger heat sink.

Tutorial: How to use Audio Amplifier Board 60W TDA2050 + TDA2030

The 60W Audio Amplifier Board TDA2050 + TDA2030 is ideal for those who want to create a simple yet powerful home hi-fi system. With its three-channel design, it offers a total output power of 60W (32W bass + 18W left + 18W right), making it perfect for stereo speakers.

What you need

• Arduino Uno or compatible
• RCA audio connections
• Speakers 4-8 Ohm
• Heat Sink

Steps

1. Connect the board to the heat sink, checking the datasheet for the required heat sink dimensions.
2. Connect the potentiometer to adjust the volume at the board’s audio input.
3. Connect the RCA cables from the audio line to the board and the speakers.
4. Select the power supply voltage (12V-18V) and connect it to the board, checking the datasheet for specific requirements.
5. Ensure all connectors are properly soldered to avoid interruptions or short circuits.
6. If necessary, replace the TDA2030 chip with a TDA2050 or LM1875 to increase the power output of the center channel.
7. Adjust the board controls (volume and crossover) until the desired audio is achieved.
8. Test the entire system with music from an audio player.

Mini project

Create a small stereo bar at home or in offices by connecting the TDA2050 + TDA2030 amplifier board to two speakers and a subwoofer. Use an MP3 player as the audio source.

Common mistakes

• Use an incorrect power supply voltage
• Do not connect the heat sink correctly
• Overload the channels with unsuitable speakers

Recommended accessories

• Large heat sink of 120mm
• 4 Ohm stereo speakers
• 8 Ohm subwoofer
• Potentiometer for volume control
