Professional Audio Power for Your DIY Home Theater
Upgrade your audio experience with the 2.1 Channel Home Theater Amplifier Board. This robust circuit board is engineered to deliver high-fidelity sound for a complete 2.1 speaker system, featuring dedicated outputs for two satellite speakers (Left/Right) and one powerful Subwoofer. At Robogears, we recommend this board for hobbyists looking to repair old home theater systems or build a custom high-bass portable audio box.
The Power of Triple TDA2030 ICs
This board utilizes three high-performance TDA2030A amplifier chips. Two ICs handle the stereo satellite channels, while the third is dedicated exclusively to driving the subwoofer. This configuration ensures that your mids and highs remain crisp and clear even when the bass is pumping at full volume. To keep the chips cool during long playback sessions, they are pre-mounted on a substantial aluminum heat sink.
Integrated 5V Power and Pre-Wired Controls
Ease of installation is a priority with this design. The board comes with an onboard 7805 voltage regulator, providing a stable 5V DC output that is perfect for powering external Bluetooth modules, USB MP3 decoders, or FM tuners. Additionally, it is pre-wired with high-quality potentiometers for Volume, Bass, and Treble, allowing you to fine-tune your audio profile immediately out of the box.
Key Highlights:
Deep Bass Performance: Dedicated TDA2030 IC for powerful subwoofer driving.
Onboard 5V Supply: Easily power your Bluetooth or USB module directly from the board.
Dual Power Compatibility: Designed to work perfectly with a 12-0-12 center-tapped transformer.
High Efficiency: Low distortion and high signal-to-noise ratio for studio-quality audio.
Ready-to-Install: Pre-soldered wires for speakers and controls save significant assembly time.
Output Power: 15W + 15W (Satellites) + 15W (Subwoofer)
Frequency Response: 20Hz – 20kHz
Supply Voltage: Dual 12V AC (12V-0-12V)
Maximum Current: 3A – 5A
Output Impedance: 4$\Omega$ to 8$\Omega$
Regulator: 7805 (Provides +5V DC Output)
Input Connector: 3-Pin Header for Audio Input
PCB Size: ~100mm x 65mm
Installation Tip: To avoid hum or noise, ensure that the amplifier board and your audio source (Bluetooth module) share a common ground. Using a 12V-0-12V transformer with at least 3 Amps of current will provide the best bass performance and sound clarity
