2.1 Home Theatre Wired Circuit Board Three 2030 Transistor With 7805

Product Description

The Triple 2030 2.1 Board is engineered for simplicity and durability. It features an onboard bridge rectifier and filter capacitors, allowing it to be powered directly from a 12-0-12 center-tapped transformer. A key feature is the integrated 7805 voltage regulator, which provides a stable 5V DC output specifically to power external Bluetooth modules or MP3 USB decoder boards. The analog nature of the TDA2030A chip provides a warm sound profile that is highly favored for desktop speakers and small TV soundbars.

Key Features

• Triple IC Design: Dedicated amplification for each channel ensures better thermal management and clearer separation between bass and treble.

• Built-in 5V Rail: The 7805 regulator eliminates the need for a secondary power supply when adding a USB/Bluetooth media player.

• Wired Potentiometers: Comes with Bass, Treble, and Volume controls pre-soldered, saving time and reducing wiring errors.

• Heavy-Duty Heatsinks: Each TDA2030A is mounted to an aluminum heatsink to prevent thermal shutdown during continuous playback.

• Easy Repairability: Since it uses standard through-hole components, individual parts like ICs or capacitors can be easily replaced if damaged.

Technical Details

• Operating Type: Class AB (Analog).

• Power Source: 12-0-12 AC, 2A to 3A Transformer recommended.

• Compatibility: Works with 4-Ω to 8-Ω speakers.
