ZK 3002 Stereo Amplifier Board 600W Subwoofer Power TPA3255

Experience powerful, clean audio with the ZK-3002 Stereo Amplifier Board, a high‑power digital power amplifier designed around the TPA3255 chip. Perfect for subwoofers and compact DIY audio projects, this board delivers dynamic, studio‑quality sound with efficient heat management and flexible configuration. High‑quality inductors engineered for high current, low magnetic loss, and minimal parasitic capacitance preserve signal integrity while reducing heat. Oxygen‑free copper wiring enhances sound quality and provides strong EMI shielding. A thickened, enlarged heat sink paired with solid‑state electrolytic capacitors ensures reliable performance even during long listening sessions. Note: color may vary slightly due to monitor settings. With one‑click bridging you can switch between BTL stereo (2×300W) and PBTL mono (up to 600W). The board also features temperature‑controlled automatic cooling or manual fan control to keep temperatures in check, and flexible input options (defaults to left channel in PBTL mode but can accept both channels for more complex setups). Built in a sturdy PC housing, the ZK‑3002 is designed for durability and easy integration into your audio rack or DIY enclosure. It operates from a DC power supply in the range of 18–50V (53V max) with recommended 36–48V, >10A of headroom. At intercyprus.com since 2002 — trusted for quality and reliability.

Benefits & Tips

• Versatile power for subs and stereo setups: Use the BTL mode for stereo listening or bridge to mono in PBTL for up to 600W to drive a subwoofer with clean, dynamic bass.
• Smart cooling for long sessions: Rely on temperature‑controlled cooling or the optional fan to maintain performance during extended use.
• Flexible inputs and gain control: Default left‑channel input in PBTL with support for dual‑channel input; adjust gain with the 10‑position potentiometer (26–36 dB).
