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, \u0026gt;10A of headroom.
