<p>1. The parameters of the high-power sound quality power amplifier board have been rigorously tested, as long as the wiring is accurate and correct, the sound can be heard, without any debugging by the user</p> <p>2. Eight TOSHIBA chips with fever grade materials create high-fidelity sound quality.</p> <p>3. The power amplifier board thickens the heat sink volume, adopts circuit design, high power, good sound quality, and minimal distortion! The parameters of the power amplifier board have been strictly tested, and the two channels only need to be connected according to the wiring diagram below. It makes a sound without any debugging by the user. The board comes with a filter and rectifier and a heat sink. You only need to connect the power transformer and the front stage.</p> <p>4. Easy and worry-free installation, with rectifier and filter, with speaker delay protection, and with large heat sink</p> <p>5.
