Use high quality materials, durable<br/>2. Adopt high-power digital power amplifier chip<br/>3. Small volume design, BTL output<br/>4. Easy to use<br/>5. A wide range of applications<br/><br/><strong><span style="font-size:28px">Parameters:</span></strong><br/>Board size: 50mm*33mm<br/>Operating voltage :DC5V-22V<br/>Output power: 80W (peak power)<br/>Overall height of board: about 13mm<br/>Heat dissipation needs to be paid attention to when a large power is used<br/><br/><strong><span style="font-size:28px">Mute control instructions:</span></strong><br/>M is the mute control terminal, with low level mute and high level working (the control voltage can be from 3v-24v). There is a distribution short-circuit cap, which is in the working state by default when delivering goods and needs to be silent<br/>When controlling, remove the short circuit cap and connect the external control.<br/><br/>You can select one of the following signal input modes:<br/>1: signal balance input (differential) : signal +, signal -,<br/>2: Unbalanced input (single end) : The - end is short-connected to GND(ground). The signal is input from + end.<br/>Note: WHEN UNBALANCED INPUT, IT IS necessary TO CONNECT &quot;-&quot; WITH GND SHORT circuit, otherwise THE sound is abnormal and the chip may be burned seriously.<br/><br/>High power digital power amplifier chip, small volume design, BTL output, high power 80w, single end input, can also balance (differential) input, chip external heat sink work more<br/>Stability.<br/><br/><strong><span style="font-size:28px">Package List:</span></strong><br/>CS8673 digital power amplifier board *1<br/></div></div><p><br/></p>
