SMT process production, small volume design, exquisite and beautiful appearance<br/>2. Single power supply, the tone board adopts a fever level operational amplifier NE5532<br/>3. The separated version of potentiometer is easy to install, and is not limited by the spacing between casings<br/>4. AC/DC dual purpose, more convenient to use<br/>5. Wide application range<br/><span style="font-size:20px"><strong><br/>Parameters:</strong></span><br/>Working voltage: AC3V-16V/DC5V-24V<br/>Board size: 100mm * 45mm (excluding the protruding part of potentiometer)<br/>Overall height of the board: about 23mm<br/>Spacing of 4 potentiometer: 25mm (fixed version of potentiometer)<br/>Input/output signal line length 300mm<br/><br/><span style="color:rgb(255, 0, 0);font-size:20px"><strong>be careful:</strong></span><br/>The connecting wires of the separated version of the potentiometer (two connecting wires of the same potentiometer) cannot be replaced at will, otherwise the work will be abnormal.<br/>The four separate versions of potentiometer may be put together when they are delivered. You can break them when you buy them<br/>The operational amplifier is equipped with a gold-plated circular hole socket. If you feel that the operational amplifier is not hot enough, you can replace it with a better operational amplifier chip yourself<br/><br/><span style="font-size:20px"><strong>detailed list</strong></span><br/>Tone board * 1<br/>Input/output signal line * 2<br/><br/></div></div><p><br/></p>
