The product adopts high-quality materials and high-quality tone chips, with high, low, volume, and surround adjustment potentiometers. <br />2. Easy to operate, designed with a direct switch setting. The short-circuit cap on the V side is for tone function, while the short-circuit cap on the G side is for direct connection. The tone is not fixed and can only be adjusted to adjust the volume. <br />3. Single power supply, dual-use of AC and DC, more convenient to use. <br />4. There are fixed and separated versions of potentiometers that can be selected according to needs. The fixed version has a distance of 25mm between the four potentiometers, while the separated version is not limited by the distance between the casings. <br />5. Small size design, with good compatibility, widely applicable to low-cost audio devices, significantly enhancing the surround sound effect.</p> <p>Parameter: <br />Working voltage: AC 5-16V or DC 7-21V (switching power supply cannot be used as it may cause interference) <br />Potentiometer spacing: <br />Fixed version: The spacing between 4 potentiometers is 25mm <br />Separated version: not limited by the spacing between the chassis <br />PCB size: 100mm * 45mm <br />Signal line: approximately 300mm</p> <p>Package include: <br />1. Fixed version of potentiometer: <br />Tone board X1 <br />Signal line X2</p> <p>2. Potentiometer separation version: <br />Tone board X1 <br />Potentiometer X4<br /></p></div></div>
