<div class="detailmodule_html"><div class="detail-desc-decorate-richtext"><p>Features: <br/>1. 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/><br/></p></div></div><p><br/></p>
