Tosunra Crossover (223XS) is a professional audio tool that helps split your sound into separate frequency ranges for better clarity and performance.
Use it in stereo 2-way mode to send lows and highs to different speakers, or in mono 3-way mode to separate lows, mids, and highs. It has smooth
filters for clean sound, volume controls for each output, and phase switches to adjust speaker timing. A built-in low-cut filter removes unwanted
deep noise, and the frequency range switch gives you more flexibility. With XLR inputs and outputs, LED indicators, and a strong metal case, it’s
perfect for PA systems, live sound, or studio setups.
