Compact and versatile. The Radial SW4 is the perfect tool for quick noiseless switching between two balanced signals with intuitive front panel controls. Each of the four channels features XLR inputs and transformer-isolated outputs eliminating the detrimental hum and buzz from ground loops. Adjacent channels can be linked together for stereo 3-way or even 4-way switching and multiple SW4s can be used together for even larger systems. Two dedicated 1/4 outputs and a top-mounted mono switch allow you to quickly convert the SW4 for use with guitars. The units outputs can handle signals up to +20dB at all frequencies without distortion making it perfect for use with high-output sources and systems. PFL switches and a built-in high-performance headphone amplifier allow you to monitor any channel at any time ensuring consistent seamless playback. For a powerful flexible and intelligent switching solution for live-performance and concert applications the SW4 is the ultimate choice.
