Radial SW4

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 allows you to quickly and easily convert the SW4 for use with guitars. The unit's 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.

Scenarios and Applications

Noiseless Switching for Live Performance

With the ability to connect and switch between a multitude of sources, from wireless systems to stereo sound sources and consoles, the SW4 is a powerful device with superior operational flexibility. Each of the unit's four channels is equipped with XLR inputs and transformer-isolated outputs, eliminating the hum and buzz from ground loops. Each channel is able to accept two balanced signals, allowing you to toggle between them using a front panel switch or a remote control such as the Radial JR2 (not included). Trim controls allow you to make sure that both of your sources are perfectly matched and supported whilst LED indicators to display when a signal is present.

Adjacent channels can be linked together, opening up the possibility of stereo, three-way, or even four-channel switching with the capability to expand even more when using multiple SW4s together. Each output is capable of handling signals up to +20dB at all frequencies without distortion, enabling seamless operation with high-output devices and systems. The SW4 is even equipped with a built-in headphone amplifier, allowing you to listen to the active input, standby input, or the built-in stereo bus using the 3-position PFL switches on each channel.
