Radial Engineering SW4 Overview
Providing versatile channel switching for a wide variety of live applications, the SW4 – 4-Channel Audio Switcher from Radial Engineering features 4 channels, each with 2 XLR inputs that can be stereo linked. Aside from the XLR inputs, each channel can also be linked, supporting tri- and quad-channel switching. Each channel is also equipped with a 3-position pre-fader listen switch that allows you to monitor source A, source B, or the stereo bus via headphones, which can be summed to mono for use with wireless guitar systems.
Channel 1 also features a mix function for summing both inputs together for simultaneous use. The unit has a master bus output, which is fed by all channels. Each channel has its own transformer-isolated output that is capable of handling over 20 dB at all frequencies.
Switching Between Wireless Systems
The SW4 can be used for switching between two or more wireless systems. Use it for backup or to enhance the show without taking up more audio channels. Can also be used on wireless guitars
