The Radial SW8 Mk2 is an 8-channel stereo passive switcher designed for live sound, broadcast, and studio applications. It allows you to easily switch between two sets of stereo sources for each of the eight channels, making it a versatile tool for managing audio signals.

The Radial SW8 is an eight channel redundant switcher designed primarily for live concerts where backing tracks are used to reinforce the performance. Should the primary playback machine suffer a failure, the SW8 can switch to a backup machine either automatically, manually, or by remote control. The SW8 lets you select between two groups of eight audio inputs and route either group to eight discrete outputs. Input connections are made with your choice of standard eight channel 25-pin D-Sub connectors or individual ¼" TRS phone jacks for easy interface with a variety of audio playback systems. Choice of outputs include an eight channel balanced line-level 25-pin D-Sub or eight transformer isolated miclevel XLR outputs. Most system techs employ the D-Sub output to feed their personal payback system for monitoring and use the front panel XLR outputs to connect to the mic splitter and snake system for the PA.

Key features include:

- 8 stereo channels with independent level control for each.

- Passive design ensures zero coloration of audio.

- No power required, meaning it’s easy to integrate into any system.

- High-quality construction with a sturdy metal chassis for durability.

- Front-panel switches for intuitive operation and quick toggling between sources.

- LED indicators to show which source is active on each channel.
