Designed as both a standalone mixer and an emergency backup system, the Formula Sound Shadow automatically takes over signal routing when powered on, allowing a venue to keep audio running in the event of a mixer failure. Housed in a compact 1RU rackmount chassis, it provides four stereo channels, a microphone input, headphone monitoring and a crossfader while maintaining the low noise and high headroom Formula Sound is known for. The Shadow can also operate independently in mobile, installation and small venue systems where a straightforward, reliable mixer is all that's required.
