The Soundcraft Signature Plus 12 is a next-generation console in the Signature Plus Series that delivers professional workflows and flagship features at a competitive price. As an evolution of the acclaimed Soundcraft Signature Series, Signature Plus models integrate an unprecedented feature set and unmatched price point. Designed for versatility, these consoles are ideal for studio engineers, live performers, podcasters, and content creators alike.

Available in a 12-channel input configuration, Signature Plus 12 offers consistent audio performance and functionality.

Signature Plus 12 sound quality rivals consoles typically priced much higher. Advanced audio features include a flat frequency response, Soundcraft Ghost mic preamps, Sapphyre EQ, and dbx one-knob compressors with harmonic enhancement. An exclusive, built-in Lexicon hardware effects processor—now with preset Store and Tap Tempo—expands creative control, while combo jack inputs, inserts, and an included software bundle support modern hybrid workflows.

Professional features once reserved for higher-end consoles are now standard:

• Extensive SSM (Simple Success Metering) for both inputs and outputs for fast visual feedback
• Pro Listen bus and “Talkback To” routing for flexible monitoring
• 4x Aux sends including Mix to Auxes for versatile monitoring control
• 4x4 USB-C 192kHz interface for seamless playback and recording with laptops or mobile devices
• User-configurable monitoring controls, included on headphone and control room outs: Mute / Dim / Mono Sum, Aux monitoring, Listen bus, and direct USB routing

Rugged construction and a surface-mounted QR code, linking to training videos, manuals, and support resources, ensure Signature Plus models are ready for any environment. Rack-mount ears are also included with the Signature Plus 12.

The Signature Plus 12 isn’t just another analog mixing console—it’s a professional-grade creative hub that empowers artists, engineers, and creators to deliver exceptional sound in studios, on stage, and across streaming platforms.
