Purchased new by me a couple of years ago, mainly for the high quality mic preamps, routing options, hi-z inputs for guitar/bass/other instruments to connect directly, but especially for the multi track USB interface (MTK = multitrack) which lets you output channels individually into your DAW. 

Absolute mint condition and working perfectly, this has had very little use. Only hooked up a couple of times to test it out. I’ve just decided to go a different route with my setup. 

Price includes postage. I must have thrown the box out at some point, but I will pack well and box securely to send. 

The Soundcraft Signature 12MTK is a 12-input analog mixing console designed for both live performance and studio recording. Its standout feature is a 14-in/12-out multi-track USB interface, which allows you to record every channel individually to your DAW rather than just a stereo mix. 

Key Specifications & Performance

• Audio Interface: Unlike the standard Signature 12 (which has a 2-in/2-out interface), the MTK (Multi-Track) model supports high-resolution 24-bit multitrack recording and playback.
• Preamps: Features 8 iconic Soundcraft Ghost mic preamps, known for high headroom, wide dynamic range, and ultra-low noise performance.
• Equalization: Includes the Sapphyre British EQ with a sweepable mid-band on every channel, providing more precise tonal control than standard fixed-band EQs.
• Built-in Effects: Equipped with a single Lexicon Effects Engine that offers studio-grade reverbs, delays, choruses, and modulations.
• Dynamic Processing: Includes dbx limiters on input channels 1 and 2 to manage signal peaks.
• Construction: Built with a tour-grade robust metal chassis for long-term reliability.
