Creative Analog Character

Soundcraft Ghost mic preamps deliver smooth overload behavior and rich harmonics, paired with Sapphyre EQ for musical tone shaping. Built-in dbx one-knob compressors with harmonic enhancement and insert points provide flexible sound shaping.

Exclusive Lexicon Hardware Effects

As the only console in its class with a built-in Lexicon hardware processor, Signature Plus 12 adds preset Store and Tap Tempo functions for expanded creative control.

Advanced Talkback To, Listening and Metering

A dedicated Listen bus allows engineers to monitor channels without interrupting the main mix, while Talkback To routing ensures clear communication where and when needed. Extensive SSM (Simple Success Metering) provides fast visual feedback across all inputs and outputs.

USB-C Connectivity For Modern Workflows

A 4x4 USB-C 192kHz interface enables seamless playback and recording with laptops or mobile devices. USB inputs can be routed into channel strips or override the mix for break music and DJ sets. Additionally, single press select empowers direct headphone and control listening between sessions.

Simple, Flexible Monitoring

User-configurable monitoring controls include independent headphone/control room outs, with Mute / Dim / Mono Sum, and user selection from Auxes, Listen, Mix, or direct USB returns for streamlined monitoring precision per listener.
