Soundcraft Signature Plus 12 Analog Mixer with Lexicon Effects and USB-C

The Soundcraft Signature Plus 12 Analog Mixer with Lexicon Effects and USB-C is built for live engineers, musicians, producers, podcasters, and content creators. Its 12 input channels combine Ghost mic preamps, Sapphyre EQ, and dbx one-knob compressors, giving you hands-on control over gain, tone, and dynamics. Built-in Lexicon hardware effects add further processing, with Store and Tap Tempo functions helping you manage effects settings.

A 4x4 USB-C interface handles high-resolution recording and playback with laptops or mobile devices, making it easier to combine analogue mixing with software-based workflows. Four Aux sends work alongside Mix to Auxes, a dedicated Listen bus, and selectable Talkback To routing for flexible monitoring. Simple Success Metering provides clear visual feedback across inputs and outputs, while colour-coded buttons and tactile controls help you find settings quickly. Rack ears are also included for fitting the mixer into a suitable rack setup.

Shape sources with analogue character

Soundcraft Ghost mic preamps give you a solid starting point for connected microphones, providing smooth high-gain behaviour alongside harmonic character. Sapphyre EQ then lets you shape individual sources to suit your mix. Built-in dbx one-knob compressors simplify dynamics control and add harmonic enhancement, making them particularly useful for voices and acoustic instruments. TRS insert points provide another option when external processing is needed, letting you bring compatible processors into individual signal paths. Together, these controls give you several practical ways to manage gain, tone, and dynamics without making the channel strip unnecessarily complicated.

Bring Lexicon effects into your mix

A built-in Lexicon hardware processor gives you effects directly from the console, reducing the need to add a separate effects unit to your setup. Store functionality lets you retain presets for later use, while Tap Tempo provides hands-on timing control for suitable effects. The processing sits alongside a purpose-driven control layout designed to make everyday adjustments easy to find. Colour-coded buttons help distinguish different functions, tactile squircle-shaped knobs make controls easier to identify by touch, and smooth faders provide precise level adjustment — particularly useful when you're working quickly on stage or in reduced lighting.

Record and play back over USB-C

The integrated 4x4 USB-C interface brings computer and mobile-device connectivity directly into the mixer. It supports 44.1kHz, 48kHz, 88.1kHz, 96kHz, 176.2kHz, and 196kHz sample rates, giving you several options for high-resolution recording and playback. USB signals can be routed through channel strips, letting you incorporate playback into the wider mix. Alternatively, USB can override the mix for uses such as break music and DJ playback. Direct USB returns can also feed the monitoring section, helping you move between analogue sources, recorded material, and computer playback without adding a separate audio interface.

Manage monitoring without disrupting the mix

Four Aux sends and Mix to Auxes give you flexible tools for creating and controlling monitoring feeds. A dedicated Listen bus lets you check channels without interrupting the main mix being sent to performers or your audience. When you need to communicate, Talkback To routing lets you choose where talkback is sent. Headphone and control room outputs offer configurable monitoring with Mute, Dim, and Mono Sum controls, alongside selection between Auxes, Listen, Mix, and direct USB returns. Simple Success Metering runs across inputs and outputs too, providing quick visual feedback while you're working.
