Soundcraft Signature Plus 12 Mixing Desk

Soundcraft Signature Plus 12 — Analog Console with Studio-Grade Signal Chain

This 12-channel analog console from Soundcraft is built around the same Ghost mic preamp circuitry found in the company's flagship live consoles. Every mono channel pairs those preamps with dbx OverEasy one-knob compressors, Sapphyre Asymmetric EQ, and a hardware insert point, so voices and instruments can be shaped from the moment they hit the desk. A built-in Lexicon effects engine, a 4×4 USB-C interface at 192 kHz, and a full monitoring section make this desk equally at home in a club, a house of worship, a school auditorium, or a project studio. The Soundcraft Signature Plus 12 is the right choice for engineers and performers who want the immediacy of analog workflow with the routing depth of a modern hybrid setup.

What Sets the Signature Plus 12 Apart

Two features rarely appear together on a 12-channel analog board at this tier: Soundcraft Ghost mic preamps with +65 dB of gain and dbx OverEasy one-knob compressors on every mono input. The Lexicon hardware effects processor — the only one in this class — adds Tap Tempo, Store, and foot-switch control, so a guitarist or vocalist can trigger FX Bypass and tempo changes without leaving the stage. A surface-mounted QR code on the front panel links directly to training videos, manuals, and support resources, making the console unusually approachable for volunteer operators and students.

Input Channels and Signal Path

The input stage is where this console earns its place in the small-format analog category. Mono mic/line channels feed the Ghost preamps, stereo channels take keys and playback devices, and the switchable Hi-Z input stage accepts electric guitars or basses without a DI box. dbx OverEasy one-knob compressors with harmonic enhancement sit on every mono channel, and TRS insert points allow external outboard processing for more aggressive drum compression or character EQ.

• Number of Channels: 12 — mono and stereo channels with mic, line, and Hi-Z input types
• Mic Preamps: Soundcraft Ghost with +65 dB gain — high-headroom, low-noise design ported from Soundcraft's flagship consoles
• EQ: Sapphyre Asymmetric 3-band — sweepable mids plus high and low shelves

Built-In Effects and Routing Flexibility

Lexicon hardware effects and a deep aux structure give this desk the routing muscle of larger consoles. Four Aux sends plus a dedicated effects send feed stage monitors, in-ear mixes, and the on-board Lexicon engine, while Mix-to-Aux lets engineers blend the main stereo mix into a performer's monitor without rebuilding the routing from scratch. A dedicated XLR talkback input is routable to control room, headphones, or any Aux send.

• Internal Effects: Lexicon hardware processor with Tap Tempo, Store, and foot-switch jacks for FX Bypass and tempo
• AUX Outs: 4 Aux sends plus Mix-to-Aux for flexible monitor mixing
• Listen Bus: PFL/AFL — routes any channel, group, aux, or effects return to headphones or control room without disturbing the main mix

USB Interface, Monitoring, and Build

Modern hybrid workflows are covered by a 4×4 USB-C audio interface that runs at sample rates up to 192 kHz, with USB returns routable into channel strips or directly into the main mix for break music and DJ sets. The monitoring section is unusually configurable for a 12-channel board, with independent headphone and control-room outputs, Mute/Dim/Mono Sum, and source selection from mix, USB, auxes, or the listen bus. SSM (Simple Success Metering) puts three-color LEDs on every input and output for fast gain staging.

• Interface: USB-C, 4 inputs / 4 outputs, up to 192 kHz — pairs with laptops and mobile devices
• Phantom Power: +48 V globally switched across all mic inputs
• Rackmountable: Yes — rack ears included for permanent installation (Dimensions: 341 × 106 × 535 mm, Weight: 6.1 kg)

Who the Signature Plus 12 Is Built For

The Signature Plus 12 is the right choice for live-sound engineers running small-to-mid-size venues, houses of worship, schools, and touring acts who need analog workflow with pro-grade preamps and dynamics on every channel. Podcasters, content creators, and project-studio engineers benefit from the Lexicon effects, the 4×4 USB-C interface, and the included software bundle — Ableton Live 12 Lite, Lexicon MPX and LXP plug-ins, plus the FLUX:: EVO Series Pack and FLUX:: MiRA Session Metering. Volunteer operators and educators will appreciate the color-coded controls, the tactile "squircle" knobs, the SSM metering, and the front-panel QR code that links straight to training material.
