- The Soundcraft Signature Plus series includes four analog consoles: 12, 16, 22, and 32 channels.
- Preamps Ghost, compressors dbx OverEasy and Sapphyre EQ are identical from one model to the next: the sound does not depend on the format you choose.
- Each console features a USB-C 4 x 4 audio interface up to 192 kHz, enough to record a mix or power a stream without extra gear.
- So the choice comes down to the number of channels and where the console will live, between mobile rig and fixed installation.
Since the Soundcraft Signature Plus series arrived in stock, we’ve been asked quite often which model to choose. And each time, the answer starts with good news that might first sound like a disappointment: all four models sound the same. Same preamps, same compressors, same effects engine, same audio interface. What changes is the format, meaning the number of sources you can plug in and where the console will be set up. In other words, it’s not a quality choice, it’s a stage choice. We’ll go through the series in order, from 12 to 32, with what each one concretely offers.
Comparison of the four Soundcraft Signature Plus mixing desks
The order below is by format, not a ranking: none of these four consoles is a downgraded version of another. You can also see all four Signature Plus side by side before diving into details.
The four Soundcraft Signature Plus consoles, model by model
The Signature Plus 12 opens the series, and Soundcraft didn’t design it as a stripped-down version. Its 12-channel format targets setups that need to stay portable without giving up seriousness: demanding rehearsal, small stage, recording, permanent installation in a multipurpose room. On stage, you get the next-generation Ghost preamps with 65 dB gain, enough to boost a dynamic mic without pushing the fader to the bottom.
It’s also the series model that fits content work best. The USB-C 4-in/4-out audio interface makes it a central hub between analog and computer: mixing a voice, music, playback, and an external source, then sending it all to a live stream or recording session. The independent Listen bus lets you check a source on headphones while the main mix keeps going.
Pros
- 12-channel format designed for rehearsal, small stage, and recording
- Next-generation Ghost preamps, up to 65 dB gain
- Built-in USB-C 4 x 4 audio interface up to 192 kHz
- Assignable talkback to auxiliaries and outputs
Cons
- Computer recording limited to 4 tracks via USB
- Format to size honestly if the stage is expected to grow
The 65 dB gain of the Ghost preamps isn’t just a nice spec. It’s the headroom that lets you make a dynamic mic speak when placed far from the source, typically an announcement or a guitar amp miked off-axis, without blowing the mix.
The Signature Plus 16 is the model you pull out when the 12 starts to feel tight. Four more channels, written like that, seems little. On a band stage, it’s the drums going from two mics to four, or the stereo keyboard finally finding its place without forcing someone to unplug. Soundcraft positions it as a console for setups that need both audio quality, flexibility, and a build that can handle heavy use.
The dbx OverEasy analog compressors on the mono channels really make sense in this context. Stabilizing a voice, controlling a bass, smoothing a snare drum: these are exactly the moves you repeat during soundcheck, and having them on the channel strip avoids lining up racks behind the console. The Sapphyre EQ completes the setup with a musical behavior, precise when you need to correct quickly without altering the source.
Pros
- 16-channel format for the mobile sound engineer and project studio
- dbx OverEasy analog compressors on the mono channels
- Musical and quick-to-adjust Sapphyre EQ
- Independent Bus Listen for pre-listening without touching the mix
Cons
- Same 4 x 4 interface as the rest of the series
- Wider workspace to fit in a mobile control room
Starting with the Signature Plus 22, you change usage category. It’s no longer a console you pack up between gigs, it’s a control room station. Soundcraft targets it at schools and conservatories, multipurpose halls, places of worship, and mobile event control rooms: places where ease of use matters as much as audio quality, because it’s not always the same person setting up behind it.
Advanced output management becomes crucial at this format: the more sources there are, the more you need to route cleanly to the front of house, monitors, and recording. The high-visibility LED meters on inputs and outputs help you read levels at a glance, even in a dimly lit control room. The Lexicon effects engine, with its Tap Tempo, user memories, and bypass, remains instantly recallable from one event to the next.
Pros
- 22-channel format for fixed installation and event control
- Advanced output management
- High-visibility LED meters on inputs and outputs
- Lexicon effects engine with Tap Tempo and user memories
Cons
- 4 USB tracks both ways, for 22 mixing channels
- Size that requires a proper control desk
The dbx OverEasy compressor is there to control dynamics, not to squash them. Set it during soundcheck, with the musician playing in front of you, rather than on a playback that’s already compressed: it’s the live dynamics it has to handle, not those of a file.
The Signature Plus 32 is aimed at setups where sources pile up: a full band with miked drums, monitors, speakers, a playback, sometimes all on the same night. Soundcraft presents it as a console for sound engineers, technicians, and organizations needing a reliable and complete mixing station, capable of handling many sources with real control over dynamics, monitors, and effects.
The enhanced monitoring section is what makes this format manageable day to day. The independent Bus Listen lets you check a source without disturbing the main mix, and the assignable Talkback to auxiliaries and outputs keeps communication open with musicians and crews. The robust chassis, designed for intensive professional use, makes perfect sense on a console that stays installed and is handled by multiple people.
Pros
- 32-channel format for setups with many sources
- Enhanced monitoring section, Bus Listen and assignable Talkback
- Advanced output control section
- Robust chassis for intensive professional use
Cons
- The 4 USB tracks don’t cover multitrack recording channel by channel
- Size of a 32-channel console, plan accordingly before ordering

FAQ - Choosing your Soundcraft Signature Plus
What’s the difference between the Signature Plus 12, 16, 22 and 32?
The format, mainly. The number after the name indicates the size of the mixing surface, and everything else stays the same from one model to another. You don’t move up in range by going up in format: you move up in number of sources.
Can the Signature Plus serve as an audio interface?
Yes. All four models include a USB-C audio interface with 4 inputs / 4 outputs, up to 192 kHz. Enough to send a mix to the computer, get sources from software, record a demo, or feed a live stream. For archiving each channel separately, you need to look at multitrack USB audio interfaces: here, you get 4 tracks both ways.
Do you need to add external effects?
Not necessarily. The built-in Lexicon processor covers reverbs, delays, and modulation effects, with Tap Tempo, user memories, and bypass. Enough to dress a vocal, air out an instrument, or add depth to a mix without adding a rack. External processing is still possible, but the console handles a complete performance on its own.
Is Talkback really useful on a small setup?
As soon as there is more than one person on stage, yes. The Talkback can be assigned to auxiliaries and outputs: you can talk into a musician's monitors without going through the front of house. In rehearsal, recording or events, this is what saves you from having to cross the room to say a few words.
Which format to choose for a band playing indoors?
A standard band fits on a Signature Plus 16. With a brass section or multiple monitors, the 22 breathes better. The 32 makes sense when the console stays installed and sees different setups every week.
The three questions to ask yourself before choosing your format
How many sources, really?
The reflex is to count the musicians. The right reflex is to count the cables. A seriously miked drum kit rarely takes fewer than four inputs. A stereo keyboard takes two. The computer return, playback, announcement mic and last-minute guest always show up just when you thought you had finished the list. Write it down, then add two channels. This is what separates a smooth soundcheck from a game of musical chairs on the XLRs. While you prepare the patch, keeping a few XLR mic cables handy prevents ending the night borrowing.
Where the console will live
A console that moves every week and a console screwed into a control room don’t have the same constraints. On the move, the compact format wins: less surface to protect, less time to cable, an installation that fits in a tight slot. Fixed, the logic reverses. The wide desk becomes a comfort, because each source keeps its dedicated channel and the person taking over finds the patch exactly where it was. The 22 and 32 are designed for this second case.
What you plan to record
The 4-in / 4-out USB-C audio interface is a point to consider early on. It’s made to send a mix to the computer, get a return, feed a stream or capture a live performance. If the goal is to leave with a clean mix the same evening, it’s exactly the tool you need. If it’s to archive each channel separately for remixing the following month, better to know before ordering.
When two formats are close, take the bigger one. A free channel costs nothing the day you don’t use it; a missing channel costs an unplug in the middle of a set. And since the audio processing is identical across the series, stepping up buys space, not a different sound.
So, which one for you?
The shortcut is one sentence: the 12 for a compact station that also serves as an audio interface, the 16 for a band or mobile sound engineer, the 22 for a control room that sees a lot of people, the 32 for a stage that doesn’t break down. You can’t go wrong on the sound, only on the number of channels. If you’re still unsure, size up the series by browsing the analog mixing desks section, and check out the rest of the Soundcraft catalogue.
