Product Description

The Solid State Logic SSL 12 is a 12-input USB interface that combines modern and legacy SSL preamp styles with plenty of I/O flexibility in a sleek desktop form factor derived from the SSL 2 and 2+. With more preamps, headphone outputs, line-level outputs, MIDI and ADAT connectivity, the SSL 12 slots perfectly into the gap between streamlined two-channel interfaces and professional rack-mount units. And, with an included software bundle worth more than $1000, this compact interface is the perfect all-in-one solution for solo artists, small groups and project studios alike.


The front panel hosts four premium SSL preamps, each featuring 48V phantom power, a high-pass filter, a five-segment LED meter and a classic SSL gain knob. A “Legacy 4K” button on each channel provides a slight high-frequency boost and finely-tuned harmonic distortion for an edgier sound inspired by SSL 4000 Series consoles. Monitor controls include a main monitor level knob and two headphone volume knobs, as well as three user-assignable buttons that can be used for talkback, monitor switching and more. Premium AD/DA converters provide 32-bit, 192 Hz quality for incredibly high-resolution recording and playback.


In addition to bringing SSL sound to your desktop in high resolution, the SSL 12’s variety of I/O makes it adaptable enough to suit anyone from a synth-based solo artist to an acoustic duo or even a small band. Two switchable headphone/line outputs and four line-level TRS outputs provide separate monitoring for four people, each with individual cue mixes, talkback and near-zero latency thanks to the SSL 360 monitoring software. Five-pin MIDI I/O and DC-coupled analog CV outputs give you plenty of options for controlling synths and effects. An ADAT optical port provides up to eight extra inputs for expanding your setup with an extra bank of preamps. Finally, USB loopback allows you to record sound from your computer easily, a plus for podcasters and streamers.


The cross-platform Mac and Windows SSL 360° application hosts the powerful, yet intuitive console-style SSL 12 Mixer, where you can configure and control every aspect of SSL 12:

  • Easily set up multiple near-zero latency headphone mixes
  • Configure HP A and HP B outputs for different headphone sensitivities or re-purpose as additional line-level outputs
  • Customize the 3 user-assignable front panel buttons
  • Choose your Loopback source
  • Save/Load SSL 12 Mixer templates

If that wasn’t enough, the included SSL Production Pack software bundle gives you access to a plethora of virtual instruments, plugins and DAWs worth more than $1,000. For starters, you get three months of SSL Complete, which provides unlimited access to all SSL plugins. The Production Pack also features premium music-making tools from Native Instruments, Ableton (Live Lite), Celemony (Melodyne), Antares (Auto-Tune), IK Multimedia, Output and AAS.

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.

From the minute I placed my order I was kept well-informed through each step in your process. Even though I was buying a comparatively modest piece of gear, your attention to detail made me feel like I was purchasing a six-figure mixing desk.
