SSL for the Home or Portable Studio with Expanded I/O

Solid State Logic has been one of the dominant forces in audio recording for over forty years, with a legacy of superior large-format consoles, studio outboard gear, and world-class plugin processors. Now, you can have the iconic SSL sound in your home studio with the SSL2+ USB audio interface. The SSL2+ comes stocked with a set of pro-grade preamps, stunning 24-bit/192 kHz converters, and a host of helpful I/O options, including four line outputs, two headphone jacks (accessible on the front and back panel with the option to monitor two separate stereo mixes), and 5-pin DIN MIDI in and out. A unique 4K Legacy mode allows you to add SSL 4000 series analog console magic to your recordings with the push of a button, and an extensive production pack includes the software you need to get started recording instantly. Moreover, livestreamers will appreciate the built-in loopback functionality for mixing your voice with other audio sources before they hit your stream. Recording artists at Sweetwater are big fans of all things SSL, and we’re excited to offer the SSL2+ — an affordable interface with a legendary sound!

Matchless SSL sonics and superior build quality

The SSL2+ interface features the pristine sound and superior build quality for which SSL is known. Equipped with two class-leading microphone/line/instrument inputs and 24-bit/192 kHz converters from industry-renowned manufacturer AKM, the SSL2+ delivers pro-studio sonics in a small form factor. Housed in a sturdy, attractive chassis and featuring Neutrik connectors and Alps pots, the SSL2+ can withstand numerous trips between remote recording locations. The front panel design provides an intuitive workflow with easy-to-read meters and an ergonomically satisfying feel. And, its high-current headphone amp ensures accurate monitoring, so you can be sure that what you’ve recorded is exactly what you’re hearing.

Legacy 4K button for instant analog mojo

SSL built their reputation on their celebrated large format consoles, through which countless hit records and Grammy-award winning albums have flowed. In particular, the SSL 4000 series console has inspired generations of musicians, producers, and engineers with its undeniable analog mojo. The SSL2+ brings that signature 4000 series sound into your project studio with its Legacy 4K feature, which, with the push of a button, imparts the preamps with two essential characteristics of the 4000 series signal chain. The first thing you’ll hear is a musical, high-frequency EQ boost that will push your vocal or instrument forward in the sound field, for a deeper, more dimensional sonic profile. Then, you’ll notice a subtle addition of harmonic distortion that sweetens the sound and adds personality to the signal. For small format recording interfaces, there is nothing quite like the Legacy 4K button, available on the SSL2+.

Bundled SSL Native and third-party software

To get you started recording right out of the box, the SSL2+ ships with a comprehensive production pack that includes Celemony Melodyne; IK Multimedia AmpliTube SE; Native Instruments Hybrid Keys and Komplete Start; Ableton Live Lite; AAS Session Bundle plug-ins; and 1.5GB worth of samples from Loopcloud. In addition to this formidable software suite, the SSL2+ comes bundled with two SSL Native channel strips: Vocalstrip 2 and Drumstrip. With Vocalstrip’s four vocal-specific processors — De-esser, De-ploser, 3-Band EQ, and Compander — you can easily achieve an articulate and impactful vocal sound. And Drumstrip provides five carefully selected processing tools — including transient shaper, drum gate, high- and low-frequency enhancers, and the classic Listen Mic compressor — to add clarity, punch, and heft to any drum recording. Finally, Solid State Logic provides three months of free access to SSL Complete, Auto-Tune Unlimited, and Arcade by Output — a trio of subscriptions that puts the plug-ins of the pros right at your fingertips!

Clean sound, Simple operation, Great value!

I had to replace my 'no-longer-being-made' Apogee Element 24 two channel digital interface (which was excellent!) that originally cost over $800. Money was/is tight and I had to replace that unit in a hurry and couldn't afford the new Apogee models that would suit my needs. The reviews for this SSL 2+ unit were encouraging but I thought that they might be a little hyped, based upon the energy and enthusiasm behind the majority of the reviews. I decided to try it, knowing that Sweetwater would take care of 'things' for me if 'things' didn't work out. No need to be concerned about that! I was amazed at the simplicity of operation and the quality of the preamps and the build! Designed to be immediately compatible with iMac it was literally just 'plug and play' with my M1 Mac mini. I was able to handle monitoring situations In an easier way with this interface than I have ever experienced before. In the past, because of my particular set-up, I was using two different audio chains to monitor the sound while recording, which didn't give me a true acoustic picture of what I was actually hearing/listening to until post-processing. I was accomplishing all of my audio needs within this one unit! Granted, my needs are relatively simple - two channel input and output (singer/songwriter solo guitar) but this unit saved me time and money and actually sounds as good - if not better! - than my much more expensive former setup, taking up much less space and giving me dials and buttons rather than digital apps. I'm 'old school' and prefer manual control over some things - not all - but, some, especially in the recording phase of a project. I'm enjoying much more direct control and much faster changes in balancing inputs, outputs and monitoring. I'm not qualified to give a stat-to-stat breakdown of the functions of this interface but I can tell you that - based upon hearing my results (the ultimate test for any production) - if you're looking for an affordable, small-footprint, great-sounding, versatile, and unique-looking interface, this is one to consider. VERY happy with this purchase! Also: Sweetwater is the BEST! Their customer service 'sets the bar high' for all others. (No, I'm not getting paid nor compensated in any way for this testimonial or endorsement!) Many thanks to Bill Sears, my customer rep. at Sweetwater. To the Marketing Department at Sweetwater - I'm embarrassed to admit that the little bags of candy that are sent along with every order ARE a factor in my ordering decisions and - the very few times that I have had to buy something from another company, when their package arrived - with no candy in it - there was a bit of a 'let-down' that I experienced, increasing my loyalty and desire to order only from Sweetwater! (Now that I think of it....that does raise some concerns about what motivates me.... ; ) LOL!) Even though I have the ability to drive 5 minutes down the road to the store and can buy as much candy as I want (which I 'hardly' ever do!), there is 'something special' about that little collection of sweets that arrives in the bag with the Sweetwater logo on it that arrives with my orders and I welcome that ALMOST as much as the new equipment. : ) Great marketing!!

Music Production

My solid state logic SSL2+ has great sound quality for my music production and it is totally industry standard.BKA turbo houas groove.

Preamps sound good!

The preamps sound good. I couldn't hear a big difference with the 4k switch, maybe a little on the top end. Possibly I will hear more difference in a mix but I haven't done that yet. It works well with Cakewalk Bandlab. There is very little latency and midi also works. Overall it's a good interface and worth the price.
Music background: I started recording in the 70's on a Teac 4 track reel to reel. I have worked in the broadcast televison engineering field since 1983. I have done many recordings over the years with lots of different equipment. I've also produced a few CDs in my time.

Apparently You Can Have It All

The SSL 2+ replaces a nice but terminally glitchy and finicky Audient ID22, and boy, does it! I'm typically skeptical of glowing gear reviews -- buyers typically either love their purchase or hate it. In this case, however, I can't find anything bad to say about the SSL, and I literally like everything about it. Two great pres? Check. Fantastic converters? Check. Two headphone outs? Check. Low(ish) latency via USB-C? Yep. An utterly musical "legacy" mode? Yes. Back-panel connections (so I don't have mic cables, etc. sticking out onto my desk). Rock-solid reliability and idiot-proof setup. I like the control layout, perfect for desktop use.

Okay, the knobs and buttons are plastic, but they have a solid, no-wiggle feel as they turn. I've used Focusrite (2nd & 3rd Gen, Scarlett and Clarett), Presonus, Audient (great idea, bad product) -- the usual pro-sumer level interfaces. The SSL is better than them. It sounds better, it works better, it looks cooler. And the Monitor Level knob goes to 11.

If it's a terrific home-studio interface you're looking for, you can pay more money, but you won't get a better interface.

Extremely Happy!

The 2+ works flawlessly in my home studio. I'm running it on a dual booted PC (Windows 10/Ubuntu) with Jamulus and other online real time "play-together" applications. The extra RCA outputs enabled me to easily integrate the unit into various work flows and desired functions, including using it stream audio and video on a separate machine running Zoom. I'm feeding it's inputs with a mixer. I also tested it running Ubuntu and it worked fine. It seems to me the folks at SSL really got it right. The price/features point is competitively good. Spend a little more and gain a lot. You'll be happier.
