Great interface, solid all around. Easy set up. the 4k button adds that extra sparkle. Would recommend this highly

Plug & play goodness!
The difference between the SSL and the M Audio interface I'd been using is amazing.
Without out all the tech mumbo jumbo, this thing just plain sounds good!
The preamps are clean, but have a lot of muscle to boost any signal.
An additional cool feature is the '4K' buttons that emulate the SSL 4000 series mixers.
SSL includes a boatload of free downloads & hardware discounts on the SSL plugs, etc.
If someone is on the fence about getting one, just do it, you'll be glad you did.

I have been a long time user of a different Audio Interface for years. I'm not going to name names because I'm not here to bash another company, but my previous 3rd Generation red Interface really didn't like Windows 11 very much, in spite of it's drivers being "Windows 11 compatible." After an hour or so of use, it would start to buzz, or altogether cut out. Even when using it just to play music from my Media player, or to listen to YouTube videos. I wasn't alone in this, because there were all kinds of REDIT posts, Facebook posts, etc., about the exact same problems. The only "solution" people had found was to use a REALLY old driver with it. And while that solution worked, it had its own quirks and issues as well (such as the control app freezing when trying to close it). Anyway, frustrated, I called my sales rep and asked what he would recommend for the price range I was able to spend. He didn't even have to take a second to think about it, and suggested the SSL 2 MK2 line. There are two models of this, the MK2 and the MK2+. The main two differences being 2 or 4 outputs and headphone monitor routing to either of the two SETS of outputs. I only need 2 in my setup, so I went with the Mk2 (non plus). That is the ONLY difference. First thing I loved about this...NO external software app needed to do anything. You can do it ALL right on the front panel of the Interface. And it's easy. The sound quality is GREAT, and best of all....no weird audio glitches like my previous Interface. Oh! And, it's USB powered. I now have a free electrical outlet in my studio. That might not seem like a huge deal...but I actually had a separate line from our circuit box wired directly to my studio because as you know, a good studio setup requires a LOT of power. (Computer, 4 monitors, keyboards, Mixing boards, speakers, external hard drives, lighting, etc.) I have 10 wall jacks, and 2 power strips...and they are ALL full. So now I have one extra plug to find something to plug in, haha.

Anyway, I've been a fan of SSL for quite a while. I have all the WAVES SSL plugins, and my good buddy has SSL equipment in his studio and also recommended this product.

I couldn't be happier.

I just got this to replace 2yo Black Lion Revolution 2x2 which the drivers for Windows were getting wonky already. SSL is a nice unit, took some ironing out for cracks and pops, adjusting sample rate and buffer size. The slight CONS are the unit remains ON even with my laptop turned off, so I have to unplug it. And secondly I find it odd that the two monitor out jacks are so close together!! It makes it tight and awkward to plug in the cables. Still, I would buy it again, just a couple minor irritations. Thank you Jimmy Hart for all you do!!

I recently got the SSL2 Mk2 interface and all I can say is wow! I'm using an older AT4050 and I thought it sounded fine, but through this interface, I was astonished at how much better it sounds. There is so much more detail and full frequency bandwidth. The bundled plug-ins are great – no junk. I've always wondered what was the big deal with SSL, and now I know. If you are looking for an affordable interface, this is definitely best in class.

With the 4K mode engaged, it sounds very much like the larger SSL consoles!

This is by far my favorite audio interface.
Vocal sounds so beautiful! I wished I bought the one with more input.
If you want to go up from this go for apollo but if budget is your problem get this!

When I first got the SSL2 I had a little trouble with the setup only because my other 2 channel interfaces ( Focusrite 2i2, Volt 2) didn't require me to switch channels in my daw. I am really happy with this unit and the fact it has loopback for directed sessions. Sound quality is good with good micpre amps although I use a Grace 101 for my mic. I like the 2 headphone jacks since I have a set of headphones in the booth and one set where I do my edits for VO. Quiet, solid build, and easy to use. This interface does have a bigger footprint than my other interfaces but not a deal breaker.

Headphone volume has improved and the 4k mode you can actually hear the difference in this version! Easy to use. Priced right.

High Five!

Overall I've enjoyed the SSL MK2 audio interface. Its functionality and ease of use is top tier. Having different knobs and buttons for just about everything makes the recording process and small adjustments so much easier. The mic outputs are also on the back which I love. The only thing I don't like as much is the size and physical feel. It feels cheaper than I expected and is definitely chunkier than other interfaces. Hopefully in the long run, the preamps, quality, and use makes it much more worth it!

I love this interface, and all of the specs that it lists are a massive increase in quality from what I used to have (Scarlett 2i4). However, the casing feels like a significant portion of it might be made from plastic. That's a little disappointing, to be honest, because I was expecting something that felt a little heftier and substantial. That being said, the layout is very convenient and the individual channel phantom power is wonderful. I quite like the interface overall.

Why I chose SSL 2 MK II:
1. Studio preamps and headphone amp.
2. 32-bit Analog-digital-analog converter
3. USB Class compliant = plug n play on Macs and iOS devices
4. Dual parallel front headphone jacks
5. 2 Auto-detect Instrument channels on the front (no need for DI boxes)
6. 2 Rear combo XLR jacks for Mics, Line level instruments, and 48V phantom powered mics
7. Stereo/Mono playback switch
8. Preamps strong enough to run a Shure SM7B without an additional signal booster

Extra goody: DC-coupled outputs can supply +/-5V to CV controlled devices, such as USB synths, keyboard, etc.

HISTORICAL REASON to choose SSL: This interface contains the same preamps as used in the big SSL studio consoles.
Why is that a big deal? Historically, SSL consoles recorded more records in the 20th century than any other console brand.
Sinatra, Nat King Cole, and on and on were recorded using SSL consoles. Therefore, I have great faith in their preamps and quality.
