  • Extraordinary Gear!
Style: Scarlett 18i20 Configuration: 4th Gen
I am very impressed with this unit. I have only had it for a week or so, but so far I can say it's exactly what I've been needing to get back into recording. I was an original user of the Aardvark audio interface that was way ahead of it's time 20 years ago, and I never fully recovered from it being put out of support. Finding this unit and all it's features and easy connection to something like an iPhone is incredible. Eventually I will get a Mac to use with it, but this thing is awesome. ... show more

  • Better than the Apollo?
Style: Scarlett 16i16 Configuration: 4th Gen
I love this freaking thing dude, has overall given many more paths to explore creatively just by simply having more inputs and outs, instantly noticed a difference in productivity, the upgraded appearance is a plus as well, coming from a gen 3 2i2, I was looking for something to improve functionality and allow me to expand my studio, this has done just that, I would recommend this over an Apollo any day, UAD software can be buggy when dealing with multiple systems, focusrite control is very intuitive and easy to use across the board, not to mention artists vocals sound crisp and clear, smooth harmonic drivers sound beautiful when mixed and gain staged correctly. Overall I’d say this product is worth every single penny and more ... show more

  • Great product
Style: Scarlett 18i20 Configuration: 4th Gen
I upgraded from the Saffire Pro 40 and so far after a couple months i have not experienced any issues with it. It does take some time to get used to the redesigned mixer controlls as it is completely different as the Pro 40, but other then that it is a great product. Reasonably easy to use for someone who used similar products, for someone who is new to recording and equipment, it may take a little longer to figure everything out. It came with a bunch of plug in's and Ableton DAW but you can use almost any other DAW, i use Reaper and MixPad and they work fine. ... show more

  • Everything I need at a fair price
Style: Scarlett 16i16 Configuration: 4th Gen
Focusrite keeps upping the quality and capabilities of their interfaces and the 16i16 is a great example of their commitment to small setups. I have yet to delve into the software but so far as some basic vocals it’s not needed. The dual air modes sound as expected, the mic interfaces are nice and clean, and the bump to 24/192 makes the cost worth it. Then throw in the ability to do routing (up to 96kHz) amongst the extra line ins/outs, optical, and ADAT connections. Perfect for a small studio. The only thing I’m missing from this, that some of the larger have, is the speaker “thump” protection since I have multiple Mac’s and sometimes need to switch my peripherals between them. I do appreciate the ability to provide continuous separate power from the usb. ... show more

  • Flexible, but number of inputs is misleading
Style: Scarlett 18i20 Configuration: 4th Gen
Great sound quality. Excellent for a one person studio because it can be controlled remotely using a phone or ipad app. Doesn't really have 18 inputs unless you use the optical input with an expansion amp. If you're recording drums, plan on buying a second interface.

  • Great

Why did you pick this product vs others?: If you are looking for a good. interface this is it works well. The studio program is way more complicated then what need to be I don't use it.

  • A huge leap from Gen 3
Style: Scarlett 18i20 Configuration: 4th Gen
I was unsure if this was actually “pro level” A/B tested the converters against my Apollo and couldn’t hear a difference in the studio. Actually impressive.
