The Getting Started manual for the UR44 has technical specs but it doesn’t seem to be available as a download.
Here’s a few details for you all.
The manual contained some errors in the specs. I have updated them from an Errata document and highlighted them in red below. I have left the incorrect values and placed them inside { } brackets.

Thanks for posting this - waiting for mine to arrive. I needed the outputs to feed 2 DSLRs along with my mains. Also it will be interesting recording guitars dry with an amp emulated zero latency mix.
Generally in my experience, interfaces in the same line have the same preamps/converters. Unless you have another interface with S/PDIF (and even then), I would choose MIDI over that every time.
I haven’t had a chance to compare specs yet but I suppose it’s due in part to the fact that the UR28M would also function well as a monitor controller. More ergonomic than the typical box layout the UR44 has.
Good point, Bane. Also, iirc, the ur28M can also be operated independently of a computer/iPad, for example as a preamp in a live environment. I don’t know if the UR44 can.
I thought I heard that the UR44 is class compliant but not sure if that means it will work standalone or only powers itself with tablet devices like iPad.
Yeah, class compliant it is. You need to physically switch to CC Mode when using it with an iPad (and switch CC mode off when using a PC/Mac). Also, no USB bus power here. Must be powered with the supplied AC adapter.
I haven’t tried using it standalone but there is no suggestion that this would work. The manual examples are all while the UR44 is connected to either a PC/Mac or iPad. Still, I will give it a go and see what happens…
If everything is armed by DSP, then really it should have a standalone capability. This cannot be marketed as standalone because in the true sense, all DSP routing and FX need to be editable on the device itself without a computer. This is what we have seen with the MOTU and RME interfaces. Normally I’ll just play music through my ipod or keyboard/guitar then disconnect the USB plug and see if it continues, which is how I found out my Scarlett remembers its routing until it’s unplugged from the outlet.
I almost bought that (the 18i20, right?) a few months ago because of the number of inputs and, well, it’s Focusrite so it’s gonna be good quality for the price point. And unless Sam Ash starts carrying the UR44, the Scarlett will probably win eventually since I can put it on my Sam Ash card the next time they run a 12 months or more “same as cash deal.”
Very much so. It really checks all the boxes at my pricepoint and the whole construction seems to be topnotch.
That said, something to consider is that the Scarlett DSP Mixer does not have DSP FX processing capabilities like the UR’s and other big names. There is a design flaw with my 8i6, being that there is no power switch on the unit. The 6i6 and 18i8 were released a week after I picked mine up (and fixed the issue but had no loopback ins). The 18i20 is alright on that though. I would take a Scarlett 18i20 over a UR44 any day.
Depends on what’s important to the user. UR824 has more channels, due in large to it’s extensive digital expansion and again there is a lot of DSP power under the hood. OTOH, the Scarlett definitely has better quality innards, but possibly not enough that you are going to notice in the end. But why do you think the likes of Prism Sound interfaces are held in such high esteem? Because the tech specs of their inner parts are beyond repute.
Personally for my next interface, I’m keeping my eyes on MOTU’s Ultralite MK3, which you may want to give a look Larry. It’s about $550.
