Just a quick follow up to my last post, if anyone is interested.
I received the UMC1820 in the mail yesterday via US postal service and I was really surprised it got here that quickly. This was my first purchase from Thomann and it seems to be a great company. My order was fulfilled and shipped really quickly and I can't believe it got here in just 5 days. They were quick to respond to my question regarding the power supply and they provided shipment tracking updates via email.
The unit is incredibly small (shallow) for everything it can do. My Scarlett 18i20 is at least twice as deep. I also own the ADA8200 and the build quality on this feels and looks superior to me. The ADA8200 is definitely a step up from older units (I have an old rack mount mixer and headphone amp), but similar to them in style. The UMC1820 has a really nice matte finish for the main chassis with rounded edges and the rack ears seem much thicker and more durable. The inputs, knobs and buttons are also rock solid. Sometimes knobs can feel really cheap, with a little wiggle room and pots that turn too easily, but these knobs are very smooth and solidly in place.
The external power supply it came with was a standard 2 part brick and cable power supply, not a wall-wart like I was expecting, but this is much better.
It came with a 2-pin European plug, but it looks like you could plug in a standard non polarized US power cord to the brick. The specs on the power supply are 100-240V~ input, 50/60Hz 600mA Max, so I believe it should work fine. However I had already purchased a wall-wart power supply from
Amazon for just $12 (with tax), so it was worth the extra cost. With free shipping from Amazon, that brings the total for the unit up to $236, which isn't bad. For what it's worth, I contacted Behringer (Music Group) about getting a replacement power supply and they replied very quickly with a quote. Unfortunately, it was over $50, so I didn't think it was worth it. The power supply just needed to be 12V 2A output with a 5.5x2.5mm plug.
I haven't had much time to experiment yet, but the UMC Audio Control panel is a little disappointing. I couldn't find any images, video or documentation about it anywhere online, so I may do a quick review video of the UMC 1820 including the software/drivers side. I opened an existing reaper project designed for drum recording with 14 channels for the drums and a ton of plugins to see how this would handle it and unfortunately, I had to crank the buffer size quite a bit to be totally free of pops/clicks. By "quite a bit" I mean I needed a buffer size of 2048! Certainly not ideal, but we'll see how more tests go. Here is a composite image of the UMC Audio Control software including all tabs and pop up windows.
On the Status tab, you can't change anything, it just shows you the connected device and the Current Sample Rate. It appears that there is no way to manually adjust the sample rate setting. When changing the sample rate in Reaper, the UMC 1820 automatically switched. While the automatic switching is nice, not being able to set a default is a little weird to me. Under the Clock Source tab, the Optical In ADAT/SMUX option only appears if the button on the front for OPT I/O is pushed in (selecting ADAT). I haven't tried hooking up ADAT or SPDIF yet. The Buffer Settings tab lets you choose USB Streaming mode from Minimum Latency to "Extra Safe" and the ASIO Buffer size from the usual 64 up to 8192 (with an additional Auto setting). The Volume tab give you access to separate Input and Output pop-up windows with volume, mute and link controls for all channels. The ADAT are, of course, only present if that front switch is pushed in enabling ADAT. Finally, there's the Info tab that shows the Device info and the Driver info.
If anyone has any questions about it, let me know and I'll see if I can answer them. It's nice to finally get my hands on this thing! I'd been waiting for it for a while, but not as long as others on here. I just discovered it late last year around December. I'm glad to see it finally released!
p.s. Supposedly, it's now in stock at
Sweetwater.
