FANTASTIC, Solidly Featured Mixer
I bought this mixer as an upgrade to the Mackie ProFX8 - I found the 2-track recording on the Mackie limiting at times. I debated whether to keep the Mackie and get a separate multitrack recording interface, but them I came across this mixer. I was more than impressed by it's true multitrack recording capability in both USB and FireWire formats, and for the recording input / price ratio, it just can't be beat. The mixer is loaded with features seldom found on mixers of this size, let alone price point (I'm a HUGE fan of the LED metering per channel - it's been super helpful to reference levels from and almost always is only found on larger format mixers). I also love all of the routing options, with the ability to bring back 4 tracks from my DAW either into the last 2 channels, or straight into the main mix. The sound quality is top notch, super clean and detailed both for recording and playback. Perhaps one of the most impressive features of the mixer for me was the quality of the preamps - they ROCK! I couldn't believe how deliciously quiet they were and how clean they sound. These pre's will make any microphone or source sound fantastic. Overall the build quality is very good, I never feel that any part of the mixer is particularly fragile, and all the knobs have a good-feeling smooth resistance to them. I also like the separate indicators (red and yellow respectively) for Mute and Solo on each channel, one thing that's somewhat bothered me about Behringer mixers in the past. Though there is a lack of detailed documentation / manuals to explain the more obscure features of the mixer (like the quirky Alt 3-4 "subgroup"), the support people at Behringer are extremely helpful and will answer any questions about the features of the mixer. One thing I noticed, though not a bad thing per se, is that at least for my set up, the UFX1204 doesn't play nicely with the ASIO4ALL driver that I use for other interfaces I have. In my DAW, I need to exclusively use the proprietary Behringer UFX driver to get this board to work. So I can only use this board and no other interfaces, or my other interfaces and not this board. Not a big deal for me, but something to note. Also, Maybe it's just my particular setup / computer, but I could not get the FireWire connection to work on my PC. FW works great on my Mac, but not on my PC.
Overall I think this mixer is an absolutely wonderful product and I couldn't be happier with it so far. Definitely worth every penny. If you're looking for a fully featured small format true multitrack recording mixer, this is the ticket.
