I just bought
the Audiobox 1818vsl. I was torn between this and the Roland Octacapture. I also own a Zoom r16, which is sort of the "ginsu knife" of recording interfaces (it slices, it dices, it can cut through a tin can, etc., etc.)
I got
the Audiobox because it was about $300 cheaper than the Octacapture, and IMO Presonus makes the best pre-amps in the "under $1000" range. Sure there are better mic pre's than Presonus, but you're going to pay over a grand for them. 115db Dynamic Range is sufficient for what I need and the pre's are very, very quiet, especially compared to my Zoom r16 where the pre's have about 85db dynamic range, and you start to hear noise with the pot tuned half way to full. On the Presonus, I have to turn the pot to almost 3/4 of the way before I hear anything, and even then it's pretty subdued.
I'm glad that Presonus is finally starting to develop more for USB, because despite all the fandom Firewire is going the way of the dinosaur. yeah it's still around, but even Apple is going away from it. Plus the Presonus, allows for 16 inputs through ADAT, so it's really one of the best USB interfaces in this price range, but that doesn't mean it's perfect.
The good:
Like every presonus device, the mic pre's are incredible especially in this price range.
You can control with an iPad, with the free app, from Presonus
Built like a tank, the chassis is all metal solid design, including the pots. It's rackmoutnable and truely road worthy, for those using in a live
venue.
VSL is really great, and simple an easy to use. A ton of presets, that are drag and drop. You can add multiple scenes, for a live show.
Minor gripes:
pretty cool that you can control this with an iPad, but you are still tied to having a computer, and a wireless router with you, if you're at a gig, and using it live. No support for Android users unfortunately, and no word on when they might port the app.
Probably a better option is if the GUI will integrate with all the new touch screen laptops that are coming out, or a device like microsoft surface pro that will be able to load the driver direct on it, with a USB out, and a touch screen interface.
The device is setup to work with the DigiMax D8, but the way the 1818vsl is designed with the combi - xlr/1/4" inputs on the front, and the pots on the front, all the outputs on the back, but
the Digimax has the XLR only inputs on the back of the unit (only two 1/4" line inputs on the front), could make for a cabling nightmare. Maybe not a big deal to some, but I'm a little anal about that sort of thing. I just wish there was more of a group design in mind, when making these products, since they're designed to work together.
Honestly, for the price I paid, I have few complaints. It's a well built, well engineered piece of hardware, and the sound quality is about 100 times what I get from my Zoom, and some of the mics I'm using aren't even that great. It's really the quality of the mic pre's and how quiet they run, that just makes for a strong signal with clear response. And don't get me wrong because I still love the Zoom for what it does, and it's portablility. I just needed more than 2 channels of phantom power for some of the room mics I use.
