Digital Audio Update

Didja ever notice I kind of go in spurts with posts? I guess that's kind of how my life goes... In little spurts. Anyway...

Nineteen months ago today, I made the move to a digital "board" for mixing live music. At the time, I chose the Mackie DL1608. By-and-large, I've been happy with the Mackie, but there have been a couple of annoyances, most notably the inability to set, save, and recall pre-amp levels from the control application. If you read my earlier post, you'll notice that I knew that going in. So far, my work-around has been to take snapshots of the gain settings for each gig, print them out on a 4x6 card, and keep them in my mixer case. That allows me to set a good starting point for each gig I do with a particular band. But if a pre-amp needs tweaking during a show, I have to run up to the stage and make the adjustment. That's inconvenient for me, and distracting to performers and audience members. Another issue it that Mackie have never come out with control apps for Windows, MacOSX or Android -- not everyone owns an iPhone or iPad.

Other people will be quick to tell you of other shortcomings of the Mackie DL mixers, but really, the pre-amp thing was the part that I found the most troublesome. For instance, I think the reverb and delay, while certainly basic, sound just fine in the real world. And, I've never once had any of the random noise or random disconnect issues that others claim. From day one, the thing has just worked, and worked well, despite its limitations.

Fast forward all these months. Behringer have finally shipped the mixer I really wanted from the start (X-Air X18), as well as a whole host of companion mixers that, better still, are rack-mountable. The control applications have become fairly robust and run on iPads, Android tablets and phones, and also on Windows, MacOSX, Linux, and even on Raspbian! Yes, even on a Raspberry Pi, you can run Behringer's control application. Of course, Raspbian isn't a huge stretch, since it is a fork of Debian. But still. There it is. There may be more about the Raspberry Pi thing at a later date.

Mackie's not been completely asleep at the switch, though. They've put out numerous updates to the Master Fader and My Fader apps, which have added a number of features. But, they do seem to have hit the limitations of the hardware in the DL1608, and even to some extent, the DL32R.

So, I've picked up an XR18 on loan from my friendly nearby Behringer rep./audio gear pusher for evaluation. I've spent about two hours with it so far, and have been really impressed. I've tested with two different laptops running Windows 10, an ancient Dell running an oddball build of Ubuntu Linux, as well as an iPad Air 2, an el-cheapo Android tablet, an el-cheapo Windows 10 tablet, and a couple of rooted and tweaked HTC Thunderbolt Android phones. All have worked flawlessly (though the controls are a little tricky to see and use on the tiny phone and Windows 10 tablet screens).

I like that I can control phantom power individually for each input, as well as choose pre- and post-fader sends on a per-channel-per-aux basis. The general audio quality seems to be excellent (it ought to, as the pre-amps were design by the folks at Midas). And, the effects are pretty stellar.

My impression is that Behringer has done a lot of work on the Android and computer app functionality since I first looked at the demo versions of the app on the iPad almost two years ago. While the Android and computer apps are not as pretty as the iPad variant (nor quite as intuitive as Mackie's Master Fader iPad app), they 've become quite functional, and the current versions mostly make sense.

This is one deep mixer, especially for one that retails for around U$700. I could ramble on for page after page about all the stuff that's crammed into this little box that aren't crammed into Mackie's offerings, but I won't.

You can Google all the tech and comparison stuff, or you can look at this chart that I snagged that sorta shows some of the differences:

There are a lot of things this chart misses, such as the 18 USB returns from the computer which, along with the 18 USB sends to the computer, allow the XR18 (or X18) to act as a full audio and MIDI interface for recording -- at the same time as you're mixing with it. The best you can do for recording with the DL1608 is a two-channel mix, and you have to record to a docked iPad. It also doesn't mention that it's impossible to connect any kind of hardware control surface to the smaller Mackie (they do have a control surface for the DL32R on the way), where any "teachable" control surface (or one that knows Mackie HUI protocols) can connect via MIDI to the Behringer mixers.

One thing that may, or may not, be a sticking point is that there is no app for the iPhone, nor does it look like one is on the horizon. How the heck they let that go by is beyond me, especially given that they support pretty much anything else with a screen. Many of my clients use iPhones, and have gotten used to being able to handle their own monitor mixes. I guess that, since I can get nice, cheap Android tablets for under U$40 each, I could just pick up a few to hand out at gigs. In some ways, that's actually a better scenario, as I can be sure that all the devices being used match the system firmware, and that everything will "play nice".

I'm going to spend another couple of days evaluating, but at this point, I'm thinking that I'll be moving to the Behringer very soon, unless I discover something I just can't live without. I've already got an offer on my DL1608, as well as a couple of other bits of extra gear, so I could probably do this with my only cost being a handful of cheap tablets and another rack (which I've been wanting anyway).
