Chris Lord-Alge is a five-time GRAMMY®-winning mix engineer who has Green Day, Keith Urban, Madonna, and Rod Stewart amongst his clients. He has recently upgraded Studio A at his MIX L.A. complex for Dolby Atmos® work, facilitated by an interface and converter infrastructure based on Focusrite RedNet components. The Dante®-networked RedNet setup helps interconnect two Avid Pro Tools workstations and a new 9.1.4 Ocean Way Audio speaker system with Chris' beloved Solid State Logic SL4064E mixing console.
Lord-Alge has had to rethink his long-established workflow with the addition of the new immersive audio capabilities in Studio A, but with encouragement from various industry colleagues, he says, “I decided to make the leap into the unknown and finally eliminate all the vintage gear that was connecting my audio to the console."
Improving performance and sound
For many years, Chris' mixing workflow required projects to be initially transferred to a 48-track Sony DASH tape machine, which he favoured for the performance of the converters and the metering (he eventually eliminated all use of tape and just used the machine's converters). He has now replaced that machine with a Pro Tools HDX rig, operating at 96 kHz/48-bit, that feeds a pair of Focusrite RedNet HD32R 32-channel HD Dante network bridges. Using Dante Controller, Chris selects the tracks for distribution over the Dante network through four Focusrite RedNet A16R MkII 16-channel analogue interfaces and into the mixing desk. His stereo mix from the console is then routed back through one of the A16R MkII units and an HD32R HD Bridge and captured in the Pro Tools computer.
The converters in the A16R MkII units offer a noticeable improvement in performance over the DASH machine, Chris says, plus he no longer has the hassles of his former setup, where he had to synchronize the DASH machine and two Pro Tools rigs. “Once I figured out what level worked and the headroom, I found the sound of the A16R MkII was much better and clearer and more open," he reports.

A dedicated Dolby workflow
A second Pro Tools system is now dedicated solely to mixing in Dolby Atmos, which is natively 48 kHz/24-bit. “I get a great stereo mix of the record with all my colours of analogue gear and an analogue console, and we break that out. Once I've done my stereo mix and I've created all the stems I need for Atmos, into computer number two they go. So, my Atmos mixes are made from stems that are created with all the vintage outboard gear. Then computer number two with the Dolby renderer becomes my second playback system," stated Chris.
“The second Pro Tools system doesn't need I/O because it's all in-the-box," he continues. “All I need is one RedNet PCIeR Card, which gives me 128 channels over Dante at 48/24, connecting through a Mac Mini as the Dolby renderer. So Pro Tools can send 128 objects to the renderer and the monitoring. None of this would be possible without RedNet."
While it does take some time to print all the stereo stems from his mix and create a session for the second Pro Tools system for mixing in Atmos, Chris says, “At this point in time, that is the way that works for me. I use the Atmos computer and the renderer for the object placement and the three-dimensionality of the mix. But for the actual nuts and bolts of creating the sonics inside the mix, I use my stereo rig."
“The Focusrite support is undeniably amazing, because it's one of those things that, once you get the puzzle pieces correct, it boots and works every time."
The MIX L.A. complex is now fully wired for Dante and RedNet, he says. “The whole room is networked with RedNet and so is my new studio next door. We can capture from there; they can capture from here. I'm able to use Dante to connect to my other studios and move forward into the future. And it works seamlessly."
Lord-Alge, who by his own estimate has mixed more than 25,000 tracks in stereo, admits that he is a Dolby Atmos novice: “I am completely a newbie. But I'm learning about the future, about how it works and what can be done." To that end, he says, he has received welcome support from the Focusrite team in the US.
“The Focusrite support is undeniably amazing," Chris says. “Because it's one of those things that, once you get the puzzle pieces correct, it boots and works every time. But you have to understand how it works, and I didn't."
Letting your ears decide
He does have some reservations about some of the Atmos music mixes that he has heard, though. “As soon as you go into Atmos with some records, everything's exposed. Once you start to unglue it, it doesn't have the same impact that you remember and it becomes more about, 'Wow, I never heard that part.' Well, maybe you weren't supposed to hear that part. And this is the problem I have with it. I feel that a lot of records have been pulled apart and have revealed the ugly side of the song, not the good side."
Live performances delivered in Dolby Atmos in a theatre could provide the best listener experience, he believes. “I feel you should be able to go into a theatre and hear these live concerts remixed in Atmos and take advantage of the three-dimensionality of it. Because when you're in a concert, it is three-dimensional. So, if you could actually do that in a theatre, I think it'd be exciting."
Chris may be a relative beginner where immersive music mixing is concerned, but he is determined to be successful at it: “I like to win. I like to have the edge. And the only way to stay ahead is to find your own path with Atmos," he says. “I'm just letting my ears decide what works. But you know, it's a fun ride every day, so I'm enjoying it."
