How to Monitor Out of Pro Tools with Onyx 1640i
Honestly, the first time I tried to get my Pro Tools output into my Mackie Onyx 1640i for some actual hardware monitoring, I thought my brain was going to leak out my ears. It felt like trying to teach a cat calculus. You’ve got this fancy digital workstation, and then this totally analog beast, and the connection point feels like it was designed by someone who actively hates sound engineers.
Years ago, I blew about $150 on some fancy digital converter that promised the moon. It sat in a drawer collecting dust after a weekend of nothing but digital pops and clicks and a headache that lasted three days. So yeah, I’ve been there, done that, and have the slightly-too-expensive t-shirt from the experience.
Figuring out how to monitor out of Pro Tools with Onyx 1640i isn’t just about plugging in cables; it’s about understanding signal flow at a level that makes sense, even when the gear seems to be speaking different languages.
Getting Your Pro Tools Signal to the Onyx 1640i: The Main Event
This is where most folks get stuck, and frankly, it’s not entirely their fault. The Onyx 1640i is a FireWire interface, which means it’s got its own built-in digital-to-analog converters and preamps for its inputs, but for outputs from your DAW, you’re essentially using it as a sophisticated analog mixer with a FireWire connection that often gets misunderstood. When you’re trying to monitor out of Pro Tools with Onyx 1640i, you’re looking to bypass Pro Tools’ own output converters and use the Onyx’s for zero-latency monitoring, especially for tracking.
The key here is configuring your Pro Tools playback engine. You absolutely *have* to tell Pro Tools to use the Onyx 1640i as its primary audio device. If you don’t, it’ll keep trying to send audio to your computer’s onboard sound card or whatever else is plugged in, and you’ll just get silence or digital garbage. I remember the first time I did this, I spent about forty-five minutes convinced the mixer was broken, only to realize I hadn’t even selected the correct driver in Pro Tools. Pure idiocy, but it happens.
Once Pro Tools sees the Onyx, you need to set up your output routing. This isn’t as complex as it sounds, but it requires a deliberate step-by-step approach. You’ll want to assign your main playback output in Pro Tools to the digital outputs that correspond to the physical outputs on your Onyx 1640i. This is where the FireWire connection comes into play; it’s how Pro Tools talks to the Onyx’s internal digital routing system.
Understanding the Onyx 1640i’s Role
The Onyx 1640i, bless its analog heart, is fantastic for giving you tactile control over your sound. It’s not just a box to spit audio out of; it’s a place where you can tweak EQs, compressors, and send signals to outboard gear before they even hit your speakers, or, more importantly, before they go back into Pro Tools for recording. This analog summing and routing capability is what makes it appealing for many who want that hands-on feel, even with a digital session running. (See Also: How To Put 144hz Monitor At 144hz )
Think of it like this: your Pro Tools session is a massive, intricate tapestry woven with digital threads. The Onyx 1640i is the loom that lets you physically touch and re-weave some of those threads before they become permanent. It’s not about replacing Pro Tools’ processing power; it’s about adding a different flavor and a different workflow to your audio. The tactile feedback of faders and knobs offers a level of immediate satisfaction that clicking a mouse just can’t match, and when you’re tracking vocals or a guitar, that immediacy is golden. It feels solid, substantial, like a real tool, not just a phantom interface.
Setting Up Your Playback Engine and I/o in Pro Tools
First things first: ensure your Onyx 1640i is powered on and connected via FireWire to your computer. Then, open Pro Tools. Go to `Setup > Playback Engine`. In the dropdown menu, select your Mackie Onyx 1640i. If it doesn’t appear, you might need to install or reinstall the Mackie FireWire drivers. This is a common stumbling block, especially on newer operating systems that can sometimes be finicky with older FireWire drivers. I spent a frustrating two hours once because I assumed the driver I downloaded from a generic driver site was the correct one; turns out, I needed the specific one from the Mackie archive, which was buried six levels deep.
Next, navigate to `Setup > I/O`. You’ll want to focus on the `Output` tab. You’ll see your default outputs. You need to reroute these to match the physical outputs on your Onyx 1640i. For example, if you want your main stereo output in Pro Tools to come out of channels 1 and 2 on the Onyx, you’d map Pro Tools’ ‘Out 1-2’ to the physical outputs that feed channels 1 and 2 of the Onyx. Sometimes, this requires creating new output paths if Pro Tools doesn’t automatically recognize them. It’s a bit like assigning different lanes on a highway for different types of traffic; you’re telling the digital traffic where to physically go.
What About Latency?
This is the big question for anyone trying to monitor through an external mixer from a DAW. With the Onyx 1640i and Pro Tools, you’re aiming for near-zero latency monitoring. The magic happens because you’re using the Onyx’s analog monitoring path. Pro Tools sends the digital signal to the Onyx via FireWire, the Onyx converts it to analog internally (using its own D/A converters), and then you monitor that analog signal through the mixer. Because the signal is already analog by the time it hits the mixer’s monitoring section, there’s no need for Pro Tools to process it again on the way out for monitoring, which is where latency creeps in.
I’ve seen people try to use software monitoring within Pro Tools while still trying to get an analog feed, and it’s a recipe for disaster – double monitoring, phasing issues, and way too much delay to be useful for tracking. The entire point of using the Onyx for monitoring is to leverage its direct, low-latency analog monitoring capabilities. This means you’ll often mute the Pro Tools track you’re recording on if you’re using the mixer for your primary monitoring source, to avoid hearing yourself twice with a noticeable delay. This is a common practice in studios; the engineer handles the headphone mix on the analog console, and the DAW simply sends the audio *to* the console.
My Own Dumb Mistake: The ‘double Monitoring’ Debacle
So, I was setting up a session for a buddy, and he was adamant about using the Onyx 1640i for zero-latency tracking. We had it all hooked up, Pro Tools was seeing the Onyx, and he was singing. Except, he kept complaining about hearing himself late. I’m checking cables, levels, gain staging, everything. I’m convinced it’s his headphones, his mic technique, anything but my glorious setup. Then, after about twenty minutes of escalating frustration on both our parts, I noticed it: the little ‘Software Playback’ button was still engaged in Pro Tools on the track he was recording. We were hearing him through the Onyx *and* through Pro Tools’ software monitoring, with the Pro Tools latency adding that infuriating delay. He walked out. I spent the next hour questioning every life choice that led me to audio engineering. It was a $300 lesson in paying attention to the obvious buttons.

Routing for Tracking vs. Playback
This is a nuanced point but vital for smooth operation. When you are *tracking*, you generally want the signal to go from Pro Tools to the Onyx, and then you monitor the *analog input* of the Onyx directly. This is the zero-latency path. Your Pro Tools session is essentially acting as a tape recorder in this scenario, just capturing the audio. You’re not necessarily listening to the processed signal *from* Pro Tools in this monitoring mode.
When you are *mixing* or just *listening back* to your work, you’ll likely want the signal to come back from the Onyx into Pro Tools. This is where you’d use the analog inputs on the Onyx (channels 1-16, depending on your setup) and route them back into Pro Tools as new audio tracks or bus assignments. This allows you to hear the full mix, potentially with plugins applied in Pro Tools. The beauty of the 1640i is its flexibility; you can route almost anything anywhere, which is also why it can be confusing initially. The insert points on the Onyx are also fantastic for inserting outboard gear directly into your Pro Tools signal chain on the way back in, giving you a hybrid analog-digital workflow.
The Onyx 1640i as an Analog Front-End
Many engineers don’t use the FireWire connection on the Onyx 1640i for monitoring *out* of Pro Tools at all. Instead, they use the Onyx purely as an analog front-end for the microphones, summing its analog outputs into a different, more modern audio interface connected via USB or Thunderbolt. This approach completely bypasses the Onyx’s FireWire driver and its internal DA/AD converters for the Pro Tools connection, relying instead on the external interface for the computer communication. This is a valid and often preferred method if you’re experiencing driver issues with the Onyx on a newer OS or want to use a different interface’s converters. You’d still get the tactile analog mixing experience, but the digital bridge to Pro Tools is handled by newer hardware. According to several professional audio forums I’ve browsed, this hybrid approach is increasingly common for those with legacy FireWire gear.
| Method | Pros | Cons | Verdict |
|---|---|---|---|
| Analog Monitoring via Onyx FireWire | Near-zero latency for tracking, uses mixer’s converters. | Potential driver issues on modern OS, FireWire port dependency. | Great for older systems or if drivers are stable; the intended use for zero-latency monitoring. |
| Analog Monitoring via Onyx Analog Outs to External Interface | Avoids FireWire driver issues, uses preferred interface converters. | Requires an additional audio interface, potentially slightly higher latency depending on the external interface. | Highly recommended if FireWire is unreliable or you want to integrate with a newer USB/Thunderbolt interface. |
Troubleshooting Common Issues
If you’re not hearing anything, or it sounds like a robot gargling marbles, here are a few things to check. First, is the Onyx 1640i even recognized by your computer? Check your system’s FireWire devices. Second, in Pro Tools, under `Setup > Playback Engine`, is the Onyx selected? This is *the* most common mistake. Third, in `Setup > I/O`, are your output paths correctly assigned to the physical channels on the Onyx? Sometimes, simply restarting Pro Tools or your computer after changing settings can fix phantom issues.
Another common problem is the dreaded “clicks and pops.” This usually points to buffer size issues in Pro Tools or a driver problem. For tracking with zero-latency monitoring, you’re generally not relying on Pro Tools’ buffer size for the monitoring signal itself, but it can still affect overall system performance. If you’re getting digital artifacts, try increasing the buffer size in Pro Tools *before* you start recording if you’re not using the direct analog monitoring from the Onyx. However, with proper setup for zero-latency monitoring via the Onyx’s analog path, buffer settings in Pro Tools are less critical for the *monitoring* signal itself.
A less obvious issue I ran into once was a faulty FireWire cable. They look all the same, but some are just better shielded or wired correctly than others. Spending $20 on a new, high-quality FireWire 800 cable solved a persistent, intermittent drop-out problem that had me tearing my hair out for weeks. It looked identical to the cheap one I’d been using, but apparently, it was the digital equivalent of a leaky pipe. (See Also: How To Monitor My Sleep With Apple Watch )
Faq: Your Burning Questions Answered
Can I Use the Onyx 1640i with Logic Pro X?
Absolutely. The principle is the same: set the Onyx 1640i as your audio device in Logic Pro X’s preferences, then configure your output routing to send the signal to the mixer’s analog inputs or digital outputs. The drivers are generally compatible with most major DAWs, though always check Mackie’s website for the latest compatibility notes, especially with newer macOS versions.
Do I Need to Use the Onyx’s Preamps for Monitoring Out of Pro Tools?
Not necessarily for monitoring. You’re using the Onyx primarily as an analog mixer to route the output from Pro Tools to your speakers or headphones. If you’re tracking with the Onyx and want to use its preamps, you’d connect your microphones to the Onyx’s inputs, then route those analog signals back into Pro Tools via a separate audio interface or, if you’re using the Onyx as the main interface, via its own analog inputs mapped in your DAW.
Is Firewire Still a Reliable Connection for Pro Tools?
FireWire is older technology and can be less reliable on modern operating systems compared to USB or Thunderbolt. Driver support can be spotty. Many users opt to use the Onyx 1640i’s analog outputs and route them into a modern USB interface to bypass FireWire entirely, while still retaining the analog mixing console experience. This often provides a more stable connection.
How Do I Get My Guitar Amp Into Pro Tools While Using the Onyx 1640i?
You’d typically mic your guitar amp and send that microphone signal into an input on the Onyx 1640i. Then, from the Onyx, you would route that analog signal back into Pro Tools via its analog inputs, assigning it to an audio track. This allows you to capture the sound of your amp with the Onyx providing the initial gain staging and potentially some analog EQ or processing before it’s recorded digitally.
Why Would I Monitor Out of Pro Tools with Onyx 1640i Instead of Just Using Pro Tools’ Software Monitoring?
The primary reason is latency. Software monitoring within Pro Tools, especially with complex sessions and plugins, introduces a delay between when you play or sing and when you hear yourself. Using the Onyx 1640i for direct analog monitoring bypasses Pro Tools’ processing for the monitoring signal, giving you a near-imperceptible delay, which is essential for accurate tracking performance. It feels much more responsive, like playing an instrument directly.
Verdict
Honestly, getting your Pro Tools session to talk nicely with the Mackie Onyx 1640i for monitoring is less about magic and more about methodical setup. The payoff for figuring out how to monitor out of Pro Tools with Onyx 1640i is that tangible, low-latency control that makes tracking feel like it should. Don’t be afraid to reroute things, check those driver installations twice, and most importantly, trust your ears over what the manual *might* imply.
If you’re still struggling, consider the hybrid approach: use the Onyx for its analog summing and routing, but feed its main outputs into a more modern USB audio interface that has robust driver support. It’s a compromise, but sometimes a necessary one to get things working smoothly without hair-pulling.
The key is patience and understanding that sometimes the simplest settings are the ones that get overlooked. Keep experimenting with those output assignments.
