Is Scarlett 18i20 Balanced Monitor Output? My Real Thoughts.
Struggling with audio gear can feel like wrestling an octopus in a phone booth. You think you’ve got a handle on it, then suddenly you’re tangled in cables and buzzing with confusion. I remember a few years back, staring at my brand new audio interface, utterly perplexed by its back panel. Was I supposed to be using TRS, XLR, or some arcane ritual to get a clean signal to my speakers? Especially when it came to figuring out if the is Scarlett 18i20 balanced monitor output was actually a thing I could rely on without frying my woofers.
So many manuals read like they were written by robots for other robots. They list specs, they boast about features, but they rarely tell you what you *really* need to know when you’re elbow-deep in a project and the clock is ticking. You end up guessing, hoping, and sometimes, just plain messing things up.
Honestly, most of this technical jargon is designed to make you feel stupid or impress you with how clever the engineers are. But for the rest of us, it just causes headaches. Let’s cut through the noise.
Understanding Balanced Connections
Balanced audio connections are, frankly, a lifesaver for anyone serious about getting a clean sound. Imagine trying to carry a whisper across a crowded, noisy room. If you’re just shouting, all that background chatter is going to drown you out. That’s kind of what an unbalanced signal is like when it travels any significant distance or through areas with electrical interference. Balanced connections are like having a noise-canceling microphone system for your audio signal.
The core idea is that the signal is sent down two wires, plus a ground. One wire carries the audio signal, and the other carries an inverted (or ‘out-of-phase’) copy of that same signal. When the signal reaches its destination, the equipment flips that inverted copy back into phase. Any noise that got picked up along the way on *both* wires gets canceled out because one wire’s noise is now inverted relative to the other’s. This is why you’ll often see TRS (Tip-Ring-Sleeve) connectors for balanced audio, as they have the extra contact needed for the second signal wire, unlike TS (Tip-Sleeve) which is typically unbalanced.
I spent around $150 on a set of cheap, unbalanced patch cables when I first set up my studio. For short runs, they seemed fine. But the moment I moved my monitors further away from my desk, a low, insistent hum crept into everything. It was like a tiny, electric mosquito buzzing in my ear, and it drove me absolutely bonkers, especially during quiet passages. Turns out, those fancy gold-plated TS connectors were no match for the power cables running near my speaker stands.
Scarlett 18i20: Balanced Outputs Explained
So, to directly address the question: is Scarlett 18i20 balanced monitor output a real thing? Yes, it absolutely is. The Focusrite Scarlett 18i20, in its various generations, is designed with professional audio in mind, and that means providing balanced outputs for your main studio monitors. You’ll typically find these on the rear panel, usually labeled ‘Monitor Outputs’ or ‘Line Outputs,’ and they use the TRS connector type. This is fantastic news because it means you can run longer cables from your interface to your speakers without picking up as much unwanted noise and interference. This is a significant upgrade from interfaces that only offer unbalanced RCA or TS outputs, which are more prone to sonic degradation over distance. (See Also: What Frequency Should My Monitor Be )
When I was looking at interfaces years ago, some cheaper options would tout ‘line outputs’ but wouldn’t specify balanced or unbalanced. It felt like a gamble. You’d buy it, hook it up, and pray you wouldn’t get that dreaded 60Hz hum. Having dedicated, balanced monitor outputs on an interface like the 18i20 is a huge selling point for serious home studio users and professionals alike. It shows Focusrite understands that clean signal path from the get-go is paramount.
What Cables to Use?
This is where the confusion really starts for a lot of people. If the Scarlett 18i20 has balanced monitor outputs, what kind of cables do you need? You need TRS to TRS balanced audio cables. These cables have a TRS connector on both ends. The ‘S’ in TRS stands for Sleeve, and it’s the third contact point on the plug, carrying that second, inverted audio signal. Do NOT use TS cables (which only have two contact points: Tip and Sleeve) for your main monitor connections if you want to take advantage of the balanced outputs. Using a TS cable in a TRS balanced jack will effectively short out the ring connection, which can sometimes cause issues or, at best, render the balanced connection useless and revert to an unbalanced signal, making it susceptible to noise. It’s like trying to wear a suit with one sleeve cut off – it’s not going to work as intended.
I once saw a buddy try to connect his expensive studio monitors to his interface using a bunch of guitar cables (TS). He complained about his mixes sounding thin and noisy. It took me ten minutes to point out he was basically undoing all the good design work of his interface and speakers. The visual cue is important: look for the three black rings on the metal plug if you’re unsure. A TS cable will only have two.
Connecting Your Speakers
Connecting your studio monitors is pretty straightforward once you’ve got the right cables. Take your TRS to TRS cables and plug one end into the ‘Monitor Outputs’ on the back of your Scarlett 18i20. Make sure you’re using the correct pair – the 18i20 typically has dedicated main monitor outputs separate from its line outputs, though both are balanced.
Then, connect the other ends of the cables to the inputs on your studio monitors. Most active studio monitors will have either XLR or TRS inputs. If your monitors have XLR inputs, you’ll need TRS to XLR cables. Again, the TRS end connects to the interface, and the XLR end connects to the monitor. If your monitors have TRS inputs, then TRS to TRS cables are your ticket. Always double-check your monitor’s input types. It’s not uncommon to have a mix of inputs on a single piece of gear, but for the Scarlett 18i20’s balanced monitor outputs, you’ll be pairing them with either TRS or XLR on the speaker side.
Before you power everything up, it’s a good practice to turn the volume knobs on your active monitors all the way down. Then, power on your monitors first, and *then* power on your Scarlett 18i20. To turn off, power down the interface first, then the monitors. This sequence helps prevent loud pops and thumps that can damage your speakers or your hearing. Trust me, I’ve had a few ‘startling’ moments early on that made me learn this lesson the hard way. That sudden ‘thwack’ can really wake you up, but not in a good way.

When Balanced Might Not Be Enough
While balanced connections are a massive improvement, they aren’t a magic bullet for every audio problem. If you’re running cables through a space with extremely high levels of electromagnetic interference (EMI) – like right next to a massive industrial transformer or a poorly shielded dimmer switch circuit – you might still pick up some noise. This is where things like high-quality, shielded cables become even more important. Think of it like this: a balanced connection is a great suit of armor against everyday street thugs (ambient noise), but if you’re facing a dragon (extreme EMI), you might need a full suit of enchanted plate mail.
Another factor is the quality of the interface and monitor circuitry itself. A poorly designed balanced output or input can still introduce noise or distortion. The Scarlett 18i20, being a professional-grade interface, generally has good quality components. However, always listen critically. If you’re hearing unusual artifacts even with balanced connections, it’s worth troubleshooting your entire signal chain, from source to speakers.
I’ve seen setups where people spent a fortune on cables and interfaces but ran them through a spaghetti junction of power cords and dirty power. It’s a bit like buying a Ferrari engine but then feeding it cheap, contaminated fuel. You’re not going to get peak performance, and you risk damaging the engine. The entire ecosystem matters. Electrical grounding can also be a sneaky culprit. Improper grounding is a common cause of hums and buzzes that even balanced audio can’t fully eliminate. Sometimes, a simple, high-quality power conditioner can make a world of difference, often overlooked in favor of more glamorous gear purchases.
Technical Specifications and Common Issues
Focusrite generally lists the Scarlett 18i20’s monitor outputs as balanced TRS, operating at line level. This means they are designed to send a strong, clean signal to powered monitors or the line inputs of amplifiers. The impedance is typically low, which is good for maintaining signal integrity. Impedance matching is one of those technical terms that sounds scary, but essentially, when impedances are well-matched between the source and the destination, you get the most efficient transfer of the audio signal without loss or unwanted coloration.
A common issue people encounter is accidentally selecting the wrong output in their software. Many DAWs (Digital Audio Workstations) and operating systems allow you to select which outputs you want to use for monitoring. Ensure that your Scarlett 18i20’s main monitor outputs are selected as your primary playback device in your audio settings and within your DAW. Sometimes, you might have configured other line outputs for other purposes, and if your DAW is set to send audio to those instead, you won’t hear anything from your main monitors, or you might hear something unexpected.
Is Scarlett 18i20 Balanced Monitor Output Safe for Headphones?
No, the monitor outputs are designed for line-level signals going to powered speakers. Headphones typically require a dedicated headphone amplifier, which is why audio interfaces have a separate, often lower-impedance, headphone jack designed to drive headphones effectively. Plugging headphones directly into the monitor outputs is not recommended; you’ll likely get a very low volume and potentially damage the headphones or the interface’s output circuitry.

What Is the Difference Between Balanced and Unbalanced Audio?
Balanced audio uses three conductors (two signal wires plus a shield) to transmit audio, allowing for noise cancellation by inverting and re-combining the signal. Unbalanced audio uses only two conductors (one signal wire plus a shield) and is more susceptible to picking up noise and interference over longer cable runs.
Can I Use Ts Cables for Balanced Outputs?
You can physically plug a TS (unbalanced) cable into a TRS (balanced) jack, but it will only use the tip and sleeve connections, essentially making it an unbalanced connection. This defeats the purpose of the balanced output and leaves your signal vulnerable to noise over distance. For optimal performance, always use TRS to TRS or TRS to XLR cables for balanced connections.
A Practical Comparison Table
| Feature | Scarlett 18i20 Balanced Monitor Outputs | Typical Unbalanced Outputs (RCA/TS) | My Verdict |
|---|---|---|---|
| Connection Type | TRS (Tip-Ring-Sleeve) | RCA or TS (Tip-Sleeve) | TRS is the professional standard for a reason. |
| Noise Rejection | High (due to balanced design) | Low (susceptible to interference) | This is the biggest practical advantage. No more buzzing! |
| Cable Length Capability | Good for longer runs (up to 30ft+ with quality cables) | Poor, prone to noise over 10-15ft | Essential for setups where monitors aren’t right next to the interface. |
| Signal Integrity | Maintained better over distance | Degrades more easily | Clearer highs and lows, less coloration. |
| Common Use Case | Studio monitors, professional audio gear | Consumer electronics, turntables (sometimes), guitar pedals | Don’t mix them up for critical listening. |
The Scarlett 18i20’s balanced monitor output is a cornerstone feature that elevates it beyond entry-level gear. It’s not just a spec sheet item; it’s a practical element that directly impacts the quality and reliability of your sound. I’ve seen too many people get bogged down by the basics, only to wonder why their mixes don’t translate or why their studio has an annoying background hum. Getting the connection right from the interface to the speakers is step one.
Final Thoughts
Honestly, the fact that the Scarlett 18i20 has balanced monitor outputs is probably one of the most significant reasons someone serious about audio would choose it over a cheaper, less capable interface. It’s not the flashiest feature, but it’s one of the most fundamentally important for maintaining a clean and reliable audio path. If you’re looking at an interface and it doesn’t have balanced monitor outputs, I’d seriously question if it’s built for anything beyond casual listening or very short cable runs.
So, to circle back, the is Scarlett 18i20 balanced monitor output is a definite yes, and it’s a really good thing to have. This isn’t some marketing fluff; it’s a practical aspect of the hardware that directly affects the quality of your sound and the reliability of your setup. Using the correct TRS or XLR cables to connect to your monitors is non-negotiable if you want to avoid headaches and get the best possible sound quality.
Don’t fall into the trap of thinking that all audio cables are created equal. The cheap ones might seem fine initially, but they’ll bite you later, especially with noise. Spend a little extra on decent, balanced cables – your ears will thank you, and more importantly, your mixes will sound better because you’ll be hearing an accurate representation of what’s going on.
If you’re still wrestling with hums or buzzes after confirming your cables and connections, take a step back and look at your power situation and the overall shielding in your room. Sometimes the solution isn’t more expensive gear, but a smarter approach to how everything is wired and grounded.
