How to Monitor Behringer 1240usb: My Mistakes
Honestly, when I first got my hands on the Behringer Xenyx 1240USB, I thought I’d cracked the code for simple live sound monitoring. Turns out, my initial setup was about as effective as using a sieve to bail out a sinking boat. It took me weeks of fiddling, re-reading dense manuals, and a fair bit of colorful language before I figured out the nuances of how to monitor Behringer 1240USB.
You’d think it’s straightforward, right? Plug in, turn knobs, hear sound. But the devil, as always, is in the details, especially when you’re trying to get clean monitor mixes for a band or even just for yourself during recording.
The marketing hype around these mixers often glosses over the practical realities of getting a usable, latency-free monitor feed. I wasted about $150 on overpriced, supposedly ‘studio-grade’ headphone amps that did precisely nothing to improve my situation with this board, which was frankly infuriating.
So, let’s cut through the noise and talk about what actually works for monitoring on the 1240USB.
Getting Your Main Mix Right First
Look, before you even think about monitor mixes, your main stereo output needs to be dialed in. If your master fader is cranked into the red, or your EQ is making everything sound like a tin can gargling gravel, your monitor mix is going to sound just as bad, if not worse. I learned this the hard way at a small gig when the lead singer complained his monitor sounded muddy. Turns out, the main mix was equally muddy, and he was just hearing the ‘best of a bad bunch’ that was coming through his wedge.
Spend time with your mains. Get a clear, balanced sound. Then, and only then, should you even glance at the aux sends for your monitoring needs. It’s like building a house; you wouldn’t start painting the walls before the foundation is poured, would you?
Understanding Aux Sends: Your Monitor Lifeline
The core of how to monitor Behringer 1240USB lies in its auxiliary sends. This mixer has multiple aux sends, which is great, but you need to know which one to use for your monitor. Most of the time, you’ll be using the ‘FX’ or ‘MON’ aux sends, depending on how Behringer has labeled them or how you’ve configured them. For a dedicated monitor mix, I almost always use the ‘MON’ send, usually labeled ‘Aux 1’ or ‘Aux 2’ on the channel strips. This is where you’ll build your dedicated signal path for the performers.
These sends are typically post-fader by default, meaning whatever you do to the channel’s main fader affects the monitor mix too. If you need a pre-fader monitor mix – where the channel fader *doesn’t* affect the monitor send – you’ll need to check the small buttons next to the aux knobs on each channel. I often forget to flip that pre-fader switch when setting up a new band, and then I get calls about the singer’s monitor suddenly becoming deafeningly loud when they hit their big chorus. Seven out of ten times, it’s that simple post-fader setting. (See Also: How Lcd Monitor Works Animation )
You’ll want to set these sends for each instrument or vocal you want in the monitor mix. Remember, what you hear in your headphones from the main stereo out is NOT what your performers are hearing in their monitors. You have to actively build their mix using those aux sends.
When you’re routing, imagine a pipe from each channel strip’s aux send knob directly to your monitor output. You turn that knob up, more of that channel’s signal goes into the monitor mix. Simple, but incredibly effective when done right. The tactile feel of those plastic knobs, clicking into place as you adjust, is a familiar sensation to anyone who’s spent hours behind a board.
Setting Up the Monitor Output & Headphone Amp
Now that you’re sending signals to your monitor outputs (usually on the back of the mixer, often labeled ‘MONITOR OUT’ or ‘PHONES’), you need something to actually amplify them. If you’re using powered monitor wedges, they plug directly into these outputs. If you’re using passive wedges, you’ll need a separate power amplifier. For headphone monitoring, especially during practice or recording, you’ll want a dedicated headphone amplifier.
The 1240USB has a headphone output, but it’s often not powerful enough for multiple performers or for loud stage monitoring. That’s where external headphone amps come in. I’ve found that a simple 4- or 8-channel headphone distribution amplifier works wonders. You send your main stereo output *or* a specific aux mix to this amp, and then each performer gets their own volume control. This avoids the endless ‘more me!’ arguments.
Initially, I tried daisy-chaining cheap headphone splitters, which was a disaster. Sound quality degraded rapidly, and the volume was inconsistent. It sounded like I was trying to listen to music through a tin can tied to a string – utterly useless for critical listening.
My Setup Recommendation:
| Component | Function | My Verdict |
|---|---|---|
| Behringer 1240USB | Mixer/Interface | Gets the job done for basic to intermediate setups. |
| Dedicated Headphone Amp (e.g., Behringer HA8000) | Provides multiple headphone outs with individual volume control. | Absolutely necessary for anything beyond a solo performer. Makes everyone happy. |
| Powered Monitor Wedges | Stage speakers for performers. | Convenient, but can be bulky. Ensure they have enough power. |
| Active DI Boxes | For instruments needing a balanced signal to the mixer (e.g., acoustic guitars, keyboards). | If you’re getting hum or buzz, a good DI box is your best friend. |
Common Pitfalls and How to Avoid Them
One of the biggest mistakes I see people make when trying to figure out how to monitor Behringer 1240USB is forgetting about latency. Latency is that annoying delay between when a musician plays a note and when they hear it through their monitor. While the 1240USB is primarily an analog mixer with a USB interface, the USB connection *can* introduce latency if you’re not careful with your computer’s audio settings. (See Also: How To Attach An Additional Monitor )
For live monitoring, you generally want to bypass the computer entirely and use the mixer’s direct analog outputs for your monitors. If you *are* using the USB for playback or recording and want to monitor that along with live inputs, you need to configure your audio interface or DAW settings correctly. Setting your buffer size too high on your computer is a sure-fire way to introduce noticeable lag. I spent nearly an hour once trying to figure out why the drummer sounded like he was playing along to a bad echo, only to realize my DAW buffer was set to 1024 samples. Dropping it to 128 samples fixed it instantly.
Another common issue is feedback. That piercing squeal that makes everyone cover their ears? It happens when a microphone picks up sound from a speaker, which then gets amplified by the speaker, which is then picked up by the microphone again, creating a loop. To combat this, keep monitor speakers pointed away from microphones, use EQ to cut offending frequencies (there are dedicated feedback suppressor plugins or hardware units for this, but a graphic EQ is often enough), and don’t push monitor levels higher than necessary.
The visual cues on the Behringer 1240USB are helpful, too. Pay attention to the meters. If a channel’s signal is constantly hitting the red on the monitor send, you’re asking for trouble – either clipping or feedback. A little headroom goes a long way. It’s the subtle flicker of the LEDs just before they turn red that tells you you’re close to the edge, a visual warning that’s as good as any spoken caution.
People Also Ask:
How Do I Connect My Behringer 1240usb to My Monitors?
You’ll typically use the ‘MONITOR OUT’ or ‘PHONES’ jacks on the back of the mixer to connect to your powered monitor speakers or a separate headphone amplifier. If you’re using passive monitors, you’ll need to connect the ‘MONITOR OUT’ to the input of a power amplifier first, and then connect the amplifier’s output to your passive speakers. Always check your mixer’s manual for the specific labeling of these outputs.
Can I Use the Behringer 1240usb for Live Gigs?
Yes, absolutely. The 1240USB is designed for live sound reinforcement and can handle moderate-sized gigs. You’ll need to connect microphones and instruments to the input channels, use the aux sends for monitor mixes, and connect the main outputs to your PA system or powered monitors. Its built-in USB interface is also useful for playback or recording.
What Is the Difference Between Fx and Mon Sends on a Mixer?
Generally, ‘FX’ sends are intended for adding effects like reverb or delay to your main mix or monitor mixes, often with an associated effects processor on the mixer itself. ‘MON’ (monitor) sends are specifically designed for creating independent monitor mixes for performers on stage. While you *can* use an FX send for a monitor, it’s usually better to use a dedicated MON send to keep your effects and monitor mixes separate and controllable.

How Do I Get a Separate Mix for My Headphones and Main Speakers?
To get a separate mix for headphones and main speakers, you’ll need to use the auxiliary sends. Route your desired instrument and vocal signals to one of the aux sends (e.g., Aux 1), turn up the knob for that send on each channel you want in the mix, and then send that Aux 1 output to your headphone amplifier. Your main stereo outputs will carry your main PA mix, which can be different from the headphone mix.
The USB Interface: Recording vs. Monitoring
The Behringer 1240USB has a USB interface, which is a huge selling point. However, this can be a double-edged sword when it comes to monitoring. When you’re recording, you might want to hear your recorded tracks along with the live input from microphones. The trick is to configure your DAW (Digital Audio Workstation) correctly.
Most DAWs have settings for input monitoring and playback monitoring. If you’re using the USB connection to send audio to your computer for recording, you’ll typically select the 1240USB as your audio interface. Then, in your DAW’s preferences, you’ll set up its output routing. You can often choose to send the main stereo mix from the mixer back into your computer’s audio interface for monitoring, or you can use the mixer’s direct aux sends. For the lowest latency when tracking, it’s often best to monitor through the mixer’s analog aux sends directly, bypassing the computer’s processing as much as possible for the live input signal.
I spent a solid afternoon wrestling with my DAW trying to get a clean, zero-latency mix for a vocalist. The digital bleed was awful. Turns out, I had accidentally enabled software monitoring in my DAW *and* was also monitoring through the mixer’s aux send. Turning off the software monitoring in the DAW was the key. It felt like discovering a secret shortcut after wandering through a maze for hours.
Think of the USB connection as a separate pathway. It’s like having a different road to the same destination. You can either drive directly on the analog highway (using aux sends for monitors) or take the digital scenic route (USB to computer, then back to the mixer). For critical live monitoring, the analog highway is almost always faster and smoother.
Final Verdict
Figuring out how to monitor Behringer 1240USB effectively comes down to understanding those aux sends and how they feed your output devices. Don’t get bogged down in trying to make the USB connection your primary monitoring path for live sound; it’s usually a recipe for latency headaches.
Focus on building clean, separate mixes for each performer using the dedicated monitor outputs or a good headphone amplifier. And for goodness sake, get your main stereo mix sorted *before* you even touch the monitor knobs. It’s a simple step that most people overlook, leading to a cascade of sonic problems.
My initial attempts cost me time and money because I didn’t respect the basic signal flow. Treat the monitor mix as a distinct entity, not an afterthought. Your performers will thank you, and your ears will too.
So, before your next gig or recording session, take a moment to trace those aux send signal paths on your 1240USB. You might be surprised at what you find, and more importantly, at how much better your monitoring sounds.
