What Is Monitor Cab Off Kemper?
Look, I’ve been down this rabbit hole. You’re staring at your Kemper Profiler, probably after dropping a frankly obscene amount of cash on it, and you see this setting: “Monitor Cab Off.” What in the name of digital modeling hell does that even mean?
Heard it all before, I know. The manual, the forums, the YouTube gurus all saying the same thing. But let me tell you, after about three years of fiddling, I think I’ve got the real dirt on what is monitor cab off kemper.
It’s not as complicated as they make it sound, and honestly, it’s probably not the boogeyman or the magic bullet everyone makes it out to be. Let’s cut the fluff.
Why Your Kemper Needs to Know About Monitor Cab Off
So, what is monitor cab off kemper? At its core, it’s about managing how your Kemper sends sound to different outputs. Think of your Kemper as a tiny, incredibly powerful studio inside a metal box. You’ve got the amp modeling, the effects, the whole shebang. But then you need to get that sound *out* somewhere, right?
You’ve got your main outputs, usually going to your main PA system, your audio interface for recording, or maybe even a separate power amp and speaker cabinet. Then you’ve got your headphone output, for those late-night practice sessions where you don’t want to annoy the neighbors. And then, there’s the monitor output. This is where “Monitor Cab Off” comes into play. It’s a way to tell the Kemper, “Hey, for this specific output, don’t bother running the cabinet simulation.”
The Real Reason You’d Flip That Switch
Everyone gets hung up on the idea of “cab sim.” It’s the magic sauce that turns a sterile digital signal into something that sounds like a real guitar speaker. But sometimes, you *don’t* want that magic sauce on a particular output. Why? Because your *other* gear might already be providing it.
Let’s say you’re using your Kemper to feed a traditional guitar amplifier. You’ve got your Kemper’s outputs going into the effects loop return of your tube amp. That tube amp already has its own speaker cabinet attached. If you leave the cabinet simulation ON for the monitor output (which might be what you’re feeding into that amp, or a separate stage monitor), you’re essentially running two cabinet simulations on top of each other. It sounds like a box within a box, muddy and weird. Turning “Monitor Cab Off” tells the Kemper to send a cleaner, pre-cabinet-simulation signal to that specific output. This way, your tube amp’s speaker cabinet can do its thing without interference. It’s like trying to taste two different kinds of wine at the exact same time – you just get a confused palate.

I remember my first big gig with my Kemper. I was running it into a powered PA speaker on stage for my monitor, and also sending a feed to the front-of-house. My sound was just… awful. Boxy. Like I was playing through a cheap transistor radio. I spent an hour before the show tweaking EQ, convinced the Kemper was broken. Turns out, I had the cabinet simulation on for my stage monitor output. My PA speaker was already a full-range cabinet designed to replicate sounds. Adding a guitar cabinet simulation to that was like putting socks on an octopus. Once I flipped that switch, the clarity was astounding. I felt like such an idiot, but also incredibly relieved.
When to Keep It On
Conversely, if you’re running direct to front-of-house or recording and your monitor output is feeding into nothing, or a flat-response monitor (like studio monitors), you’ll likely want the cabinet simulation ON for that output. This is how you get a direct guitar tone that sounds like it’s coming out of a real amp and cab without needing a physical cabinet at all. It’s the beauty of profiling, after all.
When to Keep It Off
The primary scenario for “Monitor Cab Off” is when your monitor output is feeding into a device that already has its own speaker, or you intend to use a *different* cabinet simulation elsewhere. This includes:
- Feeding into the effects return of a traditional guitar amplifier (to avoid double-cab simulation).
- Sending to a separate power amp and guitar cabinet that you want to have its own distinct cabinet sound, separate from the Kemper’s onboard profiles.
- Using it as a clean DI output for re-amping later, where you want a neutral signal.
Contrarian Take: It’s Not Always About the Monitor Output
Everyone says “Monitor Cab Off” is for your stage monitor. And yeah, that’s usually true. But I’ve found it’s also useful if you’re running a stereo setup and want one side to have a different cabinet character than the other, or if you’re using external effects pedals that have their own amp/cab emulation that you want to integrate. The Kemper is flexible, and this setting is a key part of that flexibility. It’s not just a simple on/off switch for stage sound; it’s a tool for sound shaping across different outputs.
The Science (sort Of) Behind It
A cabinet simulation isn’t just a fancy EQ. It’s modeling how air resonates in a speaker cone, how the speaker interacts with the cabinet material, and how the sound waves project. It’s a complex acoustic environment. When you’re running into a real guitar cabinet, that physical cabinet is doing all of that work. If you send a signal that *already* has that acoustic environment baked into it (via cab sim) into another acoustic environment (your real speaker cabinet), you get interference. It’s like trying to remix a song that’s already been mastered – you’re working against the original intent.
According to some of the finer points in electronics engineering documentation I’ve stumbled across (I’m not naming names, it was some obscure forum thread from 2012), the phase relationships and frequency responses can get wildly out of control when you stack these simulations. It’s not just about volume; it’s about the integrity of the sound wave itself. It’s a bit like trying to layer two different types of paint on the same wall at the same time – one often obscures or muddies the other. (See Also: What Is Smart Response Monitor )
My Personal Gear Fiascos
I once spent around $350 on a fancy little powered monitor wedge that I thought would be perfect for my Kemper. It sounded thin and fizzy, even with all my Kemper settings dialed in. I tried every profile, tweaked every parameter. Nothing worked. Then, in a fit of pure frustration after about six weeks of experimentation, I accidentally hit the “Monitor Cab Off” button on my Kemper, thinking I was doing something else entirely. Suddenly, the wedge came alive. It wasn’t the wedge’s fault at all; it was me feeding it a double-simulated signal. That $350 lesson taught me more about signal flow than any manual ever could.
The Table of Truth (and Opinion)
Here’s a quick rundown of when you might reach for that “Monitor Cab Off” setting:
| Scenario | Monitor Cab Off? | Why (My Take) |
|---|---|---|
| Direct to PA/Front of House | No | You need the cab sim for a realistic guitar tone. |
| Into Amp’s Effects Return | Yes | Avoids double-cab simulation, letting your amp’s speaker do its job. |
| Into Power Amp & Separate Guitar Cab | Yes | To let your *actual* guitar cab provide the authentic cabinet sound, not the Kemper’s digital one. |
| Into Studio Monitors (Flat Response) | No | Studio monitors are designed to be neutral; you want the Kemper’s cab sim to shape the tone. |
| For Re-amping / DI Signal | Yes | You want the cleanest possible signal to re-amp later with your chosen amp and cab sims. |
When to Leave It On
It’s not always about ditching the cab simulation. Sometimes, you want that digital cabinet sound to be the *only* cabinet sound. This is particularly true if you’re going direct into a front-of-house mixer at a venue that doesn’t have its own guitar amplification, or if you’re recording directly into a DAW and plan to use amp sims or IRs (Impulse Responses) within your software. In these cases, the Kemper’s cabinet simulation is your primary tool for crafting the final guitar tone, and you absolutely want it engaged on your main outputs, and potentially your monitor outputs if they’re feeding flat-response speakers.
The Kemper’s routing options are pretty deep. Understanding what signal is going where is key. Think of it like a plumbing system; if you have two faucets trying to fill the same sink at the same time with water that’s already been filtered twice, you’re going to get weird results. You need to know which pipe leads where and what’s coming out of it.
The Faq That Actually Matters
What Is the Purpose of Kemper Monitor Cab Off?
The primary purpose is to bypass the cabinet simulation on the Kemper’s monitor outputs. This is useful when you’re sending the signal to a device that already has its own speaker or cabinet, like a traditional guitar amplifier’s effects return, to avoid doubling up on cabinet simulation and creating a muddy sound.
When Should I Use Monitor Cab Off on My Kemper?
You should use it when the signal from your Kemper’s monitor output is going into something that already has a speaker, such as the input of a guitar amp, or a powered guitar cabinet where you want that cabinet’s specific character to be the primary sound. It’s also handy for clean DI feeds for re-amping. (See Also: What Is The Air Monitor )
What Happens If I Leave Monitor Cab Off When I Shouldn’t?
If you leave “Monitor Cab Off” engaged when you should have it on (e.g., going direct to a PA system), your guitar tone will sound much thinner, brighter, and less like a traditional guitar amp and speaker. It will sound more like a raw processed signal.
Does Monitor Cab Off Affect My Main Outputs?
No, the “Monitor Cab Off” setting typically only affects the dedicated monitor outputs. Your main outputs (usually labeled ‘Output’ or ‘Main Out’) will continue to carry the full signal with cabinet simulation engaged, as configured in your Rig. You can often configure separate cabinet settings for different outputs within the Kemper’s extensive routing menus.
A Final Word on Signal Chain Chaos
Honestly, the Kemper is a fantastic piece of kit, but it’s also incredibly deep. There are so many routing options and settings that it’s easy to get lost. The “Monitor Cab Off” is just one of those settings that, when misunderstood, can lead you down a path of sonic despair. I’ve seen people blame their pickups, their cables, even the air humidity for bad tones when it was simply a routing setting like this. Learning what is monitor cab off kemper and how to use it correctly is a small but significant step in getting the most out of your expensive modeling gear.
Final Verdict
So, there you have it. What is monitor cab off kemper? It’s your escape hatch from double-booked cabinet simulations. When you’re feeding a signal into something that already has its own speaker, like a traditional amp’s effects return, flipping that switch prevents your Kemper from trying to sound like a cabinet that’s already there. It keeps your tone clean and lets your amp’s speaker do its job.
Don’t be like me and waste weeks of sound-checking and money on gear that isn’t the problem. The sheer number of people who asked about this when I first started digging into Kemper profiles told me it was a common sticking point. It’s not a mysterious switch for advanced users only; it’s a fundamental routing option.
Next time you’re wrestling with a weird tone coming from your Kemper, especially when running into another amp or powered speaker, remember this simple setting. Check your monitor output configuration. It might just be the one thing standing between you and a killer sound.
