Teenage Engineering's New DJ Mixer Does Way More Than Just Mixing
Teenage Engineering, a company known for making creative music equipment, has released a new device called the EP-136 KO Sidekick. It's a small, portable mixer that also works as a recording interface for a computer and lets you control music software — all in one palm-sized box measuring about 9 inches long.
This is the company's second major product in its EP line. The first, the EP-133 KO II, came out in late 2023 and was based on one of Teenage Engineering's popular pocket-sized samplers. The pattern is clear: when they find something people like, they build bigger, more powerful versions.
What's Inside and How It Connects
The EP-136 has two main inputs where you can plug in headphone-jack connections from other devices, plus an extra input for something like a microphone or second source. Sound comes out through main and cue (headphone) outputs, also using standard headphone jacks.
Each input has its own compressor, a tool that keeps volume levels steady, and you can choose from three different EQ settings to shape how the audio sounds. The device runs on two AA batteries for portable use or plugs into power via USB-C. When you connect it to a computer via USB, it becomes an 8-input, 4-output audio interface — think of it as a translator that sends sound in and out between your hardware and your computer.
The screen is a small color display that shows you what's happening as you work. You can also chain multiple EP-136 units together if you need more mixing channels.
Performance Tools Built In
The mixer includes six performance effects — the company calls them "knock-out" effects — plus additional effects that respond to how you tilt or move the device. There's also a built-in sequencer, which is essentially a tool for programming and repeating patterns, and a looper that remembers what you played over two beats and can manipulate effects automatically while it plays.
These features mean the EP-136 isn't just for mixing recorded music like a traditional DJ mixer. You can also use it to create and perform new music on the fly.
Using It With Your Computer
When you plug the EP-136 into a computer via USB, it works as both an audio interface and a MIDI controller. MIDI is a standard language that lets hardware devices and software talk to each other. This means you can route audio through it and also use its buttons and knobs to control music-making software on your screen.
The bigger picture here is that music production equipment keeps getting more compact and multi-purpose. Thirty years ago, to do what the EP-136 does, you would have needed four or five separate pieces of gear, each with its own cables and power supply. The fact that companies can now pack that functionality into something that fits in a backpack shows how far the technology has come.
Warranty and Support
Teenage Engineering backs the EP-136 with a 12-month warranty for defects. The device is made and shipped through the same networks the company uses for its other products.
What This Means for Musicians and Producers
The EP-136 tries to solve a real problem: people who make electronic music want equipment that's small enough to take anywhere but powerful enough not to compromise what they can do. The mixer works whether you're traveling, working from home, or setting up in a studio. It blends DJ tools with production tools, because those lines have blurred in modern music.
The real test will be whether the individual parts — the audio quality, the effects, the mixing tools — are genuinely good enough compared to specialized devices that do only one job. And whether the company can keep the loyal fans who loved it as a design object while also attracting people who just need it to work well.
The EP-136 shows Teenage Engineering is aiming to be taken seriously alongside mainstream mixer and interface brands, not just as a stylish alternative. The specifications suggest that ambition is genuine.
