teenage engineering EP-136 K.O. sidekick 2-Channel Stereo DJ Mixer, Audio Interface and FX Processor

Compact mixing, performance effects and digital recording converge in the teenage engineering EP-136 K.O. sidekick, a portable DJ mixer, audio interface and FX processor designed for modern beatmakers and hybrid setups. Built around two stereo channel strips with an additional stereo aux input, the sidekick expands your routing with flexible three-source mixing, while onboard EQ, compression and beat matching provide hands-on control for shaping your sound in real time. Additionally, a built-in USB audio interface supports multichannel recording and playback, making it easy to capture sessions directly into a DAW or integrate with a computer-based workflow. With dual FX blocks, a pressure-sensitive FX pad and a high-resolution LCD screen, the sidekick blends tactile performance control with compact portability, making it a powerful tool for studio production, home listening setups and live performance environments.

Flexible Multi-Source Mixing With Dedicated Channel Control

At its core, the sidekick functions as a compact stereo mixer with two primary channel strips and a third aux input, allowing you to combine multiple sources such as samplers, mobile devices or external instruments. Each channel features dedicated gain, EQ and compression controls, giving you immediate access to shaping dynamics and tonal balance without menu diving. The inclusion of configurable EQ styles—DJ, studio and parametric—adds further flexibility, letting you tailor the response to different workflows. Whether blending tracks, cueing transitions or managing multiple inputs in a compact setup, the mixer layout provides a clear and responsive control surface.

Integrated USB Audio Interface for Recording and Playback

Beyond mixing, the sidekick doubles as a USB audio interface, supporting multichannel recording and playback for streamlined integration with digital audio workstations. With four stereo record channels capturing inputs and main output, you can track performances, external gear or full mixes directly into your DAW. A dedicated stereo playback channel allows audio from a computer or phone to be routed back into the mixer, making it easy to incorporate backing tracks or reference material. High-quality 48kHz/24-bit AD/DA conversion ensures clean signal capture, supporting both studio recording and portable production workflows.

Dual FX Engines With Expressive Performance Controls

Creative control is central to the sidekick’s design, with dual FX blocks offering a range of performance-ready effects including delay, tape-style processing, looping, tremolo, filtering and more. The pressure-sensitive FX pad and high-resolution FX bender provide tactile, real-time manipulation, allowing you to shape effects dynamically during playback or performance. Additional tools such as beat matching per channel and the tap-FX sequencer enable rhythmic precision and creative layering, making it easy to build transitions, textures and movement into your mix without external processors.

Portable Design With Expandable EP-Series Integration

Designed for portability and modular use, the sidekick runs on two AAA batteries or USB-C power, making it suitable for mobile setups, desktop use or live performance environments. Its compact form factor aligns with the EP-series ecosystem, allowing it to physically connect with compatible units using standard LEGO-style pins for expanded setups. A dedicated cue output enables headphone monitoring or use as an external effects loop, while the main output connects directly to monitors or a PA system. The lightweight design and integrated display make it easy to transport, set up and operate across a wide range of environments.

Mixing and Effects Hub for Modern Creators

Combining flexible mixing, integrated recording, expressive effects and portable design, this unit bridges the gap between studio tool and live performance device. Its intuitive control layout, multichannel USB interface and performance-focused FX make it well suited for beatmakers, DJs and musicians working across hybrid setups. Whether capturing ideas in the studio, managing playback at home or performing live with multiple devices, the teenage engineering EP-136 K.O. sidekick provides a streamlined, all-in-one solution for shaping and controlling your sound.
