A Portable Amp at the Heart of a Creative Setup

The K.O.-AMP combines the functions of an amplifier, portable speaker and mixing hub. Its appeal is simple: it brings together the elements of a musical session without multiplying the number of devices. A guitar, a voice, a stereo line source or a computer can all be connected to the same system, designed to support both playing and creativity.

Its compatibility with the ep-plug and ep-grid ecosystem extends this concept. With the optional K.O. DOCK KIT, EP series machines can be attached to create a compact setup. The amp then becomes the meeting point between instruments, machines and audio sources.

For Musicians Who Play Beyond the Studio

The K.O.-AMP is designed for guitarists, singers and creators who want a portable setup for working, rehearsing or improvising. A solo musician can combine their instrument with accompaniment; a duo can bring together guitar and vocals; and machine enthusiasts can connect a drum machine and share their session.

This versatility suits amplified acoustic compositions, pop, electronic improvisation and work on backing tracks. At home, outdoors or during an impromptu performance, the built-in battery means you do not have to rely on a mains outlet. The handle and 3.20 kg weight make it easy to move between sessions.

Six Sources, Effects and Multiple Ways to Share Your Sound

Simultaneous mixing of six sources lets you build a setup around your needs. The instrument input on a 6.35mm jack offers low- or high-gain selection. The XLR microphone input features 48 V phantom power for microphones that require it, while the stereo line input accommodates a suitable audio source.

The eight guitar and microphone effects presets let you shape sounds directly, without necessarily adding a pedalboard or processor. To keep your hands on the instrument, the optional K.O.-PEDAL controller provides foot controls as well as additional looping functions.

The USB 2.0 audio interface allows you to integrate the K.O.-AMP into a computer-based setup, while the stereo line output provides a connection to an external system. On the wireless side, Bluetooth with LE Audio supports your compatible sources. Bluetooth Broadcast mode lets you transmit to multiple compatible K.O.-AMP units, spreading the sound across a larger space.

An Open Approach to Guitar, Vocals and Machines

The K.O.-AMP focuses on source versatility rather than limiting its use to guitar. You can combine an instrumental part, vocals and accompaniment, then use the presets to give the guitar and microphone sounds a different color. This approach encourages you to seek an overall balance, from a sung song to a session built around a drum machine.

The instrument input's gain selection helps adapt the input to the signal being used. The built-in effects then provide a direct way to explore different textures, while the connectivity lets you keep the same point of diffusion when moving from individual work to a shared session.
