Teenage Engineering EP-35 K.O.-AMP: connect your instruments and take your session anywhere

The Teenage Engineering EP-35 K.O.-AMP is a battery-powered portable instrument amplifier with a USB-C audio interface, designed for recording, monitoring, and improvisation sessions. It supports microphones, electric guitars, basses, synthesizers, drum machines, and other line-level sources, with simultaneous playback of the connected signals without having to switch between them.

It features 30 W RMS for the woofer and 25 W RMS for the tweeter, with a frequency range of 50 to 20,000 Hz. The microphone input includes switchable 48 V phantom power and effects, while the instrument input offers gain control, a switchable Hi-Input mode, and its own effects with intensity adjustment. The tone controls and mute button allow you to adapt and silence the sound from the device.

In addition to amplifying your instruments, it works as a Bluetooth 5.4 speaker with Auracast support for multi-speaker setups. Its built-in battery, splash-resistant casing, and accessory compartment make mobile use easy, with a built-in lamp that adds fixed light, car, and disco modes.
