Teenage Engineering EP-35 K.O. Amp
The Teenage Engineering K.O. Amp 35 is a portable, battery-powered speaker designed for music production, recording, monitoring, jam sessions and everyday listening. Combining a 30 W RMS woofer and 25 W RMS tweeter with a range of audio connections, it provides a versatile solution for musicians, producers and performers.
Connect microphones, guitars, bass guitars, synthesizers, drum machines and other audio equipment directly to the speaker. The XLR microphone input features adjustable gain, switchable 48 V phantom power and built-in microphone effects, while the 6.3 mm instrument input offers gain adjustment, switchable Hi-Input mode and dedicated effects. A 3.5 mm stereo line input accommodates additional equipment, with all connected sources able to play simultaneously.
Bluetooth 5.4 connectivity enables wireless audio streaming, with Auracast support for multi-speaker configurations. The USB-C device connection also provides a built-in audio interface for computers, smartphones and tablets, alongside a 45 W charging function. A separate USB-C host port supports compatible audio devices, USB storage playback and optional accessories.
Designed for portable use, the K.O. Amp 35 features a built-in lithium-ion battery, splash-proof housing and integrated camp lamp with car, constant light and disco modes. A dedicated accessory compartment keeps smaller items stored away, while mounting points allow additional carrying accessories to be fitted.
With its compact construction, flexible connectivity and integrated sound controls, the K.O. Amp 35 brings together the functions of a portable speaker, instrument amplifier and audio interface in a single unit.
