DI Boxes

Radial Engineering offer a range of Active and Passive DI Boxes designed to handle the most abusive touring environments and to address the needs such as acoustic guitar, bass, computers and even turntables.

The Active DI Boxes are legendary in their ability to handle more signal level with less distortion and quietly transfer the sound of the instrument to the audio system without artifact.

The Passive DI Boxes provide lower noise, less distortion and greater signal handling with a choice of custom wound Radial transformers or the world's finest Jensen audio transformers.
