Radial Engineering HDI Studio Direct Box

While a standard DI simply balances your signal for a mixer or interface, the HDI acts as a creative tool. It includes an integrated opto-compressor and a unique Color control, allowing you to shape your tone, add warmth, or introduce tube-style distortion before the signal ever hits your preamp.

Yes, it functions effectively as a clean bass preamp. You can use the Color and Opto-Compressor controls to dial in your desired character, making it a great solution for recording bass directly into your interface.

No, the HDI is powered entirely by 48V phantom power from your mixer or audio interface. You do not need to worry about batteries or external power bricks.

It is designed to handle a wide range of sources, including electric and acoustic guitars, bass, synthesizers, and keyboards. Its versatile controls make it particularly useful for instruments that need a little extra character or dynamic control before recording.

The Color control introduces harmonic saturation, allowing you to move from a pristine, clean signal to a more aggressive, tube-like distortion. It is designed to add depth and grit to your signal, giving you more tonal options than a traditional, transparent DI.

Absolutely. The integrated opto-compressor provides smooth, musical dynamic control that works just as well on stage as it does in the studio. It helps tame peaks and even out your performance, ensuring a consistent signal sent to the front-of-house.
