Description
Experience the pinnacle of direct box technology with the Radial HDI Studio Grade 1-channel Active Instrument Direct Box. This studio-quality gem is designed to bring out the best in any instrument, boasting premium Jensen transformers and an innovative Color control feature. Whether you're a purist seeking that pristine tone or an adventurer chasing gritty, amp-like distortion, the HDI caters to all. The Color knob seamlessly blends clean and colored sound, offering a wide sonic palette for any musician or engineer to explore.
The HDI's elegance lies in its simplicity, with a straightforward set of controls that make dialing in a record-ready sound a breeze.

It's not just about looks; the HDI is engineered to deliver consistent performance, offering both mic and line-level outputs for versatile applications. The intuitive VU meter provides instant visual feedback, ensuring your levels are always just right.
