Description
Description
The Radial HDI is a new studio DI featuring an oversized Jensen custom transformer and unique COLOR control.
By turning the COLOR control in the center of the unit, you can intuitively blend clean sounds with saturated distortion sounds.In addition to a 1/4 TS phone input for connecting bass or acoustic guitar, it is equipped with a 3.5mm mono input that can handle high signal levels such as from modular synths.
In addition to the balanced mic-level output found on typical DIs, the XLR output also provides a line-level output with a maximum of +25dBu. These XLR outputs are independent of each other, so you can simultaneously supply a mic-level output to your favorite mic preamplifier and a line-level output to an audio IF.
Main features: Intuitive sound settings, ultra-clean to distortion blend, OPTO compressor to suppress peaks, mic and line level outputs, extra-large Jensen custom transformer
