4DI - A DI Solution to Die For!
Hazelrigg Industries has expanded its acclaimed Solution Series with the new 4DI, a powerhouse addition to a lineup that includes the VLC, VNE, VEC, and VDI. This innovative unit combines four channels of Doug Fearn’s renowned VT-I/F Direct Injection Box circuits, all packed into a sleek 2-space rackmount design. It's an ideal choice for a wide range of applications, from Houses of Worship and live FOH (Front of House) setups to recording studios and beyond.
Unveiling the Classic All-Tube DI Circuitry
The 4DI is a modernized take on the legendary D.W. Fearn VT-I/F, now featuring four channels of the classic all-triode vacuum tube direct box design. While the original VT-I/F offered two channels, this new iteration expands the utility with four independent channels, all housed in a compact 2-space rackmount unit. Whether on stage or in the studio, the 4DI delivers rich, dynamic sound quality for a variety of instruments.
Features Designed for Versatility
The 4DI is packed with features that make it highly versatile and easy to use:
- Front Panel Controls: The 4DI’s front panel sports four locking ¼” instrument inputs, each with its own ground lift switch and signal indicator LED, ensuring easy access and monitoring.
- Rear Panel Connectivity: On the rear, there are four sets of ¼” input and passthrough jacks (wired in parallel to the front panel connectors), alongside four microphone level outputs on XLR connectors.
- Power Flexibility: The rear panel also houses an IEC mains socket, power switch, and a 115V-220V mains selector for easy power adjustments.
Stunning Sound Quality for Studio and Stage
Sharing the same high-headroom, all-triode circuit design as the VT-I/F, the 4DI guarantees exceptional audio fidelity and responsiveness. It’s particularly well-suited for a range of applications, including:
- Electric Bass and Guitar: Experience impressive clarity and dynamic response with electric instruments.
- Synthesizers: Add fullness and vintage warmth to both analog and digital synths.
- Acoustic Instruments: Achieve a new level of depth and realism, particularly with piezo-equipped instruments.
