Hazelrigg Industries 4DI Vacuum Tube 4-channel Direct Injection Box

Introducing the Hazelrigg Industries 4DI Vacuum Tube 4-channel Direct Injection Box, a groundbreaking achievement in professional audio engineering. This multi-channel DI unit brings together the richness and warmth of vacuum-tube sound with the precision and reliability required by today’s audio professionals.

Key Features and Benefits:

1. Four Vacuum-Tube Channels: Each of the four channels harnesses the power of vacuum-tube technology to deliver a warm, harmonically rich sound. This makes the 4DI ideal for a variety of instruments, including electric bass, guitar, keyboard, modular synths, and acoustic instruments with pickups.
2. Optimized for Professional Recording: Unlike passive transformer-style direct boxes, the 4DI is designed for dynamic professional recording, offering optimal load impedance and superior sound reproduction across a wide range of instrument levels.
3. Premium Construction: Handcrafted in the USA, the 4DI is built with top-quality components like custom Jensen output transformers. The unit is housed in a durable 1/4-inch-thick aluminum plate, ensuring longevity and reliability, especially for touring and live sound applications.
4. Versatile Connectivity: The 4DI is equipped with Through jacks, per-channel Ground Lift switches, and locking 1/4-inch input jacks. Its transformer-balanced XLR outputs, IEC mains socket, and mains voltage selector (115V/230V) make it a perfect fit for any professional setup.
5. Superior Sound Quality: The all-tube circuitry and Jensen transformer-balanced output ensure that instruments like electric basses and guitars sound vibrant and responsive, closely mimicking the sound of being plugged into a high-quality tube amp.
6. Rackmount Convenience: With its 1U rackmount design, the 4DI is convenient for studio and live settings, fitting seamlessly into standard equipment racks.
7. Extended Warranty: The Hazelrigg Industries 4DI comes with a limited 7-year warranty, with a 90-day warranty for vacuum tubes, offering peace of mind and reliability.
8. Technical Specifications: The unit boasts a 1 Mohm minimum input load impedance, a frequency response of 10Hz–20kHz (±0.2dB), and THD + noise of less than 0.3%.

In conclusion, the Hazelrigg Industries 4DI is not just a direct injection box; it’s a testament to high-fidelity sound and robust construction. It stands as a pinnacle of audio technology, perfect for musicians and engineers who demand the best in their audio equipment.
