Dbx Professional / Harman DBXDI1 Direct Injection Box

Product Description

The DBX PROFESSIONAL / HARMAN DBXDI1 is a direct injection box designed for audio signal processing applications. A DI box converts unbalanced, high-impedance instrument-level signals to balanced, low-impedance signals suitable for connection to professional mixing consoles, audio interfaces, and PA systems. This unit is sold individually and is used by audio engineers, live sound technicians, and recording professionals in studio and live sound environments.

The DBXDI1 is suited for both live performance and studio recording scenarios where a clean, hum-free signal path is required. It bridges the gap between instruments such as electric guitars, basses, and keyboards and professional balanced audio equipment. Installation and setup are handled by audio technicians and live sound engineers working in amplifier and signal processing chains.

Key Features

• Converts unbalanced high-impedance signals to balanced low-impedance output
• Designed for use in professional amplifier and audio signal processing setups
• Sold as a single unit (each)

Installation Notes

Installation is typically performed by a qualified audio technician or live sound engineer. Power down or mute the connected audio system before connecting or disconnecting the unit to avoid signal pops or equipment damage. Follow standard professional audio wiring practices and consult equipment manuals for proper gain staging when integrating into an existing signal chain.
