What Does a DI Box Do?
A DI (Direct Injection) box converts an unbalanced, high-impedance signal from instruments into a balanced, low-impedance signal suitable for professional audio equipment. This helps reduce electrical interference, hum and signal degradation, especially when using long XLR cables to connect to mixers or stage boxes.
Passive Design – No Power Required
This is a passive DI box, meaning it operates without batteries or phantom power. Simply connect your instrument and you’re ready to play. Passive DI boxes are an excellent choice for active guitars, keyboards, digital instruments and line-level audio sources.
Ground Lift Switch for Cleaner Audio
Ground loop hum is one of the most common problems in live audio setups. The built-in Ground Lift switch disconnects the audio ground when needed, helping eliminate unwanted buzzing and electrical interference without affecting your signal quality.
Selectable PAD Attenuation
The integrated attenuation switch allows you to reduce hot input signals when connecting high-output instruments or audio devices.
- 0 dB – Standard instrument signals
- -20 dB – Medium output sources
- -40 dB – High-level line outputs and powered devices
This prevents input clipping and distortion when connecting to mixers or recording equipment.
Balanced XLR Output
The balanced XLR output provides a clean, low-noise connection to:
- Mixing consoles
- PA systems
- Audio interfaces
- Recording equipment
- Stage snakes
Balanced connections significantly reduce electromagnetic interference and maintain signal integrity over long cable distances.
1/4″ Link (Thru) Output
The dedicated Thru output allows you to send your original instrument signal to your amplifier while simultaneously sending a balanced signal to the front-of-house mixer or recording interface. This is perfect for live performances where you want to hear your amp on stage while providing a clean signal to the sound engineer.
Built for Touring and Stage Use
Constructed from rugged metal, the enclosure is designed to withstand regular transport, rehearsals and demanding live performances. Its compact size makes it easy to fit into pedalboards, gig bags or studio setups.

Frequently Asked Questions
Do I need power for this DI box?
No. This is a passive DI box and does not require batteries or phantom power.
Can I use this with an electric guitar?
Yes. It works perfectly with electric guitars, basses, acoustic guitars with pickups and many other instruments.
What’s the difference between a passive and active DI box?
Passive DI boxes require no power and are ideal for active instruments, keyboards and line-level devices. Active DI boxes require power but are often preferred for passive pickups with very high impedance.
Can I connect this to a mixing console?
Yes. The balanced XLR output is specifically designed for mixers, PA systems and recording interfaces.
What is the Thru output used for?
The Thru output sends the original instrument signal to your amplifier while the balanced XLR output goes to the mixer, making it ideal for live performances.
