Direct Boxes

Direct boxes (DI boxes) convert unbalanced, high-impedance signals from guitars, basses, keyboards, laptops and playback devices into balanced, microphone-level signals that can travel long distances to a mixer without noise or tone loss. They are one of the most important problem solvers on any stage or in the studio.

This category covers passive DI boxes, active DI boxes, stereo and dual-channel DIs, USB DI boxes for computers and Bluetooth DI boxes for wireless playback. Ground-lift switches and pads help eliminate hum and handle hot signals.

Types of direct boxes

Passive DI boxes for active pickups, keyboards and line sources
Active DI boxes for passive pickups and low-level instruments
Stereo and dual-channel DIs for keyboards and playback
USB and Bluetooth DI boxes for computers and phones

Who buys direct boxes

Live sound engineers, bands, worship teams, studios, DJs, presenters and rental companies use direct boxes on almost every show.

What to look for in direct boxes

Active or passive design to suit the source
Number of channels: mono, dual or stereo
Ground lift, pad and through/link outputs
Power: phantom power or battery for active models

Direct Boxes: questions and answers

When do I need a DI box?

Use a DI box to connect instruments, keyboards, laptops and playback devices to a mixer's microphone inputs over long balanced cables without noise or tone loss.

Should I choose an active or passive DI?

Active DIs suit passive guitar and bass pickups and low-level sources. Passive DIs suit keyboards, active pickups and hot line-level sources. Both are useful on stage.

What does the ground lift switch do?

The ground lift disconnects the ground between the input and output side of the DI, which can remove hum caused by ground loops.

Can your personnel help me choose direct boxes?

Yes. Our personnel can advise you on direct boxes for your application. Call +91 89818 07755 or +91 91477 00677, or visit our showroom in Dhakuria, Kolkata, West Bengal, India.
