Detail 01
Active circuit, not passive
It needs power to run, but presents a high input impedance so passive pickups keep their top end.

BehringerULTRA-DI DI100 Active Direct Box
1/5
Independent shopping perspective
The Korena take
An active DI box that turns an instrument or line signal into a balanced XLR feed for a mixer or snake. Basic stage and studio utility.
Strong match
Who this is for
- Sending bass or acoustic guitar to a mixer over a long cable run
- Splitting a keyboard or laptop output to front of house
- A backup DI to keep in a gig bag or studio drawer
Consider the trade-offs
When to look elsewhere
- Anyone wanting a transformer's galvanic isolation to kill ground hum
- Engineers chasing a specific coloured or vintage DI tone
- Setups with no phantom power or battery available
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
10Hz to 90kHz frequency response
Far wider than the audible range, so it stays flat across everything you feed it without shaping the sound.
Detail 03
−102dBu noise floor
Quiet enough to sit in front of a preamp without adding audible hiss to a clean signal.
Detail 04
Balanced XLR output
Converts an unbalanced instrument cable to a balanced feed, so 50-foot runs to the board stay hum-free.
Final check
Know before you order
- 01Active design needs power — phantom from the desk or a battery, not bus power
- 02No cables included; you supply the instrument cable and the XLR run
- 03Handles one channel, so a stereo keyboard needs two boxes
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Active or passive DI — which do I need?
Active, like this one, suits passive pickups and instruments with weak output because its high input impedance preserves treble. Passive boxes suit hot line-level sources and need no power.
02Does it need phantom power?
It is an active box, so it requires power to operate. Phantom power from the mixer is the usual source when a battery is not available.
03Will it fix a ground hum?
Not reliably. Hum from ground loops is best solved with a transformer-isolated DI or by fixing the power path. This one converts and balances the signal.
04Can I use it with a keyboard or laptop?
Yes, for one channel. Stereo sources need a second box or a two-channel DI to carry both sides to the mixer.
