Detail 01
Passive design
No power or battery needed. Works anywhere, but the transformer costs you a little signal level.

Independent shopping perspective
The Korena take
Passive DI box that converts an instrument-level unbalanced signal to balanced XLR for long cable runs into a mixer or interface.
Strong match
Who this is for
- Bass or keys into a stage snake without hum
- Sending a guitar amp's speaker-level tap to front of house
- Getting an unbalanced source 50+ feet to a mixer
Consider the trade-offs
When to look elsewhere
- Passive pickups needing gain — a passive DI adds none
- Anyone wanting phantom-powered active circuitry for high-impedance sources
- Studios needing a colored, tone-shaping DI
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
Transformer-isolated
Breaks the ground path between stage and console, which is what kills buzz on long runs.
Detail 03
Instrument to balanced XLR
Balanced output rejects noise picked up along the cable, so length stops mattering much.
Detail 04
Under $60
Entry pricing for a utility box you will own for years and rarely think about.
Final check
Know before you order
- 01No XLR cable included — you supply the run to the mixer.
- 02Passive DIs suit hot sources; weak active pickups may sound quiet.
- 03Check whether your source needs a ground lift for buzz.
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Does this need phantom power?
No. It is passive, so it runs entirely off the signal passing through it. Phantom power on the mixer channel will not harm it, but it is not required.
02Can I use it with a bass?
Yes. Bass into a mixer or interface is the most common use for a DI like this.
03Passive or active DI — which do I need?
Passive works well with strong signals: basses with hot pickups, keyboards, amp outputs. Active DIs suit weak, high-impedance sources that need a gain boost.
04Will it fix hum from my amp?
It can. Isolating the ground between your rig and the console removes the loop that usually causes hum on stage.
