Independent shopping perspective
The Korena take
Two-channel passive direct box for converting instrument-level signals to balanced XLR. For anyone running keys, bass or stereo sources into a mixer.
Strong match
Who this is for
- Stereo keyboard rigs needing two balanced XLR sends to front of house
- Bass players splitting to an amp and the board
- Long cable runs from stage to mixer without hum or level loss
Consider the trade-offs
When to look elsewhere
- Passive pickups needing high input impedance; an active DI suits those better
- Anyone wanting only one channel — you're paying for two
- Players needing built-in preamp gain for very quiet sources
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
Dual channel
Handles a stereo source or two separate instruments from one box, saving space on a crowded stage.
Detail 03
Transformer isolation
Breaks ground loops between stage and console, which kills the hum you get from shared grounds.
Detail 04
Unbalanced to balanced conversion
Lets you run long XLR cable to the mixer without the noise and treble loss of a long instrument cable.
Final check
Know before you order
- 01XLR and instrument cables are not included — budget for four cables
- 02Passive DIs suit hot signals like keys; quiet passive pickups may prefer active
- 03Check whether your board's ground-lift is needed before chasing hum elsewhere
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Does this need power or a battery?
No. It's a passive DI, so it runs on the signal itself with no battery or phantom power.
02Can I use it for a stereo keyboard?
Yes. It's a dual box, so left and right each get their own channel and XLR output.
03Will it fix hum from my stage rig?
Transformer isolation breaks ground loops between stage and console, which is the usual source of that hum.
04Passive or active — which do I need?
Passive works well with strong signals like keyboards and active basses. Quiet passive pickups generally do better with an active DI.
