Independent shopping perspective
The Korena take
A passive two-channel DI for getting keyboards, laptops or playback rigs into a mixer over long XLR runs. For stage and AV work.
Strong match
Who this is for
- Sending a stereo keyboard or laptop into a house console
- AV rooms where a mixer sits far from the source
- Passive rigs where no power outlet is available
Consider the trade-offs
When to look elsewhere
- Players needing a single-channel DI for one instrument
- Anyone wanting onboard preamp gain or tone shaping
- Setups that already run balanced outputs to the board
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
Balanced 600-ohm mic-level output
Drops the signal to mic level so it survives 100-foot XLR runs into any mixer channel without hum.
Detail 03
High-Z unbalanced input
Takes an instrument or line-level consumer output directly without loading down the source.
Detail 04
-15dB input pad
Cuts hot outputs from keyboards and playback devices so the transformer does not distort.
Detail 05
20Hz to 20kHz +/- 2.5dB
Full-range enough for keys and playback, not just guitar. Bass and cymbal content both pass.
Detail 06
0.01% THD
Adds essentially nothing audible of its own. What goes in is what reaches the console.
Final check
Know before you order
- 01Two XLR cables needed, one per channel, for a true stereo feed
- 02Passive design, so it takes no phantom power and adds no gain
- 03Engage the pad first if the source output is hot
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Does it need phantom power?
No. It is passive and takes no power at all, so it works with consoles that have phantom off.
02Can I run a stereo keyboard through one box?
Yes. It is a two-channel box, so left and right both go through it and out as two balanced XLR feeds.
03Will it work with a laptop headphone output?
Yes. The high-Z unbalanced input accepts that signal, and the -15dB pad handles it if the level is hot.
04How long a cable run can it handle?
The balanced mic-level output is what long runs are for. Standard XLR snake lengths to front of house are fine.
