Independent shopping perspective
The Korena take
Rack crossover that splits one signal into frequency bands for separate amps. For anyone running bi-amped or tri-amped speakers without built-in DSP.
Strong match
Who this is for
- Bi-amping passive PA tops and subs with separate power amps
- Small live rigs needing a hardware crossover instead of a DSP processor
- Fixed installs where a set-and-forget analog box beats a menu system
Consider the trade-offs
When to look elsewhere
- Powered speakers that already crossover internally
- Anyone wanting delay, EQ, or presets — this splits bands only
- Guitar players expecting a pedal; it is 19-inch rack gear
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
XLR in and out
Balanced connections throughout, so long runs to amp racks stay quiet. TRS or 1/4-inch gear needs adapter cables.
Detail 03
40Hz high-pass, 12dB/octave
One switch per channel pulls subsonic rumble off the low band, protecting drivers from stage thump and handling noise.
Detail 04
Phase invert per output
Flips polarity on individual bands to fix cancellation where drivers meet, a common fix when subs and tops null at crossover.
Detail 05
1U, 19 inches wide
One rack space in a standard rack. Front-panel controls stay reachable, but so do accidental bumps at a busy gig.
Detail 06
100-120V or 230V operation
Confirm the voltage on the unit you receive matches your outlet. Analog gear at the wrong voltage is a one-time mistake.
Final check
Know before you order
- 01No XLR cables, rack screws, or power cable extras included
- 02Set crossover points to your speakers' rated ranges before powering amps up
- 03Needs a rack or shelf; front controls are exposed and easy to knock
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Do I need this if I have powered speakers?
Usually not. Powered tops and subs handle band splitting internally. This is for passive speakers driven by separate power amps.
02Can I run subs and tops with this?
Yes. That is the common two-way stereo setup: lows to the sub amp, highs to the top amp, with the 40Hz filter guarding the low band.
03Does it have EQ or delay?
No. It splits frequency bands, inverts phase per output, and offers a 40Hz high-pass. Time alignment and EQ need a separate processor.
04How much rack space does it take?
One rack unit at 1.75 inches tall and 19 inches wide, with 6.9 inches of depth behind the panel.
