1/8
Independent shopping perspective
The Korena take
Rack crossover that splits a signal into 2, 3, or 4 bands before the power amps. For anyone running a passive multi-amp PA or bi-amped setup.
Strong match
Who this is for
- Bi-amping or tri-amping a passive PA with separate power amps
- Feeding a subwoofer its own amp channel with a proper split
- Fixed installs where an outboard split beats a DSP box
Consider the trade-offs
When to look elsewhere
- Powered speakers with built-in DSP crossovers — redundant
- Anyone wanting EQ, delay, or limiting alongside the split
- Guitarists — this is not a pedal or a tone shaper
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
x10 switch
Multiplies the frequency dial by ten, so one knob covers 45–960 Hz or 450 Hz–9.6 kHz.
Detail 03
LF sum switch
Sums the lows to mono so one subwoofer amp handles both channels while mids and highs stay stereo.
Detail 04
40 Hz high-pass, 12 dB/octave
Cuts subsonic rumble and stage thump below the useful range, saving amp headroom and cone excursion.
Detail 05
Phase invert per output
Flips polarity on any single band, which fixes cancellation when a driver or cabinet is wired backwards.
Detail 06
1/4 inch TRS, balanced
Balanced runs to amps resist hum over distance, but you may need TRS-to-XLR cables for many amps.
Final check
Know before you order
- 01Needs one power amp channel per band per side — plan amp count first
- 02Set crossover points to your drivers' rated ranges or you will damage them
- 03Mains cable and rack screws aside, no interconnect cables are included
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Can I use this with powered speakers?
Generally no. Powered speakers already crossover internally. This is for passive cabinets driven by separate power amps, one amp channel per frequency band.
02Does it have XLR connections?
Connections are 1/4 inch TRS, balanced. If your amps take XLR, use TRS-to-XLR cables.
03How many rack spaces does it take?
One. It is 1.75 inches tall and a full 19 inches wide, with 6.9 inches of depth behind the panel.
04What does mono 4-way mode do?
It uses both channels on one mono signal to create four bands — for example sub, low-mid, mid, and high, each to its own amp.
