Detail 01
1200W per channel at 4 ohms
Drops to 650W per side into 8-ohm cabs. Know your cabinet impedance before you judge whether this is enough.

Independent shopping perspective
The Korena take
Two-channel power amp with onboard DSP, 1200W per channel at 4 ohms. For a working PA or small install that wants crossovers and limiting built in.
Strong match
Who this is for
- Running mains and a sub from one rack space
- Mobile bands and DJs loading in and out weekly
- Small installs where presets get set once and locked
Consider the trade-offs
When to look elsewhere
- Home stereo use — fan noise and XLR-only inputs
- Studio racks in the same room as microphones
- Large subwoofer arrays that need more headroom
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
Rated down to 2 ohms
You can parallel two 4-ohm cabs per channel and still get 1600W a side, instead of buying a second amp.
Detail 03
Crossovers, delay and limiter onboard
Runs a main-plus-sub rig with no outboard processor. The 50ms of delay covers driver alignment or a short delay fill.
Detail 04
1.4 Vrms sensitivity
It hits full power at ordinary mixer levels, so the front knobs sit well below max. Set gain structure or you clip early.
Detail 05
18.5 lb in 2U
Light enough to rack two and still carry the case. The fan pulls front to rear, so leave air behind the rack.
Detail 06
10.5A under program, 38W idle
One amp is fine on a 15A circuit. Two, plus lighting, is not — plan the power before load-in.
Final check
Know before you order
- 01Speakon and XLR cables are not included
- 02Bridged operation is rated to 4 ohms — do not go lower
- 03Deep DSP editing runs over USB from a computer
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Can I run two speakers per channel?
Yes, if the parallel load stays at 2 ohms or above. Two 4-ohm cabs per side gives 1600W per channel. Two 8-ohm cabs land at 4 ohms.
02Do I still need a separate crossover for my sub?
No. Each channel has highpass and lowpass filters with Butterworth and Linkwitz-Riley slopes, plus bandpass gain and polarity, so you can split mains and sub in the amp.
03How do I change the DSP settings?
The USB Type B port connects it to a computer for setup and preset editing. It holds 30 presets, 29 of which you can define yourself.
04Can I bridge it into one subwoofer?
Yes — 3200W into 4 ohms bridged, 2400W into 8. Bridging uses both channels, so you lose the second output for mains.
