Detail 01
2100W per channel at 4 ohms
Roughly 75 percent more per side than the 4002, and 1200W each into 8-ohm cabs. Real headroom for subs.

Independent shopping perspective
Two-channel amp with the same DSP as the 4002 and 2100W per channel at 4 ohms. For subwoofers and larger PA rigs that outgrew a smaller amp.

Strong match

What matters in use
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 01
Roughly 75 percent more per side than the 4002, and 1200W each into 8-ohm cabs. Real headroom for subs.
Detail 02
Both channels drive one load. Enough for a large sub, but you give up the second output for mains.
Detail 03
This wants a dedicated 20A circuit. Idle draw alone is nearly five times the 4002's, so it stays warm doing nothing.
Detail 04
Shows the active preset and processing status, so you can confirm the right setup is loaded without hooking up a laptop.
Detail 05
Four inches deeper and 5.5 lb heavier than the 4002. Measure shallow racks and leave room for cables behind it.
Detail 06
Residual hiss stays under the room, so an idle system between songs does not announce itself through the mains.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
Only if you need the power. The DSP, connections and rack size match; you are paying for 2100W a side instead of 1200W, and heavier subs.
Yes — 3000W per channel at 2 ohms, so two 4-ohm cabs in parallel per side works. Watch the current draw at that load.
Yes. The LCD and the sel/prev/next buttons cover preset changes and front-panel lockout. The USB connection is for deeper editing.
One XLR per channel, plus a link-out that loops the signal to another amp. RCA or unbalanced sources need an adapter or DI first.
