Detail 01
2 in, 6 out
A stereo feed drives up to three-way biamped stereo or a mono three-way rig. Six amp channels, not six speakers.

dbxDrive Rack 260 with RTA-M Reference Mic
1/6
Independent shopping perspective
The Korena take
A loudspeaker management processor with the measurement mic included. For anyone tuning and protecting a PA system rather than mixing on it.
Strong match
Who this is for
- Tuning a house PA to the room with real measurements
- Splitting a full-range mix into biamped tops and subs
- Protecting rented or house speakers from operator overdrive
Consider the trade-offs
When to look elsewhere
- Guitarists — this is not a pedal or an amp processor
- Small powered-speaker setups with onboard DSP already handling crossover
- Anyone wanting recording effects like reverb or delay
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
RTA mic input with +15V phantom
The included reference mic powers off the unit, so no separate preamp or 48V supply is needed for room tuning.
Detail 03
48 kHz sample rate
Standard for live sound. Full 20 Hz–20 kHz response; this is a live-rig processor, not a mastering converter.
Detail 04
+22 dBu max output
Plenty of headroom to hit any pro power amp's input to full drive without the processor clipping first.
Detail 05
0.002% THD+N, 110 dB dynamic range
Sits transparently between console and amps — you should not hear it working, only what it corrects.
Detail 06
Male XLR connectors
Standard balanced pro runs. Budget XLR cables for every output; a six-out rig needs more cable than people expect.
Final check
Know before you order
- 01Goes between mixer and power amps — it does not amplify anything itself
- 02Wrong crossover or limiter settings can damage speakers; know your driver limits
- 03Rack ears and XLR cables for the amp runs are your own supply
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01What does the RTA mic actually do?
You place it in the room, run the auto-EQ wizard, and the unit measures the system's response and applies corrective EQ to flatten it.
02Do I need this with powered speakers?
Usually not for crossover — powered boxes handle that internally. It's still useful for room EQ, delay alignment, and limiting.
03Does it replace a mixer?
No. It has two line inputs and no mic preamps or faders. It sits after the mixer, before the amps.
04Can it time-align subs and tops?
Yes — output delay is part of what loudspeaker management does, alongside crossover, EQ, and limiting.
