Detail 01
31 bands
Roughly third-octave spacing across the audio range. Fine enough to pull down one ringing frequency without gutting nearby content.

Independent shopping perspective
The Korena take
A mono 31-band equalizer for correcting a room or taming feedback. Aimed at live sound and install work rather than creative tone shaping.
Strong match
Who this is for
- Notching feedback frequencies in a live PA
- Tuning one monitor wedge or one side of a system
- Fixed installs where you set curves once and leave them
Consider the trade-offs
When to look elsewhere
- Stereo systems, unless you buy two units
- Guitarists wanting broad, musical tone sweeps — this is surgical
- Anyone who wants recallable presets between different rooms
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
Single channel
One signal path only. A stereo rig or a left-right PA needs two units, doubling cost and space.
Detail 03
Graphic-style band layout
You read the whole curve at a glance, which matters when you are correcting under time pressure at soundcheck.
Detail 04
Analog, no presets
Settings live in the physical positions. Photograph the panel if you move between rooms with different acoustics.
Detail 05
$169.99 for 31 bands
Cost per band is low. The tradeoff versus digital units is no memory, no delay, and no measurement tools.
Final check
Know before you order
- 01One unit covers one channel only; a stereo system needs two
- 02Steep cuts at many bands can drop overall level; check gain staging
- 03Plan where it sits in the chain relative to crossovers and amps
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Is one enough for a stereo PA?
No. This is a single-channel unit, so it processes one signal path. Stereo or separate left and right system tuning requires two of them.
02What is 31-band good for that a 15-band is not?
Roughly third-octave resolution. You can pull one problem frequency down while leaving the neighbors alone, which matters for feedback control.
03Will it fix a bad-sounding room?
It corrects tonal balance and tames ringing frequencies. It cannot fix reflections, flutter echo, or bass buildup caused by room dimensions.
04Can I use it with a guitar amp?
It is built for line-level signal processing rather than instrument-level pickup output. Feed it from a driven output, such as an effects loop send.
