Detail 01
Proportional Q
Small moves are wide and gentle; the curve narrows as you push toward full boost or cut.

API560 Discrete 10-Band Graphic EQ
Independent shopping perspective
The Korena take
A 500-series 10-band graphic EQ with ±12dB per octave band. For engineers already running a 500-series rack who want fast, broad tone shaping.
Strong match
Who this is for
- Broad tone shaping on drum buses, guitars and room mics
- Engineers who already own a 500-series chassis with free slots
- Tracking chains where you want EQ committed on the way in
Consider the trade-offs
When to look elsewhere
- Surgical notching of feedback or resonant ringing frequencies
- Anyone without a 500-series rack or API console
- Stereo work on a budget — you need two modules
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
±12dB per band
Enough range to reshape a source, not enough to erase a problem. It's a shaping EQ, not a repair tool.
Detail 03
Fixed octave centers, 31Hz to 16kHz
You pick the nearest band rather than sweeping to a frequency. Faster to use, less precise.
Detail 04
12dB per octave slope at full boost or cut
Neighboring faders overlap, so adjacent boosts add up. Two bands at +6 hit harder than you'd expect.
Detail 05
Clipping better than +28dBu, noise −95dBu
Wide headroom above nominal level, so you can drive it hard before anything breaks up.
Detail 06
1.5 x 5.25 x 6.75 inch deep, 60mA draw
One 500-series slot and modest current, so several can share a single rack supply.
Final check
Know before you order
- 01No rack or power supply included — chassis and PSU are separate purchases
- 02One module is one channel; stereo means buying and matching two by hand
- 03Needs 6.75 inches of clearance behind the rack panel
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01do I need a lunchbox for this
Yes. It's a module with an edge connector, not a standalone unit. It goes in a 500-series rack, a 2-slot or 10-slot API chassis, or an API console.
02is it mono or stereo
One channel per module. For a stereo bus you need two, and you set both by hand — there's no link between them.
03can I use it instead of a parametric EQ
For broad shaping, yes. For hunting a specific problem frequency, no — the ten centers are fixed at octave spacing and the range stops at ±12dB.
04how much can it boost
12dB up or down on any of the ten bands. Bands overlap, so stacking two adjacent faders gives you more than either alone.
