Get to know them!

Yet another API modern classic, the 560 is a discrete 10-band graphic EQ - originally conceived for the API consoles in the 60s and 70s. This reissue is all about helping you achieve difficult equalization tasks. Not only does the API 560 give you that unique "API sound," but it also offers up incredible curve-shaping potential - especially when paired with a parametric EQ. Everything about the API 560 was born from the original - only this "new-old" version features improved resolution at +/- 4dB. You can use the API 560 within any API 500 Series chassis.

API 560 500 Series 10-band Graphic Equalizer at a Glance:
  • A reissue of a classic - 10 bands for serious sculpting with that "API sound"
  • API's "Proportional-Q" Control
  • API's 500 Series: Long-term flexibility, lasting value
A reissue of a 1960s/1970s classic - 10 bands for serious sculpting with that "API sound"

Originally conceived for use in API Consoles of the 60s and 70s, the API 560 reissue is a unique device designed to give you a deep level of track-sculpting capabilities. It delivers that "one-of-a-kind" API sound, precision easy set filtering, and high headroom, all in a very small package. Extremely fast to set and reset using accurate zero detents, the curve-shaping potential of the 560 is phenomenal. With a large number of available EQ bands, when you pair the API 560 with an API parametric EQ, you've got an unbeatable system for carving and sweetening. At home both in field recording and the studio environment, this "new-old" version is a re-issue of the original 560 with improved resolution in the critical area of +/- 4dB. As you'd expect, the API 560 incorporates API's exclusive circuitry and proprietary components (such as the legendary 2520 op-amp), artfully blending the past with the present, layout with function.

API's "Proportional-Q" Control

Making use of "API Proportional-Q", a design introduced by API in the 60s, the 560 intuitively widens the filter bandwidth at minimal settings and narrows it at higher settings - without the need for additional bandwidth controls. This feature minimizes the "phase-shift" sound found in many equalizers.

API's 500 Series: Long-term flexibility, lasting value

The beauty of the entire API 500 Series is its long-term flexibility and lasting value - especially when you consider that needs change over time. With a range of mounting frame options, the API 560 will be a valuable asset to your ever-changing studio rigs. It's also ruggedly designed with sound you just won't outgrow - crafted to be your sonic partner for year after year after year.

What is Certified Open Box Gear?

At Sweetwater, we're so picky that what we call "Certified Open Box" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

Certified Open Box (also known as a demo) means we’ve had it out of the box for our YouTube channel, displayed at events, tested in our studio, or maybe it was in a customer’s hands for a few days and isn’t ‘factory fresh’ as a result. Every Certified Open Box item we sell has Sweetwater’s 2-year Total Confidence Coverage™ warranty and has been tested and verified up to ‘new’ specs by our factory-authorized technicians to make sure it’s in perfect working order before we ship it to you.

When you buy a Certified Open Box item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!

The payments equal the amount financed divided by the number of months in the promo period, rounded up to the next whole dollar. These payments may be higher than the payments that would be required if this purchase was a non-promo purchase. During the last month(s) of the promo period the required monthly payment may be reduced due to the prior months’ rounding. Regular account terms apply to non-promo purchases.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
