API Audio 560 10 Band Graphic EQ in Lunchbox Format

General

The API Audio 560 10 Band Graphic EQ is a modern classic that helps you through those more difficult EQ tasks. Originally developed for the API studio mixing panels from the 60s and 70s, this lunchbox-format model is made for the modular API-500 system with which you can assemble a bespoke rack or mixing table. This capable EQ helps with trickier tasks and makes things quick and easy when forming and restoring settings. Compared to the original, this 560 has an improved resolution at +/- 4dB while retaining that same unique API sound.

Due to the clear, familiar structure of this graphic equalizer, shaping curves is actually a pleasure. The 560 is fitted with a 2520 Op Amp that offers a lot of headroom and maintains a consistent performance even when the EQ settings get extreme. The 2520 amp can process input signals with a low impedance resulting in an immediately noticeable improvement in the reproduction of low frequencies and a tighter sound image. This gives that legendary 'thump-in-your-gut' sound. The 560 is also known for its Proportional Q which, as you increase or decrease the frequency, narrows the bandwidth, so the higher the boost or cut, the narrower the Q. This allows you to make incredibly accurate adjustments. and minimizes the phase-shift sound that other equalizers will tend to produce.

Advantages of the API-500 Lunchbox Format

API introduced the lunchbox format. This is a modular system that lets you choose the high-quality peripherals you want that can then be easily installed into a single rack. It's known as the API-500 format. Being able to choose the components you want is one of the biggest advantages of this system. Another one is the fact that everything can be powered from the rack itself which saves you money because you don't have to buy separate power supplies for all the parts you choose. It's also handy to have everything installed in a single rack because it's much neater and more portable too.
