Filtration: Your Secret Weapon

Get to know them!

The API 565 500 Series Filter Module is your secret weapon. Creative filtering can spell the difference between adequate and awesome. From an incisive notch filter to adjustable high and lowpass filters, the API 565 Filter can make your recordings shine. Offering both classic and modern filtering technology, the 565 is the perfect solution to all your filtering problems. And like all API products, it’s a precision device that belongs in every professional’s toolkit. Have you invested in the 500 Series format? Check out what the amazing API 565 Filter Module can do for you.

Filter with surgical precision

If you deconstruct the greatest sounds on some of your all-time favorite recordings, you’d be surprised how often filtration is the key. More often than not, cutting a specific frequency is more effective than boosting in other areas of the spectrum. A popular kick drum trick back in in the soulful ’70s, for instance, was a 12dB cut at 400Hz on an API 550 EQ. Now API gives you a tool designed specifically for filtration with surgical precision — and, of course, it’s got that classic API analog mojo. With highpass, lowpass, and a variable notch filter with adjustable Q that’s fully sweepable between 20Hz and 20kHz, the API 565 is your new secret weapon. Put one or more in your 500 Series rack.

A legacy of iconic sound

Have you heard an audio pro lament something to the effect that “they don’t build ‘em like they used to”? Well, after more than a half century, the golden age of analog at API is still going strong. At Sweetwater, we know that today’s best pro audio equipment is actually built to higher standards than back in the day. Stringent, computer-assisted manufacturing tolerances and reliable modern components deliver problem-free audio with generous headroom and the vintage-flavored sonics we all love. Case in point: the 565 Filter Bank module incorporates circuits that are true to the highly musical filters used in the famed 215 module found in iconic API large-format consoles, as well as the discrete transistor buffers as used in the company’s famous 550 series equalizers.

API: the legendary American pro audio company

No American pro audio company is more iconic than API. Launched in 1968 by Saul Walker, Automated Processes Inc. began building quality consoles for broadcast applications. Soon, the company’s products found favor with recording studios, and a string of industry-leading innovations (including the 500 Series module, the first VCA, computerized console automation, and more) followed. API produced the 2520 amplifier, one of the most famous op-amps in the recording industry, and their consoles and products found homes in such iconic studio facilities as the Hit Factory, Record Plant, Ocean Way, Sunset Sound, and many others.

In fact, there are over 700 vintage API consoles around the globe — many of which are still in use. And the company certainly isn’t resting on its laurels; today’s API products give you the same unbeatable combination of utility, innovation, and great sound. That’s why, at Sweetwater, the name API commands reverence.
