Packing Outboard Processing Into Small Places.

Originally developed by API in the late 1960s as a way to customize the tone-shaping options on their consoles, the 500 Series was opened up to third-party brands in 2006 with the creation of the VPR Alliance. The results were nothing short of staggering, as you can now put nearly any kind of outboard processor into a small footprint.

Engineers can now load up a portable 500 Series frame as a "lunchbox" with their favorite preamps and signal processors and take it to any studio they like, or record on the go.

Our selection of 500 series gear is comprehensive, with such great names like API, JDK Audio, DBX, Black Lion Audio, Rupert Neve Designs, Elysia, Radial Engineering, BAE, Vintech, and so many others.
