500 series modules are a great way to add analog processing to your signal chain, without breaking the bank or taking up too much space in your studio. Since they were introduced in the 1970s, 500 series preamps have been defining the sound of hit records and been a secret weapon to engineers. The design started with API, and since all their consoles were modular, you could easily swap out a preamp, EQ, or compressor if one were to go bad. Manufacturers started to see how this could benefit multiple aspects of the recording industry, and in the 1980’s, the 500 series was born. Vintage King offers the widest variety of 500 series modules, from API, NEVE, BAE, Focusrite, Moog, and many more. Modules come in everything you would need for recording or mixing from preamps, EQ, effects, compressors, gates, and more.

500 series modules are a perfect fit for integration into your favorite DAW, the modules offer the same sonic quality as their larger counterparts, but for fraction of the price, and much less real estate in your rack. Our sales engineers have been putting these modules to the test in pro recording facilities and home setups for years, and have experience with every module, so if you're unsure what you need to fill your first 500 series rack, we are here to help.

A bit of pre-planning is always in order when purchasing analog gear. Vintage King offers a variety of 500 series racks, From API, BAE, NEVE, SSL, Shadow Hills, and more, each with their own power specifications. Be sure to ask your sales engineer which will best suit the power requirement and voltage control for your selected gear.
