Best 500 Series Preamps

best 500 series preamps

API is known as one of the most legendary companies in music technology history, but during music’s golden age of the mid 1960s they were just another startup. The company innovated an idea of smaller, modular units that could be swapped in and out of their large frame consoles. This made repairs easier to perform as the channels could be broken down by section, but also allowed engineers to integrate units from other companies into their consoles for tonal variation.

Though API was out of business by the late 70s (don’t worry, they came back with a vengeance!) other companies proudly took the baton and soldiered on with the idea and even took it a step further. Enter the “lunchbox”. Over the next few years multiple companies created their own versions – all based on the same “interchangeable parts” approach. A while after API was resurrected by a change of ownership, it created the VPR Alliance which established regulations and standards to approve the creation of 500 series units by different manufacturers.

500 series units are amazing because you can build out your dream signal chain easily without needing a cumbersome console and integrate it into your interface based digital audio ecosystem. A number of companies are represented here, each with their own take on a 500 series preamp. While some are not exactly inexpensive, they all fall in the under $1000 range.

Here are some of the best 500 series preamps.

Black Lion Audio B173

Appropriately named, the Tone Beast from Warm Audio provides a variety of preamps in one two-space unit. There are a number of ways to shape the signal. A switch offers selection of two options for the CineMag output transformers with steel and nickel that provide distinctly different character. What’s more, you can also take the output transformer out of the signal altogether. Choose between two styles of op-amps for clean or more saturated sounds, and two types of capacitors (tantalum or electrolytic). Additionally, there is an insert point for routing it with other gear. No matter if your source needs a mic, line, or DI input this preamp offers versatile, beastly tone.
