It's rare to find a truly outstanding solid-state channel strip that can deliver a vintage vibe reminiscent of classic high-end products, yet employs a thoroughly modern design. To find one that you can buy without heavily depleting your bank account is even more rare. But there is one channel strip that delivers the goods without the big tab: the PreSonus RC 500

The RC 500 combines the custom-designed FET compressor and semi-parametric EQ circuits that Creel developed for PreSonus’ highly lauded ADL 700 tube channel strip with his new ultra-low-distortion, high-gain, solid-state Class A preamplifier design, which delivers consistent, repeatable, transparent, detailed audio. A balanced analog insert sends the source signal out of your RC 500 before the compressor, EQ, and Master Gain stages and returns the signal directly to the compressor stage, allowing you to add external processors. 

The result is a top-of-the-line — yet very affordable — channel strip for recording engineers and recording musicians, with a sound that is reminiscent of classic, vintage solid-state preamps

The RC 500’s FET (Field-Effect Transistor) compressor includes fully variable attack, release, and threshold controls, as well as bypass controls. The compression ratio is fixed at 3:1. This combination provides lots of flexibility without giving you enough rope to hang yourself!

User tip: The input-gain stage can be driven harder with a lower threshold to emulate higher compression ratios. You can make the RC 500 compressor pump if you want to.

As noted earlier, this compressor design is also found in the ADL 700 and has drawn rave reviews. For example, Hugh Rabjohn (Sound on Sound, August 2013) remarked, "The compressor is accurate and responsive, and very good for managing the normal dynamic excursions of most vocal performers, subtly but firmly."
FET-based compressors such as the one in the RC 500 use transistors to emulate a triode tube’s operation and sound. This type of compressor generally provides a faster attack time and better repeatability than the optical compressors that are more commonly found in channel strips in this price class.
