Critic Reviews

Waves RS56

soundonsound.com

The Waves RS56 Passive EQ impresses with its sweet, natural sound, reminiscent of a classic console channel strip, making it perfect for adding warmth and color to mixes. Its M/S mode is notably handy for mastering, allowing for nuanced tonality adjustments without disturbing center-panned elements. While the three-band setup might seem limiting, the EQ's musical quality and ability to enhance both bass and treble are undeniable. However, its quirky control operations and the three-band constraint mirror the original design's quirks. Yet, at its price, the RS56 is a compelling choice for those seeking a vintage EQ experience.

Waves RS56 review | MusicRadar

A hard-hitting alternative to typical Pultec emulations, Waves' RS56 Passive EQ impresses with its four peak shapes and enhanced gain. The plugin faithfully replicates the original hardware while adding modern features like an EQ graph and peak/VU metering. However, its limited frequency selection might frustrate users seeking more flexibility. Though it can sound harsh at sharp Q settings, its ability to deliver smooth and musical results makes it a versatile studio tool, despite its frequency constraints.

Mentioned in this article from the official Waves website.

I used to do this mixing with the Aphex Aural Exciter hardware, and it works just as well with the plugin. I set the toms using the RS56 Passive EQ or some other EQ with a ton of mids and lows and not too much top. I then use the Aphex Vintage Aural Exciter as I would with parallel compression, but as a parallel EQ. Using an aux track I set the Aphex Exciter for the clarity and punch that I want, and I slide it in to taste. This works better than adding it to the toms directly (as an insert) – try it and you'll see what I mean. It adds all that a drummer would love, without killing the mix when the thunder happens. Thanks to Waves for making this plugin sound and act like the hardware!
