The Passive-Active Pack is a collection of three very different equalizers, each with its own character and quirks. Together they make an excellent secret-weapon analog-style EQ toolbox.

The Passive and Active equalizers emulate real workhorse units, used on thousands of recordings from past to present. The Focusing Equalizer, an original creation of Softube's, combines these with analog saturation and a novel workflow, to give you musical results, and a wonderful sound every time.

Timeless equalizers revitalized.

Fat, tube-driven, passive equalizers can be so much more than functional tools. They impart character and style to any source; drums, synths, vocals, guitars, strings, brass… you name it! As such, they’ve been sought after in top-of-the-line international studios for decades, and their sound enriches the textures of thousands of classic records, in every genre you can imagine.

A powerful and musical modern plug-in channel strip with the unique vintage sound of Chandler Limited®, the Zener-Bender combines the crisp and colorful character of the Curve Bender Mastering Equalizer with the big, punchy Zener Limiter to bring class, history, and most crucially of all, a phenomenal sonic impact. Component-modeled with Softube's customary care and experience, these units together can take charge of any mix.

A secret weapon from the 60s.

Meticulously modeled by Softube, the RS127 Rack, RS127 Box, and RS135 deliver the sweetest treble equalization imaginable – the sound of real passive analog circuitry in all its glory.

With the Brilliance Pack, today's DAW-based mix engineers can add all the air and sparkle they want, without the slightest trace of harshness – just like the world's top engineers at Abbey Road Studios, London, have done on their recordings from the 1960s onwards.
