The H2 Audio 0011 Mic Pre & 3-Band EQ delivers that unmistakable Helios punch — open highs, tight lows, and lightning-fast attack — backed by massive headroom and creamy transformer warmth. Built like the originals, with refinements for today’s modern studio workflow.
 
Step into the control room from the golden era of rock & roll. The H2 Audio 0011 captures the exact tone and feel of the legendary Helios production modules that shaped countless ‘70s classic hits. Every note comes alive with transient snap, rich harmonic depth, and a musical EQ that shapes without smearing.
 
The Most Iconic Mic Pre from the 70’s Golden Era
From the Lustraphone M10 input transformer to custom-wound inductors and gold-plated ELMA switches, every part is engineered for the purest signal path. With 32V rails for massive headroom, the 0011 delivers pristine clarity when you want it and thick, saturated character when you push it.
 
This isn’t just a reissue. It’s Helios DNA, refined for the modern recording landscape.
 
Legendary Helios Tone, Modern Studio Ready
From vocals and drums to guitar and bass, the 0011 Mic Pre & 3-Band EQ gives you that unmistakable rock authority with the control you need for modern production.
