HERCHILD Next Gen Model 670N: The Fairchild Sound Reborn for Modern Studios

For decades, the legendary Fairchild compressors have shaped the sound of the world’s biggest hit records. Now, Heritage Audio brings that iconic tone into the modern age with the HERCHILD Next Gen Model 670N – a powerful, accessible, and feature-rich evolution of Vari-Mu tube compression.

A Legacy Only Heritage Audio Could Build

Heritage Audio spent years perfecting their Fairchild recreations, first with the HERCHILD 660/670 and later with the groundbreaking GRANDCHILD 670/500. These projects paved the way for the 670N – combining authentic Fairchild circuitry, NOS tubes, and custom transformers with fresh innovations for today’s productions. The result is a compressor that stays true to its roots while offering next-level flexibility.

Vintage Soul with Modern Capabilities

What sets the 670N apart is its thoughtful blend of classic tone and modern features. The unit offers independent bypass, advanced side-chain filtering, a progressive DC Threshold control, and a redesigned output gain stage built around the HA-880 transformer-coupled op-amp. These additions deliver precision and adaptability while preserving the unmistakable warmth and musicality that define the HERCHILD sound.

Powered by NOS Tubes and Custom Transformers

At the heart of the 670N are four NOS 6BA6 tubes and six newly designed custom transformers – hand-tuned for depth, richness, and character. This powerful analog design infuses mixes with weight, presence, and life, delivering the smooth glue and airy openness engineers expect from top-tier Vari-Mu compression.
