Experience fully tube-based Vari-Mu Fairchild compression with the Heritage Audio Herchild Model 670, a faithful reproduction of the original with a few key additions to make it more practical for modern-day studio use. The Model 670 features 22 tubes and 9 transformers to bring warmth and punch to your tracks or mixes and ensure the absolute highest quality possible. This two-channel compressor offers four modes of operation. Either use each channel separately or linked together (stereo). The LAT/VERT and LAT/VERT Link modes make mid/side processing possible.
While remaining true to the original in terms of response and sound, the Model 670 offers new features for today's production workflow including direct access to the continuously variable slope control (DC Threshold) and side-chain filter (SC Filter).
- A faithful reproduction, the original Herchild Model 670 is packed with 22 tubes and 9 transformers. It operates at a high voltage and uses only the best components to deliver the utmost quality possible.
- This is immediately recognized during use as there are no audible thumps produced. And with extremely low distortion and noise, this compressor is perfect for mixing and mastering duties.
- The 6 attack and release times have been exactly duplicated like those of its all-tube side-chain circuit, for precise control.
- A clean, transparent sound is possible with no artefacts or pumping. You can also create a more noticeable, heavier, and denser effect with extra harmonics if pushed harder.
- LAT/VERT Mode (the equivalent to mid/side) gives you separate control over the center and side signals of a stereo track separately to make your songs sound wider, deeper, and more focused.
- LAT/VERT Link mode also for mid/side processing, but this time with the two channels linked together and controlled by taking the average settings on both channels to determine what the overall control will be.
- There is now access to the progressive ratio (DC Threshold), which is a unique curve adjustment combining control of the ratio and the knee. This is continually adjustable from hard limiting to very smooth and transparent compression.
- Side-chain filter with four different frequencies to choose from to precisely tailor your compression (50, 100, 200, 350 Hz, and Off).
