The fairchild added a lot more colour and grit than the LA-2A which suited the RATM heavy rock style. This also reduced noticable pumping and breathing from the gain reduction. I felt that running the drum bus compression in parallel added more weight to the drums and made them hit harder.

The playlist containing the comparison can be found here: Following the same pattern as the previous tests, the plugins used were the Waves PuigChild 670, UAD Fairchild 670 Legacy and the UAD Fairchild 670 Collection. This method avoids the audible pumping and breathing from slamming the signal, and reinforces the uncompressed signal by pulling up the quieter decay and reverb of drums.Īll three revisions of the Fairchild 670 are set up with the fastest time constant (1) and a high input gain to colour the audio.

This approach uses heavy compression with Fairchild 670 emulations running in parallel to blend in the compressed signal. Check Thomann Pros + Classic valve tones and colours. The final dynamic processing test I conducted was an alternative approach to drum bus compression. published 21 February 2014 MusicRadar Verdict A marked improvement over the already impressive original UAD Fairchild emulation, this dynamic duo hits the spot.
