How to Apply 2 Buss Compression to a Mix

I am a major proponent of 2-buss compression. I tend to apply it at varying degrees depending upon the dynamics of the song. I enjoy shaping the overall sound of the mix as a whole. 2-buss compression provides greater flexibility when using this method.



I will show you how to apply 2-buss compression to your mix, using a reproduction of the SSL G384 Buss Compressor as an example.

Things You'll Need

• Stereo Buss Compressor
• Recorded music
• DAW

Instructions

1. I tend to apply 2-buss compression from the onset of the mix and it typically remains there throughout.

   The only things that are usually adjusted are the input/output gain.

   Adjusting the attack and release times at the final stages of the mix will alter it beyond the initial intent,
   and thus totally change the character of the mix.

2. For most music I like to use a compression ratio of 2:1. This assists in gluing the mix together to feel like a unified whole. These days, when mixing exclusively within ProTools, the mix may need some help to sound less like it's comprised of separate elements.

3. I typically gravitate towards a slower attack setting of 10-30:1. This allows the compressor to respond less to the initial transient and allow the music to retain punch and definition.

   The release setting is equally important. I begin with it set to Auto Release, though if I feel that I need even more punch or that I need the drums to open up a bit more I will move it to maybe .3ms.

4. I adjust the input gain in accordance with how aggressive I want the compression to be. A general starting point would be to allow for it to reduce the gain by 2db. Though it can be very musical reducing the material by up to 6db.
