Mix Bus Compression: Settings That Work

By Sarah Okonkwo ·

Purpose of Mix Bus Compression

Mix bus compression glues tracks together, adding cohesion and energy. It is about unity, not loudness.

Starting Settings

Compressor Types

VCA (SSL-style)

Clean, transparent. SSL G-Bus is the standard. Great for pop, rock, electronic.

Vari-Mu (Fairchild/Manley)

Warm, musical, adds color. Ideal for jazz, folk, singer-songwriter.

Optical (LA-2A style)

Smooth, natural, program-dependent. Best for ballads and acoustic music.

Common Mistakes

Too much ratio (4:1+) squashes dynamics. Too fast attack kills transients. More than 3-4dB reduction causes pumping.

Parallel Compression

Blend heavily compressed signal with dry mix. Preserves transients while adding body. Use 10-20% wet blend.
