Marcella Araica buses all her drum tracks together and uses a Neve 33609 compressor to add punch and presence, bringing the drums more forward in the mix.
She maintains a low ratio to preserve transients, aiming for a moderate 3-5dB of gain reduction. The attack is set fast, which, on this compressor, still allows for the transient to come through. The release is on the "a1" auto setting, ensuring a smooth response.
The goal is not to squash but to subtly enhance the drum bus.
