SUS4 Lume 2A

Opto-style levelling with a slow, musical release that never sounds like it’s working.

Included in the SUS4 plugin bundle. One licence, every plugin, every update.

Opto-style levelling with a slow, musical release that never sounds like it’s working. The smooth, hands-off way to ride a vocal or bass to a steady front.

Light-dependent gain reduction that leans into the material instead of clamping it.
