Waves Primary Source Expander

About Waves Primary Source Expander

The Waves Primary Source Expander (PSE) is a precision expander plugin designed to reduce stage bleed and sensitivity to feedback when microphones are idle, making it ideal for live sound and mixing live recordings.

• Reduces stage bleed and sensitivity to feedback when mics are idle
• Smoothly attenuates levels when the source drops below the defined threshold
• User-friendly GUI for quick operation – set and forget
• Internal and external sidechain with high-pass/low-pass filters
• Ducking mode for added precision in complex live scenarios
• Release time presets

Whether mixing front-of-house or monitors in a live venue, or working on a live recording in the studio, PSE ensures that mics are as loud and clean as possible while preserving the source’s original tone and the natural ambience of the location.
