Rupert Neve Designs 5045 Primary Source Enhancer

A Modern Classic from Rupert Neve Designs

Derived from Rupert Neve Designs expertise, the 5045 takes a different approach than traditional noise gates. Rather than abruptly "cutting" the signal, it intelligently reduces gain when the source is inactive. The result: more gain before feedback and improved intelligibility, while preserving the source's timbre and dynamics.

Designed for Demanding Live Sound and Vocal Capture

The 5045 is aimed at stage managers, front-of-house/monitor engineers, and venues with high reverberation where feedback is a concern. On a lead vocal, ambient microphone, or conference podium, it allows speech to pass through and "closes" cleanly between phrases, enabling higher monitor and system levels without excessive risk.

Features Designed for Efficiency in the Field

Setup is straightforward: insert the 5045 at line level (microphone preamp output or console insert loop), engage the processing, and adjust the "Threshold" so the "Process Active" LED follows the voice. Adjust "Depth" to control attenuation between phrases, then select the time constant from A to F to balance responsiveness and naturalness according to the acoustics and performance style.

The "RMS/Peak" selector refines detection: in "Peak" mode, the return to nominal level is very fast, useful for preserving word attacks or for creative uses on instruments. In "RMS" mode, the reaction is smoother and perceived as more "musical," perfect for vocals.
