Rupert Neve Designs RND-545 500 Series Source Enhancer

The Rupert Neve Designs 545 Primary Source Enhancer is a single-channel 500 Series module purpose-built to solve one of live sound's most persistent problems: microphone bleed and feedback. Rather than using traditional gating or EQ-based feedback suppression, the 545 employs an intelligent analog circuit that continuously distinguishes between the intended primary source and unwanted background noise. This allows it to reduce ambient bleed and increase gain before feedback by up to 20dB, giving engineers significantly more headroom to work with on stage.

Designed by legendary audio engineer Rupert Neve, the 545 processes the signal entirely in the analog domain, meaning there is no digital conversion latency or processing artifacts. This makes it equally suited for critical studio tracking sessions where isolation between microphones is essential. The module fits any standard API 500 Series compatible chassis and occupies a single slot, making it straightforward to add to existing racks. With its focused feature set and transparent operation, the 545 is a specialized tool that does one job exceptionally well — keeping your primary source clean and clear in challenging acoustic environments.
