The Rupert Neve 545 is an essential 500 Series tool for feedback suppression and reverb reduction without degrading your source signal. Based on the acclaimed Portico 5045 circuitry, the 545 brings world-class primary source enhancement to compact setups—perfect for live sound, houses of worship, broadcast stages, and studio environments where clean, natural sound is critical.
Key Features
-
Power Status LED – Confirms the unit is powered.
-
Process Engage Button – Activates the enhancement circuitry.
-
Process Active Indicator – Shows when the 545 is affecting the signal.
-
Depth Control – Adjusts attenuation amount once signal drops below threshold.
-
Fast Mode – Selects between two time constants for responsive performance.
-
RMS/Peak Detection – Switch between RMS for smooth response or Peak for precision.
-
All-Analog Design – No filtering or digital processing; maintains sonic integrity.
-
Transformer-Coupled I/O – Rupert Neve Designs’ custom transformers for warmth and transparency.
Why It’s Special
Unlike conventional noise gates, the 545 Primary Source Enhancer works transparently to reduce system feedback and reverb without altering your tone. It “listens” for the presence of a vocal or instrument, passing the signal cleanly when active and gently attenuating it when idle. This intuitive, musical approach makes the 545 perfect for engineers of any skill level and invaluable for live performances where feedback control can make or break a mix.
