Rupert Neve Designs 545 Primary Source Enhancer

For live sound engineers, feedback is public enemy number one. Based on the circuitry in Rupert Neve Designs Portico 5045, the 545 Primary Source Enhancer is a monaural 500 Series module that functions similarly to a noise gate but operates on a different principle. With its superior background bleed attenuation and feedback suppression, the 5045 has become a mainstay in countless tour racks, arenas, houses of worship, and broadcast studios — largely replacing noise gates in live applications where noise and feedback suppression is mission critical. Now the 545 offers the same natural-sounding performance and reliability in the convenient 500 Series format. Amazingly effective at reducing feedback without degrading the sonic integrity of the source, the 545 effectively increases the level of a live mic signal by up to 20dB before the onset of feedback. With its minimalist control set, the 545’s ease of use permits quick on-the-fly adjustments during performances and also makes it a good choice even for unattended, set-it-and-forget-it scenarios.
