Rupert Neve Designs Portico 545
- LED indicates power status
- Illuminated push-button that engages the Primary Source Enhancer’s effect
- LED shows when the 545 is actively processing signal (i.e., when the input signal exceeds the threshold)
- Adjusts the dBu level at which the enhancement engages
- Controls the maximum attenuation applied after the signal drops below the threshold, adjustable from 0dB to -20dB
- Selects between two time constants, offering either a slower or faster attack/release for various source dynamics
- Switches between RMS and Peak detection modes for precise transient control and creative dynamic shaping
Product information "Rupert Neve Designs Portico 545"
Based on the renowned Portico 5045 circuitry – trusted on countless tours, stages, and broadcast environments – the Rupert Neve Designs 545 Primary Source Enhancer provides outstanding feedback reduction without compromising the natural sound of the source. Unlike traditional noise gates, the 545 operates on an intelligent analog principle, sensing when a performer is active or silent and adjusting gain smoothly. With Rupert Neve’s custom input and output transformers and pure analog signal path, the 545 ensures superior control, clarity, and musical integrity — making it the most natural-sounding and effective feedback suppression tool on the market.
