The Rupert Neve 543 Mono Compressor delivers the discrete, musical-sounding compression and limiting made famous in the Portico 5043 to 500 series.
The 543 features a fully controllable compressor limiter with feed-forward/feedback modes, Peak/RMS detection and a built-in side chain highpass filter.
