Built around Rupert Neve's custom transformers, the 543 delivers a combination of warmth, flexibility, and precision for diverse sources. With the compressor disengaged, the 543 functions as a high-quality, transformer-coupled line amplifier; two units can be linked for stereo operation. The enclosure adheres to standard 500-series specifications, with power and I\/O supplied via the rack.\u003cbr\u003e\u003cbr\u003e\n\u003c\/div\u003e\u003cdiv\u003eAt its core is a highly accurate, low-noise VCA with no inherent tonal character, where a portion of the audio signal is rectified and smoothed into a control voltage. The speed and precision of this response (attack and release) largely determine how the compressor sounds, and can be fully adjusted to taste on the 543.\u003cbr\u003e\u003cbr\u003e\n\u003c\/div\u003e\u003ch2\u003eFeatures\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eThreshold: -30dB to +20dB\u003c\/li\u003e\n\u003cli\u003eRatio: 1.1:1 to 40:1 (limit)\u003c\/li\u003e\n\u003cli\u003eComp In: illuminated push-button, engages compressor\u003c\/li\u003e\n\u003cli\u003eF\/F + F\/B: switches between Feed Forward (more pumping, envelope-shaping) and Feed Back (smoother, more natural)\u003c\/li\u003e\n\u003cli\u003eMake-up gain: continuously variable, -6dB to +20dB\u003c\/li\u003e\n\u003cli\u003eAttack: continuously variable, 20ms to 75ms\u003c\/li\u003e\n\u003cli\u003eRelease: continuously variable, 100ms to 2.5s\u003c\/li\u003e\n\u003cli\u003eRMS\/Peak: switches between RMS detection (perceived loudness) and Peak detection (direct waveform, prevents clipping)\u003c\/li\u003e\n\u003cli\u003eS\/C HPF: switchable highpass filter on the sidechain, fixed at 250Hz, affects only the compression signal, not the main output\u003c\/li\u003e\n\u003cli\u003eLink: links gain reduction circuits for stereo operation\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Rupert Neve Designs","offers":[{"title":"Default Title","offer_id":53344932102411,"sku":"TT-WRP543","price":1099.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0760\/6327\/7323\/files\/01_fc14d723-a49f-480c-b698-71b9feca1210.jpg?v=1788720983","url":"https:\/\/dbmusicstore.nl\/en\/products\/rupert-neve-designs-543-mono-compressor-limiter-compressor","provider":"Dbmusicstore Utrecht","version":"1.0","type":"link"}
