The project began as an experiment in 2011 and was field tested in selected studios before release. Added to the original compression signature is what tracking, mixing and mastering actually require: a sidechain filter, stereo linking, and continuously variable threshold, attack and release.\u003c\/p\u003e\n\u003ch3\u003eA dual threshold that controls ratio and saturation\u003c\/h3\u003e\n\u003cp\u003eThe Altec 436 gave no access to its ratio or to the point where the amplifier begins to saturate. Here a dual threshold control puts both in reach, with ratio variable between 1.5:1 and 5:1. The practical result is that one unit can gently thicken a stereo bus or push a single track to the edge of tube saturation, without a chain of separate processors. Attack is adjustable from 2 to 40 milliseconds and release from 200 milliseconds to 2 seconds, covering fast drum transients and the long decays of vocals and strings alike.\u003c\/p\u003e\n\u003ch3\u003eA sidechain filter that saves the stereo bus\u003c\/h3\u003e\n\u003cp\u003eOn a mix bus the lowest octave usually takes control of the compressor, so kick and bass drive gain reduction for the whole programme while vocals and the top audibly pump along with them. A switchable highpass filter in the detector path, with a 6 dB rolloff cornered at 90 or 250 Hz, reduces how much the bottom steers the circuit, so compression responds to the whole mix rather than to the rhythm section. Stereo linking meanwhile keeps gain reduction identical in both channels, which is the condition for a stable image. Distortion stays below 0.05% under the threshold and rises to roughly 1% at full-scale compression, so tone changes along with how hard you push.\u003c\/p\u003e\n\u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDual-channel tube compressor with a fully differential signal path\u003c\/li\u003e\n\u003cli\u003eDesign based on the British-modified Altec 436\u003c\/li\u003e\n\u003cli\u003eDual threshold control governing ratio and amplifier saturation\u003c\/li\u003e\n\u003cli\u003eContinuously variable input, output, attack, release and threshold\u003c\/li\u003e\n\u003cli\u003eSwitchable highpass sidechain filter at 90 or 250 Hz\u003c\/li\u003e\n\u003cli\u003eStereo linking alongside independent controls for both channels\u003c\/li\u003e\n\u003cli\u003eTransformer balanced inputs and outputs on XLR connectors\u003c\/li\u003e\n\u003cli\u003eIlluminated VU meters with front-panel zero controls\u003c\/li\u003e\n\u003cli\u003eInternal tube balancing facility\u003c\/li\u003e\n\u003cli\u003e120 or 240 volt operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eChannels: 2\u003c\/li\u003e\n\u003cli\u003eRatio: adjustable between 1.5:1 and 5:1\u003c\/li\u003e\n\u003cli\u003eUsable input level range: -20 to +20 dBu\u003c\/li\u003e\n\u003cli\u003eOutput level range: -30 to +18 dBu\u003c\/li\u003e\n\u003cli\u003eOutput clip level: +23 dBu at 1% distortion\u003c\/li\u003e\n\u003cli\u003eAttack time: 2 to 40 milliseconds\u003c\/li\u003e\n\u003cli\u003eRelease time: 200 milliseconds to 2 seconds\u003c\/li\u003e\n\u003cli\u003eSidechain filter: 6 dB detector rolloff, switchable 90 or 250 Hz\u003c\/li\u003e\n\u003cli\u003eDistortion: below 0.05% under threshold, approx. 1% at full-scale compression\u003c\/li\u003e\n\u003cli\u003eFrequency response: 20-20,000 Hz, +\/- 0.5 dB\u003c\/li\u003e\n\u003cli\u003eDimensions: 2U, 9.5 inch depth, weight 10 kg\u003c\/li\u003e\n\u003cli\u003ePower: 120 or 240 VAC, 22 W, IEC inlet\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Retro Instruments","offers":[{"title":"Default Title","offer_id":54598554026321,"sku":"28582","price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/RetroInstrumentsRevolver1.jpg?v=1786975463","url":"https:\/\/wrdtunes.com\/products\/retro-instruments-revolver","provider":"Wired Tunes","version":"1.0","type":"link"}
