The structure is based on the typical vari-mu solution. Apart from the classic INPUT, THRESHOLD and OUTPUT controls it introduces switchable high pass filter in the sidechain, parallel compression (MIX knob), independent ATTACK and RELEASE switches and user replaceable tubes accessible from the back of the unit.\u003c\/p\u003e\u003cp\u003eThe Tubecore was designed as a studio mastering compressor. It is built using the 3U enclosure, which improves front panel clarity and makes it easier to replace tubes located at the back. The compressor allows you to work either in dual mono or mid\/side mode (M\/S). The Mode switch has two bypass positions – they both do the same, but IGS has added the second one for your comfort and quick A\/B comparing.\u003c\/p\u003e\u003cp\u003eThe design of the Tubecore 3U is based on the ease of tube replacement. As a user, you can choose between a few types: 6N1P-EW – standard set of tubes, \"standard\" IGS compression, 6BC8\/6BZ8 – tight, transparent, punchy compression, 6386 – legendary compression, by famous twin triode, 5670 – deep and dark tube compression. The User Manual describes in detail how to replace tubes, so it is quick and straightforward.\u003c\/p\u003e\u003cp\u003eEvery single Tubecore 3U is hand made with high quality, matched components (1% metal film resistors, Wima caps). It is equipped with 6N1P-EW NOS tubes and individually calibrated to give you the unique and unspoiled experience of one of the best vari-mu compressors in history. It is equipped with Carnhill and Sowter audio transformers.\u003c\/p\u003e\u003ch3 style=\"margin: 1em 0px; padding: 0px;\"\u003eSpecifications:\u003c\/h3\u003e\u003cul style=\"margin: 1em 0px; padding: 0px 0px 0px 40px; list-style-position: initial; list-style-image: initial;\"\u003e\n\u003cli style=\"margin: 0px; padding: 0px;\"\u003eVari-mu Compressor\u003c\/li\u003e\n\u003cli style=\"margin: 0px; padding: 0px;\"\u003eAll stepped manipulators: 24 pole Elma switches\u003c\/li\u003e\n\u003cli style=\"margin: 0px; padding: 0px;\"\u003eSidechain HPF: 120Hz, 60Hz, Off\u003c\/li\u003e\n\u003cli style=\"margin: 0px; padding: 0px;\"\u003eWET\/DRY mixer: 0 - 100%, 4 dB step\u003c\/li\u003e\n\u003cli style=\"margin: 0px; padding: 0px;\"\u003eMID\/SIDE processing: OpAmp M-S encode\/decode\u003c\/li\u003e\n\u003cli style=\"margin: 0px; padding: 0px;\"\u003eInput Impedance (balanced): XLR, 600 Ohm, Carnhill balanced\u003c\/li\u003e\n\u003cli style=\"margin: 0px; padding: 0px;\"\u003eOutput Impedance (balanced): XLR, 600 Ohm, Sowter balanced\u003c\/li\u003e\n\u003cli style=\"margin: 0px; padding: 0px;\"\u003eOperating level: +4dBu\u003c\/li\u003e\n\u003cli style=\"margin: 0px; padding: 0px;\"\u003eMax input level: +22 dBu\u003c\/li\u003e\n\u003cli style=\"margin: 0px; padding: 0px;\"\u003eMax output level: +22 dBu\u003c\/li\u003e\n\u003cli style=\"margin: 0px; padding: 0px;\"\u003eDynamic Range: \u0026gt;107 dBA (@ 1kHz, +24 dBu)\u003c\/li\u003e\n\u003cli style=\"margin: 0px; padding: 0px;\"\u003eMax gain: +35dB\u003c\/li\u003e\n\u003cli style=\"margin: 0px; padding: 0px;\"\u003eMax gain reduction: 20 dB\u003c\/li\u003e\n\u003cli style=\"margin: 0px; padding: 0px;\"\u003eAttack: 0.1 - 30ms\u003c\/li\u003e\n\u003cli style=\"margin: 0px; padding: 0px;\"\u003eRelease: 0.1 - 4s\u003c\/li\u003e\n\u003cli style=\"margin: 0px; padding: 0px;\"\u003eFrequency response : 20Hz to 20kHz; +\/- 0.2dB\u003c\/li\u003e\n\u003cli style=\"margin: 0px; padding: 0px;\"\u003eSignal to Noise Ratio: 87 dBA\u003c\/li\u003e\n\u003cli style=\"margin: 0px; padding: 0px;\"\u003eTHD: 0.12 %\u003c\/li\u003e\n\u003cli style=\"margin: 0px; padding: 0px;\"\u003eTHD+N: 0.15 %\u003c\/li\u003e\n\u003cli style=\"margin: 0px; padding: 0px;\"\u003eIMD (SMPTE): 0.32%\u003c\/li\u003e\n\u003cli style=\"margin: 0px; padding: 0px;\"\u003eCrosstalk: 82 dB\u003c\/li\u003e\n\u003cli style=\"margin: 0px; padding: 0px;\"\u003eVoltage: 115\/230V AC, 50-60Hz\u003c\/li\u003e\n\u003cli style=\"margin: 0px; padding: 0px;\"\u003ePower consumption: 44W\u003c\/li\u003e\n\u003cli style=\"margin: 0px; padding: 0px;\"\u003ePower supply: external\u003c\/li\u003e\n\u003cli style=\"margin: 0px; padding: 0px;\"\u003eTube set: 6N1P-EW, 6BC8, 5670, 6386\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IGS Audio","offers":[{"title":"Default Title","offer_id":44450881601639,"sku":"175477","price":2195.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/igs-audio-tubecore-mastering-compressor-387-used_175477_1_214867a6-0319-4afd-8bef-d6f5135935e1.jpg?v=1787094938","url":"https:\/\/vintageking.mom\/products\/igs-audio-tubecore-mastering-compressor-387-used","provider":"Vintage King","version":"1.0","type":"link"}
