{"product_id":"igs-audio-tubecore-mastering-varimu-compressor","title":"IGS Audio Tubecore Mastering Vari-Mu Compressor","description":"\u003cp\u003eThe \u003cstrong\u003eIGS Audio Tubecore 3U\u003c\/strong\u003e is a fully symmetric transformer balanced stereo mastering compressor. 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\u003eSpecifications:\u003c\/h3\u003e  \u003cul\u003e \u003cli\u003eVari-mu Compressor\u003c\/li\u003e \u003cli\u003eAll stepped manipulators: 24 pole Elma switches\u003c\/li\u003e \u003cli\u003eSidechain HPF: 120Hz, 60Hz, Off\u003c\/li\u003e \u003cli\u003eWET\/DRY mixer: 0 - 100%, 4 dB step\u003c\/li\u003e \u003cli\u003eMID\/SIDE processing: OpAmp M-S encode\/decode\u003c\/li\u003e \u003cli\u003eInput Impedance (balanced): XLR, 600 Ohm, Carnhill balanced\u003c\/li\u003e \u003cli\u003eOutput Impedance (balanced): XLR, 600 Ohm, Sowter balanced\u003c\/li\u003e \u003cli\u003eOperating level: +4dBu\u003c\/li\u003e \u003cli\u003eMax input level: +22 dBu\u003c\/li\u003e \u003cli\u003eMax output level: +22 dBu\u003c\/li\u003e \u003cli\u003eDynamic Range: \u0026gt;107 dBA (@ 1kHz, +24 dBu)\u003c\/li\u003e \u003cli\u003eMax gain: +35dB\u003c\/li\u003e \u003cli\u003eMax gain reduction: 20 dB\u003c\/li\u003e \u003cli\u003eAttack: 0.1 - 30ms\u003c\/li\u003e \u003cli\u003eRelease: 0.1 - 4s\u003c\/li\u003e \u003cli\u003eFrequency response : 20Hz to 20kHz; +\/- 0.2dB\u003c\/li\u003e \u003cli\u003eSignal to Noise Ratio: 87 dBA\u003c\/li\u003e \u003cli\u003eTHD: 0.12 %\u003c\/li\u003e \u003cli\u003eTHD+N: 0.15 %\u003c\/li\u003e \u003cli\u003eIMD (SMPTE): 0.32%\u003c\/li\u003e \u003cli\u003eCrosstalk: 82 dB\u003c\/li\u003e \u003cli\u003eVoltage: 115\/230V AC, 50-60Hz\u003c\/li\u003e \u003cli\u003ePower consumption: 44W\u003c\/li\u003e \u003cli\u003ePower supply: external\u003c\/li\u003e \u003cli\u003eTube set: 6N1P-EW, 6BC8, 5670, 6386\u003c\/li\u003e \u003c\/ul\u003e","brand":"IGS Audio","offers":[{"title":"Default Title","offer_id":44449849180263,"sku":"55382","price":3408.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/igs-audio-tubecore-vari-mu-compressor-1_d9f76fab-1336-4907-bccc-5ab4a802edaf.jpg?v=1787090683","url":"https:\/\/vintageking.com\/products\/igs-audio-tubecore-mastering-varimu-compressor","provider":"Vintage King","version":"1.0","type":"link"}
