For these most demanding engineers in our industry, they have created specialized products such as the all-tube tape repro head amps, digital converters, high-powered vacuum tube monitor amplifiers, through to custom monitoring consoles, all the way up to complete facility design and installation. The \u003cstrong\u003eMastering Version\u003c\/strong\u003e of the Variable Mu® Limiter Compressor incorporating detented and logable steps built with 1% metal film resistors on sealed gold-contact Grayhill switches is available.\u003c\/p\u003e \u003cp\u003eThe MANLEY VARIABLE MU® LIMITER COMPRESSOR is one of the very few compressors that has become a real standard in Mastering studios and contributed to most hit records over the last decade and probably the next. Mu is tube-speak for gain, and Variable Mu® is Manley's registered trademark for this limiter compressor. It works by using the remote cut-off or re-biasing of a vacuum tube to achieve compression. \u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eMANLEY input \u0026amp; output transformers with nickel laminations in mu-metal cases with flat frequency response from 20Hz-25KHz\u003c\/li\u003e \u003cli\u003eBALANCED INPUTS \u0026amp; OUTPUTS (600 Ohms)\u003c\/li\u003e \u003cli\u003eFully differential ALL-TUBE circuitry using one each 5670, 5751, 7044 or 5687, \u0026amp; 12AL5 per channel\u003c\/li\u003e \u003cli\u003eIndependently regulated B+ and Heater supplies\u003c\/li\u003e \u003cli\u003eHard-wire BYPASS switch\u003c\/li\u003e \u003cli\u003eStepped switch INPUT attenuator as of 10\/2011.
