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.

Vertical\/Lateral or Sum\/Difference) to the Variable Mu® Limiter Compressor which opens the door to stereo encoding and decoding as well as exciting image enhancement processing capabilities. For instance, setting to compress only the in-phase information allows the augmentation of the stereo image as the out-of-phase content is left untouched. Or, conversely, if you need a more-mono mix for broadcast, or vinyl-cutting for instance, you can set it to kill off more of the out-of-phase info which leaves more in-phase material in the final result. In order to add both M-S and the HP SC mods, Manley's techs move the power switch to the rear panel and install both channels' HP SC switch to the center hole where the power switch was. The M-S switches then flank this switch.\u003c\/p\u003e \u003cp\u003eAfter about 6dB of limiting, the 5670 version of this compressor tends to sound more squashed than the original 6386 version. Some like it better, some don't-- depends on what you're trying to do. To solve all these problems, Manley came up with a really good solution: the \u003cstrong\u003eT-Bar Mod\u003c\/strong\u003e which uses a pair of 6BA6 pentodes wired as single triodes to replace each dual triode 5670 (or 6386). the 6BA6 TBAR Mod is the preferred system to use in the Manley Variable Mu® for reasons of ability to perfectly match each phase-halve section and each stereo set, ability to select for lo-noise and lo-microphonic sets for a low cost, and because the action of the 6BA6's so closely resemble the smooth 6386 limiting curves.\u003c\/p\u003e","brand":"Manley","offers":[{"title":"Default Title","offer_id":48411832276,"sku":"441621","price":5130.0,"currency_code":"INR","in_stock":true}],"url":"https:\/\/sg-2111.myshopify.com\/products\/manley-stereo-variable-mu-vacuum-tube-limiter-compressor-the-works-options","provider":"SG_2111","version":"1.0","type":"link"}
