Stepped controls solve that from the workflow side, because every decision is a position you can note and step back from, instead of hunting for the previous setting from scratch. The MS modification splits sum and difference before the gain stage, so you press on centre or sides separately, and repeatable settings let you compare both versions calmly. This is the combination for a record where every track has to hold the same character.\u003c\/p\u003e\n\n\u003ch3\u003eThe valve itself as the gain control\u003c\/h3\u003e\n\u003cp\u003eA variable mu circuit has neither a VCA nor an optical cell. Gain changes through the bias voltage of remote cutoff valves, so the reduction is not applied to the signal, it is how the amplifying stage behaves. That produces the characteristic response: the harder you push it, the gentler the curve looks, instead of a hard knee at the threshold. The mode switch gives 1.5:1 in Compress and 4:1 to 20:1 in Limit, attack is continuously variable from 25 to 70 ms, and recovery has five settings: 0.2 s, 0.4 s, 0.6 s, 4 s and 8 s. A high pass filter in the sidechain at -3 dB @ 100 Hz keeps the low end out of the detector so the kick does not drive the whole mix.\u003c\/p\u003e\n\n\u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMastering version with stepped Grayhill switches\u003c\/li\u003e\n\u003cli\u003eMS modification with mid-side encoding and decoding\u003c\/li\u003e\n\u003cli\u003eRepeatable settings across a whole album\u003c\/li\u003e\n\u003cli\u003eTwo channel compressor and limiter with an all-valve path\u003c\/li\u003e\n\u003cli\u003eCompress mode at 1.5:1 and Limit mode from 4:1 to 20:1\u003c\/li\u003e\n\u003cli\u003eAttack continuously variable from 25 to 70 ms\u003c\/li\u003e\n\u003cli\u003eRecovery in five steps: 0.2 s, 0.4 s, 0.6 s, 4 s and 8 s\u003c\/li\u003e\n\u003cli\u003eHigh pass filter in the sidechain at -3 dB @ 100 Hz\u003c\/li\u003e\n\u003cli\u003eManley IRON transformers with nickel laminations\u003c\/li\u003e\n\u003cli\u003eChannel linking for stereo operation\u003c\/li\u003e\n\u003cli\u003eHardwire bypass for comparison against the unprocessed signal\u003c\/li\u003e\n\u003cli\u003eIlluminated Sifam gain reduction meters\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eVariable gain valves: 5670 x2 in the standard version\u003c\/li\u003e\n\u003cli\u003eAmplifying valves: 5751 or 12AX7 x2\u003c\/li\u003e\n\u003cli\u003eOutput valves: 12BH7 x2\u003c\/li\u003e\n\u003cli\u003eSidechain rectifier: 12AL5 x2\u003c\/li\u003e\n\u003cli\u003eFrequency response: 20 Hz to 25 kHz (±0.1 dB)\u003c\/li\u003e\n\u003cli\u003eMaximum gain: 35 dB\u003c\/li\u003e\n\u003cli\u003eMaximum output: +30 dBu with 26 dB of headroom\u003c\/li\u003e\n\u003cli\u003eTHD: below 0.1% at 1 kHz\u003c\/li\u003e\n\u003cli\u003eNoise floor: -85 dB typical\u003c\/li\u003e\n\u003cli\u003eBalanced inputs and outputs, 600 Ohm\u003c\/li\u003e\n\u003cli\u003eControls: stepped Grayhill switches with 1% metal film resistors\u003c\/li\u003e\n\u003cli\u003eDimensions: 19 x 3.5 x 10 inches, 2U; power consumption 80 W\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Manley","offers":[{"title":"Default Title","offer_id":58444341936460,"sku":"14903","price":7599.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0769\/9854\/1644\/files\/ManleyStereoVariableMuLimiter_Compressor1_3ffd9921-f6b0-4ff5-8f12-998d9a06e5de.jpg?v=1786977911","url":"https:\/\/noiseroom.lt\/products\/manley-stereo-variable-mu-mastering-version-with-ms-mod-option","provider":"Noise Room","version":"1.0","type":"link"}
