In the Massive Passive, the \"Gain\" and \"Bandwidth\" controls do interact (on purpose). When you change the \"Bandwidth\" the step size must and will change.\u003c\/p\u003e  \u003cp\u003eOn the regular version, you get a full 20 dB boost or cut only when: the bandwidth is fully clockwise (narrow) in bell mode or fully counter-clockwise in shelf mode. Here on the Mastering Version, this maximum boost or cut is 11dB. Conversely at the widest bell, the maximum boost or cut is 6dB and the narrowest shelf maxes out at 12 dB. A similar situation is also true for the bandwidth detents. So in this new Mastering Version, do not expect a certain dB change per step as it will vary according to where the bandwidth is set. But whatever the step sizes are, they will be repeatably 16 steps.\u003c\/p\u003e  \u003cp\u003eThe Frequency select is already detented as it is and always has been a Grayhill switch. It also interacts in shelf mode. On a similar note, the Massive Passive is a \"parallel design\" and not the conventional \"series design.\"  This means the bands interact with each other too. It is possible, to set a band to boost 20 dB but if another band is boosting near or at that frequency, very little will happen. On a conventional EQ the two bands \"add\" and you would be boosting 40 dB into clipping. Because the bands interact, predictable step sizes are unrealistic, however, with the Mastering Version, you will be able to repeat settings (if you log them of course). The price paid for interacting bands, is a better sounding EQ and bizarre looking settings (on purpose). Unlike virtually every other EQ, the Massive Passive allows much more EQ without sounding \"processed.\" Where 5 or 6 dB is about all one could attempt with other EQs in mastering, the Massivo amazes engineers with how much EQ they can do and get more \"natural\" results at the same time. We could have squeezed 11 position Grayhill switches in the modules if we had wanted 1\/2 dB steps but then the maximum range would have become only 5.5 dB.\u003c\/p\u003e  \u003cp\u003eRemembering what we stated above, the minimum range would then become about 1.5 dB with approximately 0.2 dB steps. This approach would have essentially thrown away most of the useful range the unit is capable of. Going with these special mechanically detented knobs which use the same pots underneath that the normal Massivo uses, we get nearly all the range of the normal version, but with the repeatability of the detents. We have also custom tailored the Filters in the Mastering Version specifically for Mastering purposes, moving them lower and higher than the normal version, with mastering engineers specifically in mind. If you are looking for drastic effects (like telephone sounds) then get the normal version. These filters are really geared for mastering engineers. Additionally, the Master Gain Trim controls in the Mastering Version are true 11 position 1\/2 dB stepped Grayhill switches set up for a range between -2.5 to +2.5 dB of master gain trim. This allows more confidence in left\/right matching and calibration.\u003c\/p\u003e    \u003ch3 id=\"toc_1\"\u003eSPECIFICATIONS:\u003c\/h3\u003e  \u003cul\u003e \u003cli\u003eIns \u0026amp; Outs Balanced XLR \u0026amp; 1\/4\" (accepts unbalanced)\u003c\/li\u003e \u003cli\u003eLevel +4 dBu nominal, internal switches for -10 operation\u003c\/li\u003e \u003cli\u003eHARDWIRE Bypass Switch (unit does pass audio when powered off)\u003c\/li\u003e \u003cli\u003e44 Frequencies (roughly 1\/4 octave spacing)\u003c\/li\u003e \u003cli\u003eFrequency Range: 22 Hz to 27 kHz\u003c\/li\u003e \u003cli\u003eEQ Boost\/Cut Range: Maximum 11 dB boost or cut\u003c\/li\u003e \u003cli\u003eNominal Q range: 1.5 to 3 (uniquely active in shelf modes)\u003c\/li\u003e \u003cli\u003eFrequency Response: ±2 dB: 8 Hz to 60 kHz\u003c\/li\u003e \u003cli\u003eMaximum Output @ 1.5% THD +37 dBv; +26 dBv @ 20 Hz\u003c\/li\u003e \u003cli\u003eTHD \u0026amp; Noise (1 kHz @ +4 dBu): 0.06%\u003c\/li\u003e \u003cli\u003eNoise Floor (referred to +4 dBu): -85 dB (A Weight)\u003c\/li\u003e \u003cli\u003eDynamic Range: 120 dB\u003c\/li\u003e \u003cli\u003eTube Complement: 2 x 12AU7, 4 x 6414\u003c\/li\u003e \u003cli\u003ePower Consumption (120\/240VAC): 72 watts\u003c\/li\u003e \u003cli\u003eUnit is factory set for 100 V, 120 V or 220-240 VAC operation for original destination country's mains voltage\u003c\/li\u003e \u003cli\u003eOperating Mains Voltage changeable with power transformer changeover switch and fuse value change\u003c\/li\u003e \u003cli\u003eMains Voltage Frequency: 50~ 60Hz\u003c\/li\u003e \u003cli\u003eSize (3U): 19\" x 5.25\" x 10\"\u003c\/li\u003e \u003cli\u003eWeight: Unit 21 lbs\u003c\/li\u003e \u003cli\u003eShipping Weight: 27 lb\u003c\/li\u003e \u003c\/ul\u003e","brand":"Manley Labs","offers":[{"title":"Default Title","offer_id":44451183984743,"sku":"458927","price":5295.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/manley-massive-passive-tube-equalizer-mastering-version-mmmsmp373-used_458927_1.jpg?v=1787096178","url":"https:\/\/vintageking.com\/products\/manley-massive-passive-tube-equalizer-mastering-version-mmmsmp373-used","provider":"Vintage King","version":"1.0","type":"link"}
