MASTERING MASSIVE PASSIVE®


Manley Massive Passive는 패시브 디자인이며 "True parametic"이 아닙니다. True parametic은 서로 상호작용하지 않는 컨트롤입니다. Massive Passive에서 "Gain" 및 "BANDWIDTH" 컨트롤은 상호 작용합니다. 우리는 1/2dB 단계를 일관적으로 설정하는 "GAIN" 스위치를 만들 수 없다. "BANDWITH"를 변경하면 스텝 사이즈 또한 변경되어야 합니다. 일반 버전에서는 대역폭이 벨 모드에서 시계 방향(좁음)이거나 선반 모드에서 시계 반대 방향으로 완전히 돌 때만 전체 20dB 부스트 또는 컷을 얻습니다. 마스터링 버전에서 이 최대 부스트 또는 컷은 11dB 입니다. 반대로 가장 넓은 벨에서 최대 부스트 또는 컷은 6dB이며 가장 좁은 선반에서 최대 값은 12dB입니다. 비슷한 상황은 대역폭 멈춤쇠에도 해당합니다. 따라서 이 새로운 마스터링 버전에서는 대역폭이 설정된 위치에 따라 달라지기 때문에 단계별로 dB 변경이 필요하지 않습니다. 그러나 스텝 사이즈가 무엇이든 관계 없이 16 스텝이 반복됩니다. FREQUENCY 선택은 항상 그레이 힐 스위치 였으므로 이미 중지되어 있습니다. 이것은 또한 선반모드로 상호 작용합니다.

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. Remembering 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. The slopes are all 18dB per octave on the mastering filters except for the highest 52kHz Low Pass filter which has a 30 dB/octave slope. If you are looking for drastic effects (like telephone sounds) then get the normal version. These filters are really geared for mastering engineers.

High Pass Filters: OFF, 12, 16, 23, 30, 39 Hz
Low Pass Filters: OFF, 52kHz, 40kHz, 27kHz, 20kHz, 15 kHz

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. The gain change voltage divider occurs before the final tube amplifier stag and after all of the passive EQ circuits.
