Both are based on passive circuits comprised of resistors, capacitors and inductors to sculpt tone;...

It is more like a Pultec in this regard. Maximum boost or cut is fully clockwise and can be up to 20 dB - but not necessarily.
  • Page 7: Designer's Notes

    NOTES 1) Do not assume the knob settings "mean" what you expect they should mean. Part of this is due to the interaction of the controls. Part is due to the new shelf slopes and part due to a lack of standards regarding shelf specification. 2) You may find yourself leaning towards shelf frequencies closer to the mids than you are used to and the "action"...
  • Page 8 More Mini-Ponderings from the Designer Clean versus colored - Active versus Passive - Tape versus Digital - well it all gets a bit tiresome. Here is the real deal: they are all a bit colored and for the most part remarkably clean. So if anything we are basing our preferences on which subtle flavor of color we either happen to like, or believe we need (based on something we read somewhere) which may be just a slightly familiar sound rather than some magnificient life changing event.
  • Page 9 Just a few notes for plug-in users. One question that gets asked a lot is “Why no ‘Link’ switch “or “Why not a stereo EQ with one set of controls?” Yeah, it would be sweet sometimes, especially if fewer knobs resulted in lower cost. The most accurate answer is “you guys are spoiled, ha ha”.
  • Page 10 "The Super-Pultec" The very earliest equalizers were very simple and primitive by Manley Labs has been building a few versions of the Pultec-style todays standards. Yes, simpler than the hi-fi "bass" and "treble" EQs for many years as well as an updated version of the EQ-500 controls we grew up with.

  • Page 12: Why Passive, Why Parallel

    Why Passive? And Why Parallel? If you hate tech talk, just skip this section - it has to do with The Massive Passive is a "parallel design" as opposed to the electronic parts and circuits and design philosophy. far more common "series design". A few pages back, we mentioned the main reason for going with a parallel design All EQs use capacitors.
  • Page 13: Phase Shift, Why Tubes

    Phase Shift? Mini Massive and Massive Passive - Similarities & Differences Deadly topic. This is probably the most misunderstood term floating The Mini Massive is obviously based on the lowest and highest about in the mixing community. Lots of people blame or name phase bands from the Massive Passive.
  • Page 14: Curves

    LOW SHELF CURVES Just like most EQs, a 100Hz low shelf doesn't reach "max" until about 10 Hz. Normal Shelf Wide Bandwidth (slope =about 4 to 5 dB/oct) Special Shelf Medium Bandwidth (slope = about 8 to 10 dB/oct) "Pultec Shelf" Narrow Bandwidth Bell Cut Narrow Bandwidth (just for reference) These 4 lowest frequency shelf curves are unique...

  • Page 17: Trims And The Gutz

    THE GUTS 1) To Open:There should be little or no reason to open the Mini Massive - No user servicable parts, no tubes to change and about the only reason to take the top off is unity gain adjustments. One can access the fuse on the back panel power connector without removing the top.
  • Page 18: Mains Voltage Setting

    AC MAINS VOLTAGE SELECTION This may involve soldering jumpers and cutting of printed circuit board traces. Danger : There is a possibility of electric shock if power is connected and danger of damage to the Mini Massive if the procedure is done wrong. This should only be done by a trained technician and ONLY ever be done with the power cable removed.
  • Page 19: Equalizers (General)

    Equalizers The only significant digital variation on the parametric concept, has been the linear phase equalizers. These are the first EQs ever EQs range from simple bass and treble controls on a hifi system to (including nature) that can change the spectral shape and not change pretty tricky parametric EQs and 1/3 octave graphic EQs.
  • Page 20: Equalizer Techniques

    EQ TECHNIQUE If mic choice is a mystery, you might want to research some Steve Albini or George Massenburg interviews. Rather than guess wrong, One of the best things about almost all EQs is that you don’t really some engineers compare 3 or 4 probable choices. Some choose the need an instruction manual.
  • Page 21 1) The song and the vocals was what producers wanted and perhaps The last problem was that they only had a few weeks to shout at each that hasn’t changed much. Bands were recorded with live vocals other. Avoid that technique. You gotta be creative, play it by ear, use back then.
  • Page 22 Rather than try to do all your compression while recording vocals, Percussion: There are two big tricks. The first is don’t trust VU save some for the mix. This takes a little pressure off of finding the meters - use peak meters and don’t get too close to full scale. The key “ultimate”...
  • Page 23 What you hear in the studio strongest features. Manley Labs is one of the very few names and what “they” hear with a subwoofer can be different, and that is commonly seen in most major mastering facilities.
  • Page 24 The Circuit If you are attempting to master the project or “pre-master” (this year’s hot, new audio buzzword) yourself, here are some suggestions. The Mini Massive is a not a particularly complicated circuit. The Take a week off after mixing, then listen to the mixes on as many audio comes in, is converted from balanced to unbalanced and DC different systems as you can, friend’s homes, cars, boom boxes, servo'd and given enough power (a few watts) to drive the EQ.
  • Page 25 Line Drivers and Interfacing And then there is the transformer output option, which remains the most forgiving and automatic method to interface given that the ouput is floating and either leg can be grounded without a loss of Most balanced line drivers are one of a few variations of cross- headroom and with less groundloop difficulties.
  • Page 26: Translations

    Translations This is just a few commonly used musical terms translated into technical terms or specific Massive Passive techniques. Note that these are fairly loose descriptions and definitions. Your mileage may vary. Bottom, Fat the deep lows for more: bell boost below 100Hz or use any low shelf up to even 330Hz. When you use a shelf this high, you should experiment with the bandwidth control.
  • Page 27: Troubleshooting

    TROUBLE-SHOOTING There are a number of possible symptoms of something not quite right, some may be interfacing, others we will touch on as well. If you suspect a problem the following paragraphs should help. NO POWER, NO INDICATORS, NADA - Probably something to do with AC power. Is it plugged in? Check the fuseon the back panel.
  • Page 28 GETTING DISTORTION WHEN WE BOOST A LOT. No doubt. The Mini Massive by itself should have enough headroom so that mega-boosts won't cause clipping in it, however, it can push out about +30dBv, 6 or 8 dB more than most gear can accept without clipping.
  • Page 29: Mains Connections

    Note: This unit has been factory wired for your country. If you plan to take the unit to countries with a different mains voltage you will need to send the Mini Massive to Manley Labs or to your Manley dealer for the correct "mods" which does involve some soldering and cutting of PCB traces - or use standard AC voltage converters.
