Page 3: Introduction
INTRODUCTION THANK YOU!... for choosing the Langevin MINI MASSIVE STEREO EQUALIZER. This Equalizer is based on the Manley Massive Passive Stereo Tube EQ and might be described as an evolution and an alternative to the original.The Massive Passive and the Mini Massive share a number of qualities. Both are based on passive circuits comprised of resistors, capacitors and inductors to sculpt tone, in fact for the most part, the exact same circuits. -

"OUT" setting (Switch#3) so one can easily use the unit as two mono EQs. This master EQ IN switch makes auditioning and comparing the effect of the total stereo EQ extremely easy. - Page 6 5) GAIN. This sets the boost and/or cut depth or amount and works with the BOOST, OUT, CUT, TOGGLE. FLAT is fully counter-clockwise not straight up "12:00" like most EQs. 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: The Massive Passive
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 Thoughts 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 flavor of subtle 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?” The most accurate answer is “you guys are spoiled, ha ha”. To do it in digital is almost a no-brainer and is just a matter of passing a few numbers to the other sides parameter registers.
- Page 10 It had a 10 dB insertion loss. No tubes. It had boost and cut positions but boost just meant less loss. Manley Labs re-created this vintage piece and added a tube gain make-up amp for that 10 dB or make- up gain to restore unity levels.

Page 11: The Passive Parametric
A hybrid design using chips for cheapness and tubes for THD was almost opposite of how Manley Labs approaches professional audio gear and tube designs. Could we combine the best aspects of Pultecs, old console EQs and high end dedicated parametric EQs? What is the definition of a "Parametric Equalizer"? We asked the... - Page 12 Why Passive? If you hate tech talk, just skip this section - it has to do with electronic parts and circuits and design philosophy. All EQs use capacitors. They are very easy to use, predictible, cheap and simple. Some sound slightly better than others. Inductors do almost the mirror function of capacitors.
- Page 13 Phase Shift? Deadly topic. This is probably the most misunderstood term floating about in the mixing community. Lots of people blame or name phase shift for just about any audio problem that doesn't sound like typical distortion. We ask that you try to approach this subject with an open mind and forget what you may have heard about phase for now.This is not to be confused with "time alignment"...
- Page 14 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)

- Page 17 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 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 EQs range from simple bass and treble controls on a hifi system to pretty tricky parametric EQs and 1/3 octave graphic EQs. As an audio freak, you have probably tried quite a few EQs and have gotten both great results and sometimes less than great and you probably have a favorite EQ. - Page 20 EQ TECHNIQUE One of the best things about almost all EQs is that you don’t really need an instruction manual. You plug it in, turn a few knows and when nothing happens you take it out of “bypass” and the rest is easy.
- Page 21 1) The song and the vocals was what producers wanted and perhaps that hasn’t changed much. Bands were recorded with live vocals back then. Even overdubs were a band thing. Much of the signature of both the British or American sound were the vocal harmonies. Same today.
- Page 22 Rather than try to do all your compression while recording vocals, save some for the mix. This takes a little pressure off of finding the “ultimate” compressor with perfect settings and you have the option of compressing the vocals as a group. Real Drums: Typically need lots ‘o’...
- Page 23 EQs and compressors along with the digital EQs and dynamics processors, all used together and each for a few dB of its strongest features. Manley Labs is one of the very few names commonly seen in most major mastering facilities.
- Page 24 If you are attempting to master the project or “pre-master” (this year’s hot, new audio buzzword) yourself, here are some suggestions. Take a week off after mixing, then listen to the mixes on as many different systems as you can, friend’s homes, cars, boom boxes, headphones, etc.
- Page 25 Line Drivers and Interfacing Most balanced line drivers are one of a few variations of cross- coupled mixed feedback circuits. You know, the ones where you can plug in balanced, or unbalanced pin 2 or pin 3 grounded gear and are supposed to allow fool-proof transformer-like interfacing.

Page 26: 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.
