Page 3: Introduction
INTRODUCTION THANK YOU!... for choosing the Manley MASSIVE PASSIVE STEREO TUBE EQUALIZER. This EQ is supposed to be somewhat different from any EQ you may have used before , as well, this manual may be a bit unusual in that you may find it worthwhile to read. Even though at first glance the Massive Passive looks fairly conventional, you should take an hour and read this manual before you jump to conclusions or confusions. -

Each band has individual toggles to select whether that band will boost or cut or be bypassed. "OUT" is a hardwire bypass for that band. Unlike most EQs, you must select boost or cut for each band. There are several good reasons for this arrangement.
- Page 7 "constant bandwidth" the RF engineers appreciate. This is either deliberate or the result of trying to squeeze too much range out of a simple inductor. Manley Labs prefers the bell shape to remain relatively constant at all frequencies and the Massivo uses 14 tap inductors with low DCR to provide this.

Page 8: Credits
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"... -

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 10: 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 11: Why Passive, Why Parallel
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 12: Phase Shift, Why Tubes
Why Tube Gain Stages? The stupid answer is the name on the unit is "Manley Labs" and that is what we do. Unlike a current trend, we do not use tubes for THD, clipping character, cool marketing buzz-words, or plagiarism. - Page 13 LOW SHELF CURVES Just like most EQs, a 100Hz low shelf doesn't reach "max" until about 10 Hz. 22Hz and 33Hz are different shelves when the Bandwidth is Narrow The top graph is for the other 20 Low shelves Normal Shelf Wide Bandwidth (slope =about 4 to 5 dB/oct) Special Shelf Medium Bandwidth (slope = about 8 to 10 dB/oct)

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: 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 more towards straight up or towards narrow. -
Page 26: 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 27 IT MAKES NOISES WHEN THE FRONT PANEL IS TAPPED - An easy one. Some tubes become microphonic over time. That means they start acting like a bad microphone. Vibration has caused the supports for the little parts in the tube to loosen and now the tube is sensitive to vibration.
