A Mastering Version of the Acclaimed Massive Passive!

The Manley Massive Passive Mastering Version equalizer features a simple, passive design - not a standard parametric design - for more natural, organic shaping. It also offers mechanically detented knobs for both Gain and Bandwidth controls, so you can easily repeat your settings. On the Massive Passive Mastering Version, both the Gain and Bandwidth controls intentionally interact, and the bands interact, as well - this creates an incredible-sounding result without sounding "colored" or "processed." Also, both higher and lower than the normal version, the Manley Massive Passive Mastering Version's filters are tailored to mastering purposes.

Manley Massive Passive Mastering Version Equalizer at a Glance:
  • Premium design with passive components
  • Mechanically detented knobs
  • Gain and Bandwidth controls interact, as do the bands
  • Specially tweaked for mastering

Premium design with passive components
As you can expect from Manley, no corners were cut with the design of the Massive Passive Mastering Version, and there's no unnecessarily complicated circuit - Massive Passive Mastering Version features basic passive components and uses only metal film resistors, film capacitors, and hand-wound inductors to sculpt the sound.

Mechanically detented knobs
Your settings are completely loggable on the Manley Massive Passive Mastering Version. Manley found a way to mechanically detent the Gain and Bandwidth controls, ensuring repeatability - without adding the extra cost and space problems that Grayhill switches would have caused.

Gain and Bandwidth controls interact, as do the bands
On the Manley Massive Passive Mastering Version, both Gain and Bandwidth controls intentionally interact, as do the parallel-design bands. You can boost a band 20dB while boosting another band at that frequency for minimal change - on most equalizers, the two bands add - so you boost 40dB into clipping. Due to this interaction, predictable step sizes are unrealistic - but the settings are repeatable when logged - and the interact bands contribute to the Massive Passive Mastering Version's excellent sound.

Specially tweaked for mastering
The Manley Massive Passive Mastering Version is tailored to mastering needs. Its filters are both higher and lower than the regular Massive Passive. In addition, the Master Gain Trim Controls are true 11-position, 1/2dB, stepped Grayhill switches ranging between -2.5 to +2.5dB of trim, making left/right matching and calibration easier.

Legendary EQ

I first became aware of the Massive Passive about 20-something years ago when I was working with ADATs and a Soundtracs Topaz 8-buss board. At the time I could only dream about getting one. Now, my studio situation at the point that I was able to get one -- a dream come true. So, does the unit live up to my expectations? Short answer -- it exceeded them.While the mastering version is obviously geared for mastering use, I found it highly usable for giving tone and weight to individual stereo tracks for mixing, such as drum busses, stereo guitar busses and two stereo piano recordings. The difference between the mastering version and the regular version is that the mastering versions knobs are all stepped, whereas the mix version's controls are continuous. Additionally, according to the user manual, the boast/cut controls offer greater gain/attenuation on the mix version than the mastering version. Still, I find a notch or two cut or gain change makes a big difference on the signals.Attenuating frequencies on the MP is counter-intuitive at first because you first have to select the frequency that you wish to cut, engage the "cut" switch and then turn the gain control clockwise as if you were increasing the gain on another EQ. However, it quickly becomes second nature once you do a session with the unit.The sound? Glorious and rich are the words that come to mind. Simply passing your signal through the MP, without any frequency gain or reduction changes instantly gives a subtle, though noticeable bigness and clarity to the sound. So far, I've used the MP on mastering an R&B album, a heavy metal track to be used in a movie trailer (as well as the trailer itself in post-production) and for an acoustic jazz EP. In all cases, the MP gave me everything I needed. I never felt the need to bring in a multi-band compressor or other specialty processor. My mastering chain now consists of the Slate VTM into the Shadow Hills Vandergraph followed by the MP and finally the UAD Precision Limiter.In sum, in using the MP, I feel like I'm almost cheating in being able to get a rich, warm character on whatever signal I pass through it.I also have the UAD version of the MP and I was able to make a side-by-side comparison between the UAD version and the real deal. My findings? While the UAD is close and it is a fine EQ in its own right, there is a discernable difference between the two. First off, the UAD is about a 0.5 dB to 1 dB hotter at unity gain than the real unit. Secondly, the real Manley is far more graceful when you push it. The plug-in tends to lose its warmth when pushed whereas the Manley still shines when pushed.Most noticeable, however, is that the Manley simply has more organic vibe and girth that the software does not quite replicate. Perhaps it's the transformers? Perhaps it's the inherent noise (albeit low level) that analog introduces into the signal? Whatever it is, the real deal is simply more pleasing to listen to. Obviously, spending over $5k on 2-channels of EQ is not an impulse purchase. However, if you have the client base to justify the special magic that the hardware Manley MP gives, it is definitely worth every penny.
