Massive-Passive Sound in a Mini Langevin Box? Langevin Mini-Massive| April, 2007With frequency bands identical to bands one and four of Manley Labs’ highly-regarded Massive Passive EQ, the same passive components (resistors and capacitors) and incredibly similar circuits, the brand new Langevin Mini-Massive is a two-band solid state “kid brother” stereo EQ that’s generating quite a buzz. But while Manley claims that the main difference (besides number of bands) between the two boxes is that the four-band Massive Passive uses tubes for gain while the two-band Mini uses solid state Rapture gain blocks, I wasn’t content to just take that word as gospel. So I requested a unit to investigate if that is where the similarities really begin and the differences end . . . here’s what I found. INSIDE THE MINI-MASSIVEIs the Langevin Mini-Massive really a Mini-Manley Massive Passive? Yes and no. Many of the same components are used in both, and the Rapture amps, while solid state, are super clean and fast (more akin to a GML, in terms of speed and neutrality, than a Langevin PEQ-2 or Pultec EQP-1A3.) Furthermore, the Mini-Massive is as meticulously constructed as its big brother — you won’t find any cheap circuit boards here. The Mini-Massive boasts a triple option toggle per band: boost, out, and cut. Another toggle selects between shelf or bell curves. A Bandwidth control alters the area and shape of each EQ curve-response. Having a shelf with the ability to control the slope is a great feature, lending the Mini to more flexible applications. With the Q control you can adjust the band to be wider or narrower. (Tip: A boosted signal generally sounds nicer with a larger Q, but when removing certain frequencies a smaller bell is more desirable. The reason why is that when you have a frequency that needs to be reduced, you don’t want to alter the neighboring frequencies; instead you want more of a “concentrated” reduction. But for boosting, the larger bell definitely sounds more natural.) On the high bands, there is a second Bell shape for the four highest frequencies — a feature that can be of great use as the bell is more concentrated on certain frequencies. “Bell 2” is not found on the Manley Massive Passive, but it is sure a welcome feature here on the Langevin unit. Another difference compared to the Manley Massive Passive: The four lowest shelf curves were reshaped for extra fatness, depth, and punch on the Langevin Mini-Massive. A transformer switch on the back of the unit allows you to bypass the output transformer in the down position. In the middle position, the signal goes through the transformer, giving a slightly warmer and smoother color, while the upper position exaggerates the transformer by increasing even order distortions, meant to simulate some Class A British console circuits for a grittier sound. The difference between using the bypass or the transformer, at first, is subtle. But though the results may be minor on one track, when applied across, say, ten or more tracks, the effect can be cumulative.
