Manley Massive Passive

Colossal, timbre-twisting passive equalization using metal-film resistors, film capacitors, and hand-wound inductors to organically sculpt the tone from subtle to vivid. Manley’s tube stages handle huge HF boosts without sibilance and unbelievable fatness without mud. “It’s like a Pultec on steroids.”

he MASSIVE PASSIVE is a two channel, four band equalizer, with additional high pass and low pass filters. "Passive" refers to the tone shaping part of this clever new EQ design not using any active circuitry. Only metal film resistors, film capacitors and hand-wound inductors sculpt the sound, kinda like a Pultec EQ on hyper-steroids. Super-beefy, hugely-high-headroom Manley all-tube make-up gain amplifiers deliver your tunes into the next realm. "Massive".... it's a fitting word for this beast. You'll need to experience this.

THE MASTERING VERSION
WE CAME UP WITH A CLEVER WAY TO PULL THIS OFF...

...WITHOUT breaking your bank account, thanks to these interesting mechanically detented knobs for the GAIN and BANDWIDTH controls! These knobs are of our own design. They are a clever two-part metal design using a ball and spring detent system. They ensure repeatability and a good, positive feel, without the incredible cost and space problems tons of Grayhill switches would have caused.

We have seen in the past that the only engineers who have asked about a mastering version had yet to try the Massive. Using your previous extensive and intensive experience with other EQs may be a mistake, especially if you expect the Massive Passive to be roughly similar to them. It isn't. Please, try it first, then decide.
