The 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. You'll need to experience this.

Creating natural, organic, acoustic tone can only be done with an equalizer that shapes the signal with natural methods. The Massive Passive uses simple passive components and exploits their natural qualities rather than forcing a complex circuit to meet an arbitrary clinical or scientific goal. Manley knows that recording and mastering equalizers are used by artists for artistic goals and they balanced this design with a little more art than science.

The Massive Passive is intended both for the most radical EQ sometimes needed for tracking as well as the most subtle shadings for vocals and mastering. It is designed to be a fundamentally different EQ but with the best strengths of Pultecs, choice console EQs, parametrics and graphics. The difference is that this EQ allows twice as much EQ with half the colouration. It allows massive HF boosts without sibilance problems and unbelievable fatness without mud. This is unique. Being different also gives it some quirks and idiosyncrasies that will spark your creativity.
