Manley Massive Passive
The Manley 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 the EQ design not using any active circuitry. Only metal film resistors, film capacitors and hand-wound inductors sculpt the sound. Super beefy, hugely-high-headroom, Manley all-tube make-up gain amplifiers deliver your tunes into the next realm. 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.
Operating Mains Voltage
Units are purpose built for original destination country's mains voltage: 100V, 120V, or 220-240VAC as indicated on the serial number badge. Power transformer must be replaced in order to change mains operating voltage.
120VAC units may NOT be rewired to put the primaries of the power transformer in series for 220-240V operation or a large radiated field of hum will develop. If changing locations/voltages, the power transformer must be replaced with the dedicated one for the voltage at which it will operate.
