Overview

Massive Passive XXV Anniversary Edition

Since its release in 1998, the Manley Massive Passive has shaped the sound of countless productions around the world. Numerous renowned producers and recording and mastering engineers from around the world use it to add their own signature sound to their productions. To celebrate the Massive Passive's 25th anniversary the XXV Anniversary Edition features an attractive cobalt blue face plate equipped with a custom laser engraved artwork and is limited to 100 pieces worldwide.

Manley's Massive Passive is an equalization monster. You can expect the best strengths of Pultec-style equalizers as well as choice console, parametric, and graphic EQs - all the radical shaping you'll need for the most demanding of sessions as well as the delicate, subtle shadings needed for vocals and mastering. The 2-channel, 4-band Massive Passive features a passive tone-shaping portion of the equalizer design and uses only the best components, for its ultimately huge, high-headroom performance.

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

2-channel, 4-band EQ for everything from the radical to the subtle
The Massive Passive equalizer excels at everything from the drastic shaping needed for tracking to the most subtle of shadings needed for affecting vocal tracks or the whole mix. Although different in nature, its 2-channel, 4-band design offers a tremendous amount of sonic sculpting, incorporating the best strengths of Pultecs, choice console EQs, graphic equalizers, and parametric equalizers - but it doesn't throw color all over the audio. Get creative with it, or get logical and surgical with it - the Manley Massive Passive is ready to make the most of whatever you toss its way.

Five steep highpass filters and four steep lowpass filters
The Manley Massive Passive is packed with five highpass filters and four lowpass filters, and you can bypass either or both. The filters are steep, so you can pull out the junk without touching the real music. It's also great-sounding when combined with other bands. Ultimately, Manley went for "what's useful" when designing the Massive Passive, not "what's standard" - it's a welcome design departure that produces seriously massive results.

MANLEY POWER® Power Supply
The MANLEY POWER® power supply is an innovative design developed specifically for Manley Labs, specifically for High Voltage vacuum tubes, and specifically for audio by the world expert team in this technology led by Bruno Putzeys. Proven reliable and sonically superior in the Manley CORE, this power supply provides 300 Volt DC rails to run the vacuum tubes, beefy 6 Volt lines to power them up, along with several other voltage rails for the phantom power and various solid-state control voltages. High Voltage = High Headroom, folks. You will not get near this sonic performance with in any 500-series design. Trust us. This is Massive audio excellence which starts with this superior power supply. All lines are importantly regulated, low impedance, efficient, and super-quiet in this low radiating high frequency design. The universal mains input accepts any voltage or frequency from anywhere in the world making travel with the Massive Passive a breeze.
