MMMSMP - Manley Massive Passive Mastering - Passive Four-band Stereo Tube EQ - Mastering Version
The Manley Massive Passive Mastering Version equalizer features a simple, passive design - not a standard parametric design - for more natural, organic shaping. It also offers mechanically detented knobs for both Gain and Bandwidth controls, so you can easily repeat your settings. On the Massive Passive Mastering Version, both the Gain and Bandwidth controls intentionally interact, and the bands interact, as well - this creates an incredible-sounding result without sounding "colored" or "processed." Also, both higher and lower than the normal version, the Manley Massive Passive Mastering Version's filters are tailored to mastering purposes.
Premium design with passive components
As you can expect from Manley, no corners were cut with the design of the Massive Passive Mastering Version, and there's no unnecessarily complicated circuit - Massive Passive Mastering Version features basic passive components and uses only metal film resistors, film capacitors, and hand-wound inductors to sculpt the sound.
Mechanically detented knobs
Your settings are completely loggable on the Manley Massive Passive Mastering Version. Manley found a way to mechanically detent the Gain and Bandwidth controls, ensuring repeatability - without adding the extra cost and space problems that Grayhill switches would have caused.
Gain and Bandwidth controls interact, as do the bands
On the Manley Massive Passive Mastering Version, both Gain and Bandwidth controls intentionally interact, as do the parallel-design bands. You can boost a band while boosting another band at that frequency for minimal change - on most equalizers, the two bands add - so you boost into clipping. Due to this interaction, predictable step sizes are unrealistic - but the settings are repeatable when logged - and the interact bands contribute to the Massive Passive Mastering Version's excellent sound.
Specially tweaked for mastering
The Manley Massive Passive Mastering Version is tailored to mastering needs. Its filters are both higher and lower than the regular Massive Passive. In addition, the Master Gain Trim Controls are true 11-position, 1/2dB, stepped Grayhill switches ranging between -2.5 to +2.5dB of trim, making left/right matching and calibration easier.
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.
