Natural Sound Preservation
The Manley Massive Passive utilizes passive components in its EQ design, reducing distortion and doubling the EQ capability with minimal coloration, delivering a purer, more natural tone.
Manley Massive Passive
The Manley Massive Passive uses passive components for its equalisation and exploits their natural qualities avoiding the distortion inherent to active circuitry. As a result, the Massive Passive can provide twice the amount of EQ with half the colouration of most designs for a truly natural tone.
Unique EQ Design
Incorporating the strengths of Pultec designs, as well as some choice console EQs parametric and graphics, the Massive Passive is nonetheless a truly different EQ. From subtle enhancements to radical sound-shaping this audio equalizer does it all. For example heavy HF boosts will add a lot of presence to vocals without adding sibilance, and LF will add heft without mud.
Unlike most EQ designs, All four bands of the Massive Passive are not built in series but in parallel. This means that overlapping frequencies do not suffer from the cumulative effect of tweaking each band.
As each band works from the exact same source, the result is much more transparent. Each band can be set to bypass, boost or cut as well as a bell or shelf. Each band is capable of 20dB of boost or cut with impressive headroom. Five extremely steep high-pass and low pass filters are also added to remove unwanted frequencies such as low-end rumble. Both HPF and LPF interact with the main parametric EQ section.
New Manley Power
Since the start of 2020 the Massive Passive now includes the new MANLEY POWER Switch-Mode Power Supply.
Designed for Manley by Bruno Putzeys this new power supply provides 300 Volt DC rails to run the valves and 6 Volt lines to power them up providing extra realiabilty and sonic improvements throughout the Massive Passive and other designs.

KEY FEATURES
Unique Parallel EQ Bands
All four EQ bands operate in parallel, not series, preventing the cumulative effect of frequency tweaking, thus maintaining transparency and coherence in sound manipulation for a more refined audio output.
Advanced Power Supply
Introduced in 2020, the MANLEY POWER Switch-Mode Power Supply enhances the Massive Passive by providing stable, high-voltage rails and efficient power management, resulting in improved reliability and sonic quality across the device.

“It’s a perfect combination between modern convenience and the great, classic, sweet EQs that I love, like the Pultecs. It’s probably – no, almost definitely the best analogue EQ in existence.”
