The MANLEY POWER® power supply is an innovative design developed specifically for Manley Labs, specifically for high voltage valves and specifically for audio by the worldwide team of experts in this technology led by Bruno Putzeys. Proven to be reliable and sonically superior to the Manley CORE, this power supply provides 300 Volt DC rails to run the vacuum tubes, robust 6 Volt lines to power them, along with several other voltage rails for phantom power and various voltages. solid state control. . High Voltage = High Headroom, folks. You won't come close to this sonic performance in any 500 series design. Trust us. This is Massive audio excellence that starts with this superior power supply. All lines are importantly regulated, low impedance, efficient and super quiet in this low radiation, high frequency design. The universal mains input accepts any voltage or frequency from anywhere in the world, making traveling with Massive Passive much easier.
Note: This upgraded Massive Passive with MANLEY POWER is distinguished from the previous version by its red backlit power button on the front panel, as opposed to the black rotary button used on previous versions.
HIGH PASS FILTERS
22, 39, 68, 120, 220 Hz, OFF
LOW PASS FILTERS
18 kHz, 12 kHz, 9 kHz, 7K5, 6 kHz, OFF
There are 5 passive high-pass and bypass filters, as well as 5 passive low-pass filters with bypass. We made them even steeper. Why? This way you can take out the trash and not mess up your music. The way these filters interact with the parametric EQ bands simply sounds beautiful. Higher Low Pass filters get even steeper. Attack drums, guitar stacks and other tough jobs. Make "telephone" voice sounds for special effects.
LOW
22, 33, 47, 68, 100, 150, 220, 330, 470, 680, 1K
MEDIUM BASS
82, 120, 180, 270, 390, 560, 820, 1K2, 1K8, 2K7, 3K9
HIGH MEDIUM
220, 330, 470, 680, 1K, 1K5, 2K2, 3K3, 4K7, 6K8, 10K
HIGH
560, 820, 1K2, 1K8, 2K7, 3K9, 5K6, 8K2, 12K, 16K, 27K
Each band can be ignored or set to increase or decrease. This provides twice the control resolution over conventional equalizers. It also eliminates the problem of a central detent not guaranteeing a flat response.
Each band is capable of 20 dB of boost or cut combined with incredible headroom and clipping freedom.
Steep LP and HP filters for maximum effectiveness and passively achieved for minimal staining. Low-pass filters get progressively steeper as the frequency point increases. All high-pass filters and the 6K, 7K5, and 9KHz low-pass filter slopes are 18 dB/octave, the 12kHz low-pass filter has a slope of 24dB/octave, and the 18kHz filter has a slope of 60 dB per octave.
Transformer-balanced floating outputs for ease of installation and a hint of desirable flavor. They were also custom designed for Massive Passive to accommodate the huge increases possible.
Manley quality, Manley engineering and the "Manley Sound".
