  • Product Description

    The Manley Massive Passive is a stereo four-band tube equalizer with additional high pass and low pass filters.

    "Passive" refers to the tone shaping part of this clever EQ design not using any active circuitry. Only metal film resistors, film capacitors and hand-wound inductors sculpt the sound, kinda like a Pultec EQ on hyper-steroids. Super-beefy, hugely-high-headroom Manley all-tube make-up gain amplifiers deliver your tunes into the next realm. "Massive".... it's a fitting word for this beast.

    Creating natural, organic, acoustic tone can only be done with an equalizer that treats 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.

    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 incorporates the best strengths of Pultecs, choice console EQs, parametrics and graphics. The difference is that the Massive allows twice as much EQ with half the coloration. It allows huge HF boosts without sibilance problems and unbelievable fatness without mud.

    • High Pass Filters = 22, 39, 68, 120, 220 Hz, OFF
    • Low Pass Filters = 6, 7.5, 9, 12, 18 kHz, OFF
    • Low - 22, 33, 47, 68, 100, 150, 220, 330, 470, 680, 1000 Hz
    • Low-Mid - 82, 120, 180, 270, 390, 560, 820 Hz; 1.2, 1.8, 2.7, 3.9 kHz
    • High-Mid - 220, 330, 470, 680 Hz; 1, 1.5, 2.2, 3.3, 4.7, 6.8, 10 kHz
    • High - 560, 820 Hz; 1,2, 1.8, 2.7, 3.9, 5.6, 8.2, 12, 16, 27 kHz

    Each band can be bypassed or set to boost or cut up to 20 dB. This provides twice the control resolution over conventional EQs. It also eliminates the problem of a center detent not guaranteeing flat response.

    Steep LP and HP filters for maximum effectiveness and achieved passively for minimal coloration. Low Pass Filters get progressively steeper as the frequency point rises. All of the High Pass Filters, and the Low Pass 6K, 7K5, and 9KHz Filter slopes are 18 dB/octave, the Low Pass 12kHz filter has a 24dB/octave slope and the 18kHz filter has a 60 dB per octave slope.
