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. Offering incredible sculpting abilities, without all the coloration, the Massive Passive may well be your last equalizer.
The Filters
5 frequencies Hi Pass and bypass, PLUS 5 frequencies Lo Pass with bypass. We made them extra steep. 36 dB/oct ! Why? When you need to remove the garbage, this does the trick and allows more of the real music to be untouched. The other reason is that it sounds killer when combined with the regular bands. Towards the mids this degree of steepness may be tamed somewhat. We're going for pure "usefulness" not "well, we guess it's standard". Thinking drums and guitar stacks, and other tough jobs. These filters are passive too.
High Pass Filters = 22, 39, 68, 120, 220, OFF
Low Pass Filters = 6K, 7K5, 9K, 12K, 18K, OFF
Parametric Frequencies
LOW - 22, 33, 47, 68, 100, 150, 220, 330, 470, 680, 1K
LM - 82, 120, 180, 270, 390, 560, 820, 1K2, 1K8, 2K7, 3K9
HM - 220, 330, 470, 680, 1K, 1K5, 2K2, 3K3, 4K7, 6K8, 10K
HI - 560, 820, 1K2, 1K8, 2K7, 3K9, 5K6, 8K2, 12K, 16K, 27K
Steep LP and HP filters for maximum effectiveness and achieved passively for minimal coloration. The minimum slope is 18 dB/octave and the 18kHz filter was designed for 60 dB/octave
Modular design that allows future upgrades and special functions. The Massive Passive is an "EQ platform" with room to grow.
Transformer balanced floating outputs for ease of installation and a touch of desirable flavor. These too were custom designed for the Massive Passive to accommodate the huge boosts possible.
