A massive passive stereo tube eq Colossal, timbre-twisting passive equalization using metal-film resistors, film capacitors, and hand-wound inductors to organically sculpt the tone from subtle to vivid. Manley’s tube stages handle huge HF boosts without sibilance and unbelievable fatness without mud. “It’s like a Pultec on steroids.”Each band can be bypassed or set to boost or cut. This provides twice the control resolution over conventional EQs. It also eliminates the problem of a center detent not guaranteeing flat response.Each band is capable of 20 dB of boost or cut combined with amazing headroom and freedom from clipping.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.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.Features: All-Passive tone sculpting circuitry Unique Shelf curves use the "bandwidth" control Overlapping and Interleaved Frequency choices Every band switchable to shelf or bell Vacuum tube make-up gain and line drivers Parallel symmetrical topology Premium components throughout Passive HP and LP Filters plus gain trims
