Manley Massive Passive Stereo Tube Equalizer

The MASSIVE PASSIVE is a two channel, four band equalizer, with additional high pass and low pass filters. Passive refers to the tone shaping part of this clever new 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.

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
• HP and LP Filters plus gain trims
