The Trident Hi-Lo 500 Series Tracking Filters are dynamic 500 Series modules featuring independently adjustable high-pass (Lo-Cut) and low-pass (Hi-Cut) filters with selectable 12dB or 24dB per octave slopes and up to +12dB resonance. Designed to automatically track and respond to input signals, they offer precise tonal shaping for mixing, mastering, and live sound. With features like peak indicators and the ability to link modules for steeper slopes (up to 48dB/octave), they provide both corrective and creative filtering in a compact, versatile format.
