SPECTRUM SPLITTER is a crossover that slices your instrument into low and mid/high halves and sends each band to its own FX path — parallel dirt on lows, modulation or pitch on top, bi-amp-style blends, or any other split-band madness you wire up. Processing bands separately keeps the low end from choking the definition up top (and vice versa), so you can chase tones that would be a mess with everything in one serial chain. Three outputs: FULL — full-range dry / sum feed LOW — everything below the split frequency HIGH — everything above the split frequency Per-output trims from 0 dB to +6 dB, plus a variable split frequency so you can place the seam where the song needs it. power: 9V DC under 50mA — standard 5.5/2.1 jack (center-negative) premium, name-brand parts solid metal enclosure dimensions: 114mm x 64mm (+ approx. 3mm for 1/4" jacks)
