The new version of SIMON adds a mathematically perfect model of the OP-AMP from a tube mastering equalizer, with three L/R matrix modes: EQUAL - both channels share the same harmonic structure; MODERN - each channel carries a subtly different harmonic structure; and VINTAGE - each channel has a distinctly different harmonic structure. We have also modelled further non-linearities that bring dynamics, liveliness and musicality into the whole system - surpassing the hardware original.
A true mastering equalizer
SIMON centre section with the wordmark and INPUT TRIM
Two independent channels, each with high and low shelves, three fully parametric bands and its own output trim — a complete, symmetrical mastering EQ built around a central INPUT TRIM that feeds the analog-style saturation stage. With AGC on, the level leaving the EQ is matched automatically, so you can equalize freely without driving the saturation any harder.
Three parametric bands
LOW, MID and HIGH — each with its own GAIN, stepped Q and a mastering-grade frequency grid, on both channels. Broad and musical for tone-shaping, tight and surgical when you need to fix a single frequency, with exact, repeatable recalls.
Musical high & low shelves
A broad high-frequency shelf for air and top-end weight, and a low shelf switchable at 50 or 100 Hz for warmth and bottom-end control — the classic, gentle mastering moves that sit outside the parametric bands.
Analog-style saturation
INPUT TRIM drives a built-in analog-style saturator — the harder you push, the more harmonic colour and density SIMON adds. The live SAT indicator shows exactly how hard it is working, and the per-channel OUTPUT trim lets you match level so you judge tone, not loudness.
Link & Mid/Side
LINK ties the left and right controls together for fast, symmetrical stereo moves. M/S switches processing from Left/Right to Mid/Side, so you can equalize the centre and the stereo sides independently — mastering-grade stereo control.
