Crane Song Insigna is 3-band valve EQ for the 500 Series format with high and low cut filters.
Crane Song Insigna features at its core, a dual triode circuit with a 12AX7 tube. All the three bands offer a selection of eight centre frequencies with both the Low and high band being shelving bands. Buffered RC circuits are used in the negative feedback path around the valve amplifiers for an impressively fat sound rich in second harmonic.
The High-Pass and Low-Pass filters use steep 24dB/oct filters and offer a choice of 7 frequencies each.
