IGS Audio / iQ505

The only Sontec-inspired 500 Series 5-band EQ module with overlapping bands and 12dB of boost/cut.

EQ for the most transparent tone
The iQ505 is a fully parametric equalizer built into the 500 series modules.

This is a 5-band EQ with overlapping bands and 12dB of boost or cut, and the equalization range starts from sub-bass and goes up to 24kHz, usually called air. It covers a very wide frequency range, which is useful for adjusting the tone of many instruments.

All bands are also equipped with a Q knob to manage the bandwidth of each filter, and this has electronically perfectly balanced inputs and outputs using the latest THAT chip.
