iQ. Inductor Equalizer

The sweetest parametric EQ

Inductors affect the sound in a beautiful way. They can saturate just like transformers do.

Precise & All stepped control. Not your grandpa’s EQ.

IGS IQ Equalizer is a modern application of the noble sound of analog equalizers. This very precise, parametric equalizer works great on every stage of production. It can add marvelous color to the signal, while maintaining the whole character of the original sound. This is a unique phenomenon possible only with analog processing. As opposed to digital eq it maintains neutrality and clarity on every setting. The simultaneous boosting and cutting of similar frequencies are the core secret of this device.

This is the typical effect of analog filters in the audio path. Most of the sound correction is in micro-manipulation. The frequency range is divided into 4 bands: Sub, Bass, Mid, High. In every band the frequency and boost/cut level can be set.

Finally an inductor EQ with the full, precise control engineers have been waiting for

The frequency range is divided into 4 bands: Sub, Bass, Mid, High, allowing you to control the frequency, boost/cut, bandwidth and bypass of each band! Now imagine two channels of that!!
