IGS AUDIO IQ – stereo active equalizer
IGS IQ Double Qualizer is a modern application of the noble sound of analog correctors. 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 application
correction it maintains neutrality and clarity in 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.
Band 1 (SUB): 50-300 Hz (shelf)
Band 2 (LOW): 60-1k Hz (peak)
Band 3 (MID): 1k-16k Hz (peak)
Band 4 (HIGH): 2k-10k Hz (shelf)
Typical usage:
–
Great mastering equalizer, due to its excellent channel convergence.
–
Very good on vocals, guitars and strings – adds fat bottom and crispy high frequencies
