The EQ MAGIX features a PARAMETRIC constant-Q equaliser combined with the VITALIZER equaliser system.

This combination of filters is based on the assumption that after succes- sful microphoning, you only have one problem zone, if at all, that needs to be equalized. The VITALIZER provides all the necessary circuitry for creative sound post-processing.

The EQ MAGIX provides a total of five processing ranges: the PARAME- TRIC section provides an extremely variable and efficient filter for selective intervention in a frequency band between 14Hz and 58kHz. The VITA- LIZER interferes in 4 frequency ranges, bass, mid and treble, along with the harmonical frequencies pertaining to even and odd overtones.

The PARAMETRIC section is designed to clean up one »problem zone« in the frequency spectrum of the recorded instrument or voice perfectly, without prejudicing the sound and without being inhibited by technical limitations of standardized filter circuits.

The equalizer used in the EQ MAGIX is based on the state-variable filter type (SVF). Its function is phase-stable and neutral right down to 14 Hz in the infra-sonic range. The frequency range extends right up to breath- taking 58 kHz! This initially provides a platform for experimentation as to whether interspersing digital components affects into the tonal perception range (16 Hz to 20 kHz) or whether the removal thereof can remedy sound problems directly or indirectly.

We have visited sound engineers and producers in European and American audio and video studios and they pointed out to us that inter- spersing the sample rate frequencies (44.1 kHz and 48 kHz) into the audio path is a well-known phenomenon, whereby subharmonic elements can be transposed right down into the audible frequency spectrum. Furthermore, this can result in audible phase shifts and distortions. With the EQ MAGIX, you can now influence these frequencies actively. The sample rate frequencies are inscribed on the scale (44, 48).

All frequencies can be boosted or cut with 15dB throughout the entire frequency range from 14 Hz to 58 kHz. The PARAMETRIC equalizer of the EQ MAGIX is based on the constant-Q principle and provides an »inversible Q«, i.e. when filtering out a interfering frequency, inverting the boost value to a cut value results in precise inversion of the bandwidth (Q) values.

Notching is also possible with a variable ROLL-OFFto select a STEEP or GENTLE filter slope.

Extremely flexible bandwidth defintion allows Q values between 0.6 and 3.6.

The PARAMETRIC section serves to perfectly remove any interference frequency or to accentuate a frequency band as desired.

With its enormous range of frequencies from 14 Hz to 58 kHz, the EQ MAGIX provides a plat- form for experimentation as to the extent signal portions affect the tonal perception range beyond the spectrum of the human hearing.
