equalizer of the EQ MAGIX is based on SVF design (state-variable-filter)
and provides a operation frequency range between 14 Hz and 58 kHz. The
integrated V ITALIZER was developed by SPL and has achieved a significant
degree of popularity over the years. The filter concept works on the basis of
psychoacoustic sound principles and is therefore ideal to achieve creative
sound effects.
The combination of a flexible parametric EQ and V ITALIZER means that
the EQ MAGIX is not only predestined to process the sounds of acoustic
instruments but also to post-process samples or poor quality Sync audio
tracks, ranging from the elimination of aliasing artefacts or other digital
interferences to the addition of sub basses or comprehensive sound impro-
vements via the V ITALIZER .
The EQ MAGIX provides you with equalizer technology which is unri-
valled in comparable units. You will find that this equalizer can not only be
set quickly and accurately at the desired frequencies but, with the aid of
loudness sound control, can also form sound patterns which cannot be
achieved with conventional equalizers.
The section below contains a brief description of the EQ MAGIX's func-
tion groups:
1. II N NP PU UT T : Microphone and line level signals can be preamplified in the
I NPUT section. Microphone signals can be preamplified up to 65 dB.
Activating the L INE switch attenuates the preamplifiers stage by -30 dB.
There is a phantom power supply (48 V) for condensor microphones. The
P HASE R EVERSE switch is used to change the polarity of the microphone. The
P EAK LED provides adequate warning of potential overdriving of the
output stages in the I NPUT section.
2. II N NS SE ER RT T : Additional sound processing equipment such as a compressor,
de-esser or reverb can be looped into the EQ MAGIX via the I NSERT jacks.
The I NPUT section can be used separately for one signal, whilst the equa-
lizer sections are available for a second signal. Use the I NSERT S END as the
output for the I NPUT section and the I NSERT R ETURN as the input for the
second signal.
3. P P A AR RA AM ME ET TR RIIC C : The P ARAMETRIC equalizer is to boost or cut different
frequencies or to cut out specific interference noise signals. It is, in a
manner of speaking, a corrective instrument in the EQ MAGIX chain of
sound-processing tools. The P ARAMETRIC works according to the constant-Q
principle. The frequency ranges between 14 Hz and 58 kHz. The control
characteristics of the bandwidth (Q) control ranges from Q0.6 to Q3.6 and
can be sensitized via the Q-F INE switch to set more subtle Q values. The
boost or cut range is max. +/-15dB. The integrated N OTCH filter can be
controlled in frequency, bandwidth and also in the filter slope (R OLL - OFF )
from gentle decreasing or increasing (G ENTLE ) to steeply decreasing or
increasing (S TEEP ). This significantly increases the tonal flexibility of the
N OTCH Filter.
