Dear customer, Foreword Thank you for the confidence you have shown towards SPL electronics GmbH by purchasing the SPL EQ MAGIX. The EQ MAGIX is a first-rate Equalizer with exemplary specifications, excellent workmanship and unri- valled sound quality. Please study this owner´s manual carefully so that you can make the most of the wide range of possible applications offered by the EQ MAGIX and to ensure ease of operation. We have tried to write this manual in such a way that it is easy to under-

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 VITALIZER 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 VITALIZER means that the EQ MAGIX is not only predestined to proces

The housing of the EQ MAGIX has the standard 19" EIA format and Installation occupies 1 height unit (1 U = 44 mm) in your rack. When installing the unit in a 19" rack, the rear side of the unit needs some support, especially in a Touring Case. The EQ MAGIX should not be installed near units which produce strong magnetic fields or extreme heat. Do not install the EQ MAGIX directly above or below power amplifiers or digital processors. If possible, the EQ MAGIX should be placed in an »analog rack«

Control 6 1 5 elements Input 2 3 4 The INPUT stage of the EQ MAGIX is based on the SSM 2017 semicon- Mic / Line 1 ductor. The strengths of this particular component are its extremely low noise and distortion characteristics. Unlike discretely designed circuits, the SSM 2017 has 64 transistor functions (discretely up to 24), thus achieving a common mode rejection of over 90 dB (measured at INSERT SEND). Preamplification of the input signal is determined by the MIC/LINE control. The control range

The INPUT section of the EQ MAGIX is equipped with a PEAK LED which Peak 3 lights up approximately 3 dB below the value which would signify poten- tial overdriving of the output (INSERT SEND). The headroom of the INPUT stage is around 26.5 dB. The PEAK LED does not indicate the overdriving limit of the PARAMETRIC stage, as this varies, depending on the values set on the EQ. The PARAMETRIC stage has a lower headroom limit (+22 dB) when the stage is activated and the BOOST/CUT control is on 0dB. I

If the Active 7 switch has been pressed, the integrated LED indicates that the PARAMETRIC section has been activated. The ACTIVE funciton is a so-called "electronic bypass". Any DC voltages are filtered out via coupling capacitors. To increase the operational safety of the monitor loudspeakers, you should, however, avoid switching the parameters on or off at a loud monitor volume levels. At high amplitudes

Practical applications bring accurate processing of subwoofer tracks to mind, along with a problem which modern recording procedures (PCM, hard disk, samplers etc.) frequently involve; here, the frequencies recorded are often in the infra-sonic frequency range (digital coding). When they are reproduced (which involves D/A conversion), low-frequency signal portions can cause phase distortions in the audible range, creating secondary effects which cannot be corrected subsequently. The EQ MAGIX can

When the Q potentiometer is turned to the extreme left, the bandwidth Q 10 around the selected centre frequency is very narrow. This is known as »high Q« with a value of Q3.6. When it is turned to the extreme right, the selected bandwidth is of maximum width, i.e. »low Q«. The value is Q0.6. The bandwidth factor is calculated from the width of the frequency curve on the -3 dB points relative to the 0 dB line. The below diagram shows various Q values at a centre frequency of 1 kHz: The Q-FINE swi

I Im mp po or rt ta an nt t: : If you switch on the NOTCH mode, the bandwidth control Q must be set at 0.6 (extreme right), so as to ensure a 1:1 level ratio with the original signal. Narrower notches can be obtained if the Q control is turned to the extreme left. However, then the output level is also reduced by around 20dB. Figure 4 shows the curves for the NOTCH with GENTLE and STEEP characte- ristics at Q0.

Introduction into ® the VITALIZER If you are working with a VITALIZER filter network for the very first time, it is advisable to operate the control parameters in a certain order to achieve optimum results as quickly as possible. You should use a mono signal of good quality as a signal source. You can either preamplify it in the INPUT section or feed it directly into the INSERT RETURN, so that the signal goes directly into the PARAMETRIC section.
