When the Q potentiometer is turned to the extreme left, the bandwidth

around the selected centre frequency is very narrow. This is known as »high 10 Q 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-FINEswitch is responsible for fine tuning of the control characteri-

stics of the Q potentiometer. When the switch is activated, the Q values 11 Q-Finechange in so that position Q3.6 (extreme left) takes on the value Q1.9. In

the 12 o'clock position (Q1), all Q values are halved. The values between Q1 and Q0.6 remain unchanged.

Q-FINEenables you to make more differentiated settings in the critical control ranges of bandwidths relevant for musical applications. Two Q values can therefore be compared more easily by switching over quickly.

The NOTCH filter of the EQ MAGIX is variable in bandwidth (Q) and there- fore, if it is used with broader bandwidths (low Q), it can also be used to filter out wide areas in the audio spectrum (e.g. lowering mids).

The FREQUENCY control is responsible for a frequency range of between 14 Hz and 58 kHz (also see point 8 FREQUENCY, page 15), thus enabling removal of interference noise such as quantization and formantization noise which can be induced by digital equipment.

The NOTCH filter's slope characteristics (known as ROLL-OFF) can be varied. After NOTCH mode has been activated, the BOOST/CUT control takes on the function of the ROLL-OFFcontrol. This means that the slope characte-

EQ MAGIX specifications

Sound Performance Lab has made a significant mark in the world of audio engineering with its EQ MAGIX, an advanced equalizer plug-in designed for professional sound production. Known for its precision and versatility, EQ MAGIX is a valuable tool for music producers, sound designers, and mastering engineers.

One of the standout features of EQ MAGIX is its intuitive user interface, which allows for seamless navigation and efficient workflow. The layout is user-friendly, presenting an array of controls that give users the ability to make precise adjustments to their audio tracks. With a clear visual representation of frequency spectra, users can quickly identify problem areas in their mixes and address them with ease.

At its core, EQ MAGIX employs sophisticated filtering technologies that ensure high-quality sound processing. It offers various filter types, including parametric, low-pass, high-pass, band-pass, and notch filters. This extensive selection enables users to tailor their sound with remarkable accuracy. The parametric filter is particularly noteworthy, allowing for precise frequency adjustments, including bandwidth control, which is essential for making subtle tonal changes.

Another key characteristic of EQ MAGIX is its support for high-resolution audio. It operates at sample rates up to 192 kHz, ensuring that the clarity and detail of your sound are maintained throughout the mixing and mastering process. This high level of audio fidelity is crucial when working in both studio environments and live settings.

The plug-in also features a dynamic EQ mode, which provides users with the ability to adapt the equalization based on the input signal's dynamics. This dynamic processing capability enhances the overall sound quality and enables greater control over how specific frequencies react to varying levels of audio, making it an indispensable tool for achieving professional mixes.

Moreover, EQ MAGIX integrates well with various digital audio workstations (DAWs), allowing for seamless incorporation into existing workflows. Its compatibility with industry-standard platforms ensures that users can easily implement it into their projects without any technical hurdles.

In conclusion, Sound Performance Lab's EQ MAGIX stands out as a robust and versatile equalizer plug-in that caters to the needs of audio professionals. With its intuitive interface, high-quality filtering technologies, dynamic processing capabilities, and high-resolution audio support, EQ MAGIX is an essential tool for anyone looking to elevate their sound production. It epitomizes the merging of functionality and user experience, making it a valuable addition to any audio engineer's toolkit.
