Eq Bands (Main Section) - Arturia EQ SITRAL-295 User Manual

4.2.3. EQ Bands (Main Section)

This is the main section of the plug-in. Here, you control the three EQ bands and the two
filters. Don't be fooled by the apparent simplicity of the EQ. It is capable of very powerful
and musical results, despite the reduced number of bands and controls.
4.2.3.1. High-Pass (Low-Cut) Filter Frequency
This knob controls the low-cut frequency (high-pass filter) of the SITRAL-295. The low-cut
filter cuts the lower frequencies, preventing interference or unwanted low frequencies from
influencing the overall audio volume.
Lower frequencies have a string audio energy, which reflects in the overall audio volume
(sometimes even without being heard, but simply "muffling" the audio). Filtering the lower
frequencies can contribute to a clearer audio output and a lower overall output volume
without perceived influence on the loudness.
The filter is off by default, but can be activated by simply turning the knob. It starts at 20 Hz
and goes up to 320 Hz. The knob is continuous, but can also be stepped just like the other
controls by pressing the Stepped Controls" button in the Lower Toolbar.
4.2.3.2. Low Shelf Frequency switch
This switch controls the center frequency for the Low Frequency band. As this is a switch,
the frequencies are not continuous. You can only choose between 50 Hz, 100 Hz and 300
Hz. By default, the LF band is set to 300 Hz.
4.2.3.3. Low Shelf Gain
This knob controls the boost/attenuation of the low frequency band of the EQ. The range,
set globally for all frequencies, is very soft and broad. The frequency is switchable, with a
choice of three values.
The gain knob allows for continuous values, contrary to the original behavior. For an extra
touch of realism, you can switch on the "Stepped Controls" button in the Lower Toolbar and
have the knob "jump" between the fixed values marked on the panel.
Gain changes between -15 dB and 15 dB. By default, it's 0 (no boost or attenuation).
