Chapter 11. Mastering > Using the MClass Equalizer

Using the MClass Equalizer

The MClass EQ sits first in the signal path to correct frequency spikes or imbalances that would otherwise “top” your compressor/ limiters later in the chain. The controls are designed for fine compensation, correction, or enhancement of frequency areas that are thin or oversaturated. The curve in the display window shows the effect of all except the Lo Cut button.

To adjust the MClass Equalizer

With your song playing and an MClass Mastering Suite loaded, set the MClass Equalizer Bypass switch to On (Figure 11.2).

Figure 11.2. Enable the MClass Equalizer.

In the MClass EQ, use the five enable buttons to select frequency bands for adjustment. Enable the Lo Cut band if you want to protect against subsonic sound.

In an enabled frequency band, use the Freq knob to adjust the EQ frequency.

In the Lo Shelf band, all frequencies below the Freq setting will be affected (Figure 11.3).

Figure 11.3. The Lo Shelf band affects everything below the Freq setting.

In the Hi Shelf band, all frequencies above the Freq setting will be affected (Figure 11.4).

Figure 11.4. The Hi Shelf band affects everything above the Freq setting.

Turn the Gain knob right to boost a frequency and left to cut.

Turn the Q knob right to sharpen the curve and left to make it more gradual.

As the Q value increases, a slight dip at the cutoff frequency occurs for positive gain, and a slight boost occurs for negative gain (Figure 11.5). This helps accentuate a boost or cut, allowing you to sharpen slight EQ adjustments to make them more audible.

Figure 11.5. The Q value creates an opposite dip when set high.
