Chapter 29 Ultrabeat 577
Two Band EQ
Both equalizer bands have almost identical features. Their parameters are explained
jointly, but you can, of course, adjust band 1 (the upper EQ in the Output section) and
band 2 separately.
Clicking on the Band 1 and Band 2 labels turns the individual band on or off. When
active, the field is red. If neither EQ is activated, the signal passes through unaffected.
The EQ type buttons switch between two different types of EQs: shelving and peak.
In shelving mode, all frequencies above or below the set frequency are either increased
or reduced. In peak mode, only frequencies located near the set frequency are affected.
The shelving EQ is activated by clicking the upper of the two EQ type buttons. The
peak EQ is activated by clicking the lower of the two EQ type buttons.
Band 1 offers a low shelving EQ while band 2 features a high shelving EQ. Low shelving
means that the frequencies below the set frequency are affected. High shelving affects
frequencies above the set frequency.
Note: Shelving EQs function similarly to synthesizer lowpass and highpass filters. The
fundamental difference: while lowpass and highpass filters merely dampen certain
frequencies (filter them out), shelving EQs also allow these frequencies to be boosted.
The EQ Gain knob is bipolar. Positive values boost a certain frequency range as
determined by the EQ type and Hz settings. Negative gain values lower the gain of the
frequency range. If the Gain knob set to the mean value of 0, the EQ has no effect.
Note: You can also return this knob to its neutral position by Option-clicking on it.
Alternately, you can click on the tiny 0 above the EQ Gain knob.
The frequency is set by click-dragging vertically on the Hz parameter field. This
determines the frequency range to be boosted or reduced.
