Stereo Parametric EQ Use the Stereo Parametric EQ to emphasize or deemphasize certain frequenciesin your stereo audio tracks. For example, you can add or subtract brightness toyour audio, or alter the bass. You can control two frequency points with this effect, using either or both of them as a high pass, low pass, or boost/cut effect. High pass filters reduce frequencies below their frequency points; in other words, they 'pass' higher frequencies on without reducing them. In a similar way, low pass filters reduce frequencies above their frequency points, by 'passing' lower frequencies on without reducing them. Gain 1 Controls the amount of increase or decrease applied to the frequency set withthe Freq 1 control. Gain 2 Controls the amount of increase or decrease applied to the frequency set with Freq 2. Freq 1 Controls the center frequency for the amount of boosting or cutting set with Gain 1. Freq 2 Controls the center frequency for the amount of boosting or cutting set with Gain 2. Q1 Controls the 'sharpness' of the frequency curve. A low Q setting causes the boost or cut set with Gain 1 to be a wide, bell-shaped curve, affecting a wide range of frequencies. Ahigh Q setting causes the boost or cut to be a very steep point, affecting a smallrange of frequencies. Q values range from 1 to 30. (In more technical terms,the Q value is a proportion of the frequency you specify in Freq 1; for example, a setting of 30 means that you will affect a range offrequencies equal to 1/30th of the frequency you pick.) Q2 This control works identically to the Q1 control, except that it effects thefrequency and gain set with Freq 1 and Gain 2 . Type 1 Determines whether the boost or cut applied to Freq 1 acts as a normal boostcut, or whether it behaves as a high or low pass filter instead. To create ahigh pass filter, set this control to H, pick the frequency above which Metroshould pass the signal unchanged, then choose the amount of gain reduction appliedto the lower frequencies (you should use a value lower than 0). Type 2 This control works identically to the Type 1 control, except that it affectsthe frequency and gain set with Freq 2 and Gain 2 .
