When the EQ is switched to ‘E’ operation, the bandwidth of the HMF and LMF sections remains constant at all gains, so at lower gains the EQ curves are comparatively narrower for a given Q setting. This is particularly useful for drums, since relatively high Q is available at low gain settings. However, it is not so suitable for overall EQ or subtle corrections, as you need to adjust the Q to maintain the same effect when the gain is changed.
∙Normal (G type) curves with the ‘E’ switch OUT, have a modified slope with a degree of overshoot/undershoot for increased selectivity
∙‘E type’ curves with the ‘E’ switch IN follow conventional cut or boost characteristics
The two parametric bands have selectable characteristics which affect the relationship between frequency bandwidth and gain:
With the ‘E’ switch OUT, the frequency bandwidth reduces with increased gain, thereby increasing the selectivity of the EQ as the gain is increased.
With the ‘E’ switch IN, the frequency bandwidth is constant at all gains. At full boost or cut both are identical.
There are three buttons associated with this section of the
EQ IN : Switches the EQ section into circuit.
E: Switches the EQ from ‘G’ operation to ‘E’ operation - see below.
DYN SC : Switches the EQ section into the sidechain of the Dynamics section. The Filter Section can be switched independently of the EQ section. If both Filter and EQ sections are assigned to the dynamic sidechain the EQ section precedes the Filter.
