Time constants page

This page allows the attack and release time constants to be set - in other words how
quickly the unit will respond to a sudden increase in level (attack) or a sudden decrease
in level (release).

EQ settings page

EQ type - this allows control over the characteristics of the equaliser.

Proportional, Constant, and Symmetrical curves are available.

Graph display - two modes are available, to ensure that clear information is

available for any application. “Both” mode shows the overall response of the
whole dynamic equaliser. “Active” mode shows just the response of the single
section currently being selected for adjustment

pressing this allows an individual section to be switched in and out of

circuit.

On the Dynamic EQ page, the touchstrip can be used to select the currently-active section of
EQ. This is achieved by pressing either the upper or lower part of the strip below the centre
frequency of the chosen section. The centre frequency will highlight to indicate the selection.
Once selected, the frequency of the EQ section can be “dragged” up and down the display by
pressing the strip and sliding the point of contact to left and right. There is no difference
between the upper and lower strips when in Dynamic mode.
