Predelay

You will notice that there are two predelay parameters:

Early Predelay

Is an overall predelay that delays all of the signal. As with a more typical

reverb, it's often used to create some separation between the wet and dry

portions of the signal.

Reverb Predelay

Is an additional delay that comes between the room impulse and the

reverberation section. It can have a large effect on the perception of size

and/or liveness. A small value means that reverb will begin while the room

impulse is still being output. A larger value will delay the reverb until nearer

the end of the room impulse. An even larger value will create actual separa-

tion and may be perceived as a slapback.

Is used to change the size of a room impulse.

Controls the frequency of a filter that is applied to the room impulse. It works in

conjunction with Bass Boost.

Can boost or cut the signal below the Bass Xover value.

On the right side of the fader field, you will see a pair of drop-down menus and a but-

ton. The upper menu allows you to select a category of room impulses. The lower

menu allows you to select an impulse from the active category. The bottom button is

used to switch the impulse from Normal to Reversed, a rather significant effect.
