Delay Screen
7.0 Delay Screen
The delay screen gives the user access to the various parameters used for time
and phase adjusting the four output bands. The delays of the four bands can be
adjusted in one of three ways.
1 Individually - as would be used for time adjusting single speakers within a
cabinet.
2 In groups - for example, three output bands used to drive three speakers
within a single cabinet.
3 All four bands delayed together - as for a delay tower.
The ear to the left of the screen represents the listener, the line a little to the
right of the ear represents the overall delay of the unit. This line does not,
however, move as the overall delay changes, it is there purely to show the
individual band delays more clearly. If an individual band delay is set to zero
that band’s speaker icon will be positioned on the reference line. As the band’s
delay is increased, the icon will move away from the reference line and shift
toward the right - representing an increased ‘distance’ from the listener’s ear.
No scaling is intended between the pixels on the screen and the delays
represented; the speaker icons will automatically scale their positions to show
the relative delays between bands as clearly as possible.
The band names to the right of the band delay values are for reference only.
The names can be changed by the user in the ‘More Crossover’ screen. Refer
to Section 13.0 XOver More Screen.
