Selecting the top soft key allows the user to adjust the overall delay of all four
outputs. Alongside the Main Delay value are the units used to display both the
Main and Band Delay values. The units can be changed in the Delay Utility
screen.
Refer to Section 8.0, Delay Utility Screen - Delay Units.
Delay Screen
Selecting the middle soft key allows the user to adjust a single band delay. Use
the parameter wheel push to step between the band delays, then turn the
parameter wheel to adjust the band delay.
Delays can be grouped together using the Delay Link utility in the Delay Utility
screen. Refer to Section 8.0 Delay Utility Screen - Delay Link. This allows the
user to link band delays that are used in a single cabinet. For example, if the
Delay Link is set up as ABC then the lower three delays will change together,
preserving any offsets previously set between the three delay values.If any
member of the link is selected then the speaker icons for ALL the members of
the group will be shown highlighted. If any of the delays reaches zero or the
maximum delay allowable (approximately 635milliseconds at 20
°
C, 68F) then
the three delay values will not adjust any further in that direction.
Selecting the bottom soft key allows the user to adjust the Polarity for each
band and the Phase adjustment at each crossover point if a filter has been
assigned to Phase for that band.
Polarity is selectable as either non-inverting ‘+’ or inverting ‘–’ and can be
applied individually to each band.
Phase, if selected, is adjustable from zero to 180
°
. The phase angle selected is
applied to the lower band of each crossover pair and is the phase adjustment
applied to the lower band output at the crossover frequency. Phase is turned
on and off in the EQ Utils screen and uses one of the two filters available for
each band. Refer to section 10.0 EQ Utility Screen, Filter Mode.
For a complete description of Temperature and Humidity correction Refer to
