DX810 – 26
With the first band active (red active button lit),
click the
On
button to turn the crossover on and off.
When the crossover is turned off, all the outputs
assigned to the crossover pass a full-range signal.
Click the
Reset
button to return all the knobs for the
currently active band to their default settings.
Output:
Select the first output for the crossover
(
A-J
). Click the arrow next to the box to select an
output in the pull-down list. It appears in the first
Output
box. Repeat for up to five bands in a single
crossover system.
To deselect an output once you've selected one,
click the arrow next to the box and select the
"blank" line under the
J
output. This removes the
output selection from the crossover.
Polarity:
The
Polarity
button reverses the
polarity of the output by 180
°
.
Edit:
Click the
Active
button under
Edit
to adjust
the settings for the selected output. Then use the
Filter Type, Filter Slope, Alignment, Frequency
,
and
Delay Time
controls.
Filter Type:
Use this control to select high-pass
(
HP
), low-pass (
LP
), or band-pass (
BP
) filters for the
selected output. Notice that the
Frequency
control
selection changes to
High Freq
and
Low Freq
when
BP
is selected.
Filter Slope:
Use this control to choose the roll-
off curve for the frequencies above or below the
cutoff frequency. When
Butterworth
or
Bessel
alignment is selected, 12, 18, and 24 dB/octave
slopes are available. When
Linkwitz-Riley
is
selected, 12 and 24 dB/octave are available (18 dB
can’t be selected).
Alignment:
This switch selects either Linkwitz-
Riley, Butterworth, or Bessel characteristics for the
selected Filter Type.
Frequency:
This selects the cutoff frequency for
the selected filter, with a range from 20 Hz to 20
kHz. When a bandpass filter is selected,
High Freq
and
Low Freq
controls are available.
Delay Time:
This control adjusts the delay for
the selected output in small increments (22.7
µ
s),
with a range from 0
µ
s to 997
µ
s. The equivalent
distance the sound travels in the selected amount
of time is displayed.
Note:
This control is provided in the Crossover
window because the Delay Line DSP (the Delay
button) is situated prior to the crossover in the
signal chain. When the crossover is active, use this
delay control to adjust for offsets between drivers
in a stack. For example, use this control to time-
align a horn’s compression driver and a woofer’s
voice coil.
Option
This button is reserved for future upgrades.
Crosspoint Matrix Section
This section provides a view of all the input-to-
output crosspoints in the mixing matrix. It has a
numerical and graphical indication of the gain
setting for each crosspoint.
Click the associated letter button (
A-J
) in the
Output Section to select an output and the
horizontal row of input crosspoints is highlighted.
The input faders in the Input Section now control
the gain settings and mix for the selected output.
Either click on the fader or click on the horizontal
mini-fader indicator bar in the crosspoint to adjust
the gain for the input.
Click the select (
S
) button to select the
crosspoint for copying or pasting the level.
Otherwise, when a group is selected, use it to
assign the crosspoint to the selected group.
Input Section
This section includes the eight input faders along
with their associated bargraph input level meters,
Select and Mute buttons, and name box.
The fader adjusts the mix level from the input to
the output selected in the Crosspoint Matrix Section
(indicated by the highlighted row). The numerical
display for the level is shown at the crosspoint in
the Crosspoint Matrix section. Use the arrow keys
on the keyboard to make fine adjustments to the
level. Use the Page Up/Down keys to make course
adjustments.
