Compress
Click this button to view the Compressor for a
selected input or output. Click an input SELECT
button to select an input. Then click the output
letter buttons (A-J) to select an output.
Click the On button to activate the Compressor
for the selected input or output. The Reset button
returns all the controls to their default positions.
The Compressor has five knobs: Attack, Release,
Output, Threshold, and Ratio. Click and drag on the
individual knobs to adjust each parameter. An
analog-style meter indicates the amount of
compression applied in decibels.
Click the right mouse button over the processor
display. This brings up a menu allowing you to cut,
copy, or paste the processor settings to
another channel.
About Compression:
A compressor is used to reduce or limit transient
peaks in a signal. As the input level to the
compressor increases, the output level increases
linearly until the threshold point is reached. After
that point, the output level no longer increases
linearly. Instead, it increases at a reduced rate
determined by the ratio setting.
This compressor features ‘soft-knee’
compression. The input signal level approaches and
crosses the threshold. Simultaneously, the
compressor gradually starts compressing. This
increases the ratio to the required setting smoothly.
• Threshold: This control determines the level around
which the compressor begins to act on the incoming signal. It is calibrated in decibels, with a range
from –60.0 dBFS to –1.0 dBFS.
• Attack: This determines how fast the compressor
reacts once the threshold has been exceeded. It is
calibrated in milliseconds, with a range from
0.1 ms to 2500 ms (2.5 seconds) per 20 dB of gain
change.
• Release: This determines how fast the compressor
turns off once the signal falls below the threshold.
It is calibrated in milliseconds, with a range from 10
ms to 2500 ms (2.5 seconds) per 20 dB of gain
change.
• Ratio: This determines the change in output level. It
is a function of the change in input level (at full
compression), once the threshold has been fully
exceeded. It is calibrated in decibels, with a range
DX810 – 25
from 1.0:1 (off) to 20:1. Thus, if it is set to 10:1, an
increase in input level of 10 dB results in a 1 dB
increase in output level. This assumes the input is
above the threshold level.
Generally, use ratio settings from 1.5:1 to 5.0:1 for compressor
use. Settings from 10:1 to 20:1 are more useful for limiting
purposes. This is because in that range the output level changes
very little as the input increases.
•
Output: This determines the overall gain of the compressor from
input to output (as measured with the signal below the threshold
level). You can use this control to compensate for the loss of gain
caused by the action of the compressor. It is calibrated in
decibels, with a range from 0 dB (unity) to +20.0 dB.
Gate
Click this button to view the Gate for a selected
input. Click an input SELECT button to select
an input.
Click the On button to activate the Gate for the
selected input. The Reset button returns all the
knobs to their default settings.
The Gate has four knobs: Hold, Release,
Threshold, and Range. Click and drag on the
individual knobs to adjust each parameter. An
analog-style meter indicates the input signal level
for the selected channel.
Click the right mouse button over the processor
DX810 – 26
display to bring up a menu that allows you to cut,
copy, or paste the processor settings to
another channel.
About Gating:
A gate is used to duck or mute a channel when the
signal level drops below a certain point. This can
reduce the overall noise level in your mix by muting
unused or noisy channels.
Note: When we say the gate opens, it means the
gate is not acting on the signal and the signal is
allowed to pass. When the gate closes, the gate
acts on the signal by attenuating it.
• Threshold: This determines the level below which the gate
closes (and above which it opens). It is calibrated in decibels,
ranging from –60 dBFS to –1 dBFS.
•
Hold: This determines how long the gate remains open after the
input signal has fallen below, and remains below, the threshold
before closing. It is calibrated in milliseconds, ranging from 0 ms
to 2550 ms (2.55 sec).
•
Release: This determines how fast the gate closes after the hold
time has expired. It is calibrated in milliseconds, ranging from 10 ms
to 2500 ms (2.5 sec) per 20 dB of gain change.
•
Range: This determines the amount of attenuation of the input
signal when the gate is closed. It is calibrated in decibels, ranging
from –100 dB to –1 dB.
Delay
Click this button to view the Delay settings for a
selected output. Click the output letter buttons (A-J)
to select an output.
Click the On button to activate the Delay Line.
Click the Metric button to change the settings from
inches/feet/Fahrenheit to mm/meters/Celsius. Click
the Reset button to return all the knobs to their
default settings.
The Delay Line has three knobs: Temp, Coarse,
and Fine. Click and drag on the individual knobs to
adjust each parameter.
Temp: The speed of sound varies with air
temperature. Therefore it is necessary to enter the
ambient air temperature. This is in order to
accurately calculate the time delay required as a
function of distance traveled. This control is
calibrated in degrees, ranging from –40°F to 122°F
(–40°C to 50°C).
Coarse: This control adjusts the delay in 1
millisecond increments, with a range from 0 ms to
200 ms. The equivalent distance the sound travels
in the selected amount of time is displayed. Use
this control when setting up a delay between two
speakers, as in a delay tower.
Fine: This control adjusts the delay in small
increments (22.7 µs), with a range from 0 µs to 997
µs. The equivalent distance the sound travels in the
selected amount of time is displayed. Use this
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.
Click the right mouse button over the processor
display. This brings up a menu allowing you to cut,
copy, or paste the processor settings to
another channel.
X-Over
Click this button to view the 1 to 5-Band
Crossover. The crossover window has a graphic
display to indicate the number of bands and
crossover points selected. Up to five outputs can be
selected, which become linked to a single row of
inputs. In other words, each of the eight inputs has
just one mix level to the combined outputs in the
crossover. This is reflected in the Crosspoint Matrix
Section by “blanking out” all but the top row of
crosspoints for the linked crossover outputs. Note
that only contiguous outputs may be linked to
create a crossover.
Linking outputs together for the crossover
automatically links those outputs in the Parametric
EQ and the Graphic EQ processors.
The equalizers are located prior to the crossover
in the signal chain, so all the outputs assigned to
the crossover are affected by the EQ settings.
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). It appears in the first Output box. Click the
arrow next to the box to select an output in the
pull-down list.
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
Frequency, Filter Slope, Alignment, and Filter
Type 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.
Alignment: This switch selects either LinkwitzRiley (L) or Butterworth (B) characteristics for the
selected Filter Type.
Filter Slope: Use this control to choose the rolloff curve for the frequencies above or below the
cutoff frequency. When Butterworth alignment is
selected, 12, 18, and 24 dB/octave slopes are
available. When Linkwitz-Riley is selected, 12 and
24 dB/octave are available.
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.
Option
This button is reserved for future upgrades.
DX810 – 27
Crosspoint Matrix Section
This section provides a view of all the input-tooutput 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.
DX810 – 28
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.
The input level meter indicates the level of the
input signal as it comes out of the analog to digital
converters and shows the level in dBFS. If the red
0 dB portion is lit, then the signal level is above –
2 dBFS and may be clipped. Note that the meter
indicates the signal level before any processing or
digital gain stages. If the signal is clipping, or is too
low, adjust the signal level at the source, or use the
trim pots on the rear panel of the DX810.
Click the SELECT button when a group is
selected to assign the input to the selected group.
The assigned group fader then affects the signal
level for that input to all ten outputs. Click the
SELECT button when the gate or compressor
windows are showing to adjust the processing
options for that input.
Click the MUTE button to mute the input signal to
all ten outputs.
Use the name box at the bottom of the Input
Section to enter a name for the input (e.g., CD Left,
CD Right, Vocal, Guitar, etc.), up to 32 characters.
Output Section
The Output Section includes the ten output
faders along with their associated bargraph output
level meters. This section also includes numerical
gain display, mute and solo buttons, and name box.
Use the output faders to adjust the final output
level of the signal. Adjust the output faders so that
the associated output meter indicates around the
–10 and –7 dB positions when a normal signal is
going to that output. This provides the best signalto-noise ratio for the output stage. It’s okay for the
–4 and –2 LEDs to blink occasionally on musical
peaks. However, avoid allowing the red 0 dB
indicator to light, which indicates that the signal is
within 2 dB of clipping.
Note that the meter indicates the signal level
after the output signal processing (i.e., Graphic EQ,
Parametric EQ, Compressor, Crossover). If
adjustments are made to the output processors, the
output fader may need to be readjusted. This is to
compensate for an increase or decrease in gain
through the processors.
Click the (M) button to mute the output signal.
Click the (S) button to solo the output. This
mutes all the outputs except the soloed output.
This is useful for troubleshooting and listening to
each output individually.
Click the letter button (A-J) when a group is
selected to assign the output to the selected group.
Click the letter button when a processing window is
showing (except Gate and Input EQ) to adjust the
processing options for that output.
Use the box to the right of the Output Section to
enter a name for the output (e.g. Main Left, Control
R), using up to 32 characters.
Group Section
This section includes the 32 control groups.
Eight groups are displayed at one time. However,
the horizontal fader at the bottom allows you to
scroll through all the control groups.
To assign or unassign a crosspoint or output to
a group:
1. Click the select (S) button for the desired group. If any
crosspoints or outputs are assigned to the selected group, their
select buttons light.
2. Click the select (S) button for the crosspoints you want to assign
to the selected group. The group fader affects the mix level for
each crosspoint to a single output.
3. Click the SELECT button in the Input Section to assign the input
fader to the selected group. The group fader affects the mix level
for each input to all the outputs.
4. Click the associated letter button (A-J) in the Output Section to
assign an output to the selected group. The group fader affects a
single output level.
5. Click the Groups button in the Top Section to view and verify
group assignments.
Group assignments are saved in each preset.
This allows different combinations of crosspoints,
inputs, and outputs to be assigned to the same
group number in separate presets. This is useful for
room combining applications.
Click the (M) button to mute the group. This
mutes all crosspoint, inputs, and outputs assigned
to the group. Click the Mute Ind button to view the
Active Mute Groups indicator.
The group fader controls the relative level for all
the crosspoints, inputs, and outputs assigned to it.
At the unity gain position (U), all the levels are at
their assigned values and the group fader has no
effect. Reduce the group fader 10 dB, and all the
levels assigned to that group are reduced 10 dB,
relative to their assigned value. Note that the group
fader can increase the level 10 dB. However, if an
assigned level is already at +10 dB, it will not
change. The maximum overall gain available for any
crosspoint, input, or output is +10 dB.
Use the box at the bottom of the Group Section
to enter a name for the group (e.g., Voc, Drum),
using up to 32 characters.
There is a mute and select button associated
with each Control Group.

differ in some respect from its published
description, but will always equal or exceed the
original design specifications unless otherwise
stated.
