DMP1616 / DMP1616D
Below you will find the onboard signal processors of the
DMP1616 and information on their use and respective
parameter. These can be applied to any of the 8 input or
8 output channels of the DMP1616.
Compressor-Limiter
Compressor Threshold: Use this control to set the
threshold of the compressor function. Any signals that
surpass the selected threshold will be compressed at the
selected ratio.
Compressor Attack: This control adjusts the attack
time of the compressor, essentially determining the time
taken for the compressor to kick in after it passes the
selected threshold.
Ratio: This control can be used to set the ratio for the
compressor. The ratio is expressed as <input>:<output>.
Compressor Release: The release control determines
the time the DMP1616 will wait before disengaging the
compressor when the signal bypasses the selected
threshold.
Limiter Threshold: This control determines the threshold
for the limiter function. This means that no signal will
surpass the selected threshold, being ‘compressed’ at a
ratio of infinity:1.
Output Gain: This control determines the amount of
gain applied to the signal after already passing through
the compressor-limiter.
On & Reset Buttons:
The on button is, of course, used
to turn the Compressor-Limiter on and off, while the reset
button will reset all values to default.
Gate
On: This button turns the gate on and off.
Reset:
Push the reset button to restore all parameters
back to default.
Dynamic Graph:
This graph shows the currently set
gate properties and how it will affect your audio.
Level Meters:
These meters give the input and output
level of the gate for the current channel.
Gain Reduction:
The gain reduction meter will provide
a real-time indication of any reduction in signal caused
by the gate.
Threshold: This control will set the threshold of the gate
function. Any signals that fall below the set threshold will
activate the gate function.
Range:
This control sets the amount of attenuation when
the gate is closed.
Attack:
This control adjusts the attack time of the gate.
This is the time the DMP1616 will wait after the signal
drops below the threshold before engaging the gate.
Hold: The hold will allow you to select the length of time
the gate will remain open after the signal drops below the
set threshold.
Release:
The release control determines how long the
gate will wait before disengaging when the signal rises
back above the selected threshold.
SIGNAL PROCESSORS
Expander
On:
This button turns the expander on and off.
Reset: Push the reset button to restore all parameters
back to default.
Dynamic Graph: This graph shows the currently set
expander properties and how it will affect your audio.
Level Meters: These meters give the input and output
level of the expander for the current channel.
Gain Reduction: The gain reduction meter will provide
a real-time indication of any reduction in signal caused
by the expander.
Threshold:
This control will set the threshold of the
expander function. Any signals that fall below the set
threshold will activate the expander at the user-set ratio.
Ratio: This signal sets the ratio of the expander function.
When a signal drops below the threshold, the signal will
be decreased by the selected ratio.
Attack:
This control adjusts the attack time of the gate.
This is the time the DMP1616 will wait after the signal
drops below the threshold before engaging the gate.
Release: The release control determines how long the
gate will wait before disengaging when the signal rises
back above the selected threshold.
Delay
Adding a delay on output can be particularly helpful to
help time align drivers within a single cabinet or help avoid
delay in larger multi speaker setups. For example, when
there are a number of drivers in a single cabinet, typically
they’re different distances from the front of the cabinet.
The tweeter, typically longer than the woofer, could have
its driver 8 inches deeper than the woofer. The problem
this creates is the sound from the woofer will be pushed
out a fraction of a second before the tweeter, arriving at
the wavefront at different times. Adding a 0.6 millisecond
delay to the woofer can combat this, essentially making
the signal wait for the tweeter to catch up.
Delay:
Use this control to adjust the delay time. To the
right of the control, the selected delay will be indicated in
milliseconds, meters and feet.
Temperature Control: This allows you to set the
current temperature for the delay circuit. This allows the
DMP1616 to better refine the delay’s ‘meter’ and ‘feet’
results. The temperature is indicated in both degrees
Celsius and degrees Fahrenheit.
On & Reset Buttons:
The on button is used to turn the
delay circuit on and off. The reset button resets all values
to default.
Signal Generator
Type: Select from Pink Noise, White Noise, Sine or
sweep waves.
Frequency: Adjust the frequency of the sine wave
between 20Hz and 20KHz, as required.
