6. PARAMETER MENUS DESCRIPTION
- HUM CANCEL: allows the modification of the dynamic NOTCH filter parameters. The graph included shows the
filter response curve.
- NOISE GATE: allows the modification of the noise gate parameters. The graph included shows the filter curve.
- MULTICOMP: allows the modification of the multiband compressor parameters. The graphs below show the response
curves of the two compressors.
- DELAY: allows to apply a delay to each amplifier's channel, with the possibility to set it in metric units (millimeters
and meters) and time unit (microseconds and milliseconds). It's also possible to set the ambient temperature for the
correct conversion of the distances in delay time.
- CROSSOVER: allows the modification of the HPF and LPF CROSSOVER filters, including FREQUENCY, TYPE
(Linkwitz/Riley, Bessel and Butterworth), SLOPE (6, 12, 18, 24 or 48 db/oct.) and PHASE (related to the LPF fre-
quency). The graph below shows the response curves of the selected channel.
- EQ: allows the modification of the EQ filters parameters. The graph below shows the response curves of the input.
The 10 EQ filters can be edited not only typing the values in the parameter fields, but also in a graphic way. Each
filter is identified by a different color: dragging the red box on the response curve, frequency and gain of the corres-
ponding filter will be modified at the same time.
- GAIN / COMP: allows the OUTPUT LEVEL, the MUTE, the PHASE and the COMPRESSOR/LIMITER parameters
to be set. In addition, in this page the output levels and the LIMITER action are displayed.
- GLOBAL: this windows shows the response curves of the system's outputs.
7. WORKING WITH PRESETS
At the lower edge of the PC Editor window is a series of commands for recalling and storing PRESETS.
To load a PRESET:
Click on and then on one of the numbered red (FACTORY) or green (USER) PRESET buttons. The selected
RECALL
PRESET will be loaded and its name displayed in the text box.
To save a PRESET:
Click on and then on one of the grey or green buttons (USER PRESETS). The grey color means it is an empty
STORE
PRESET. The green color means there is already a set-up stored at that position (which will be overwritten if you pro-
ceed). In the window that appears, type a new PRESET NAME, then press
. The new setup is now saved as a
OK
PRESET, with its name displayed in the text box. But you still need to save to a file, as follows:
Save All Settings:
Remember that every time you download from your PC to the DPA unit, the USER PRESETS in the internal memory
are replaced.
You must now save your settings (which may include several different PRESET set-ups) as a Maxi Editor File
(*.mxe) on your computer. Go To
, and then . A window will open for you to select a destination folder
FILE SAVE AS
for the file. You can keep the default filename or type one of your own.
When you have done this, take the offline (click on the icon) and then online again. This will force the PC Editor to do
a network scan. Press
and the full system settings, including your latest PRESET, will now be downloaded and
OK
stored in the unit's internal memory.
